Raw Blame History

Major changes from 1.0 to 1.1
+ Everywhere: Can compile two versions of the code, under gcc or bcc
(Bruce Evan's cc), so that 16-bit boot PROMs can be made. See
netboot-16/README.16 for more details.
+ Everywhere: Removed duplicate defines, e.g. everybody defined their
own ID for ethernet address size (6). Put IDs for magic numbers in
various places. Still some inconsistency, ETH_ and ETHER_ are used.
+ Everywhere: Added prototypes of functions to netboot.h. Removed
unused variables.
+ Makefiles: Rewritten.
+ netboot.h: Added define for TFTP_MAX_PACKET = 512. Increased TIMEOUT
for tftp packets to 180 (about 10 seconds) so that tftp servers would
be able to retransmit blocks.
+ main.c: Rewrote tftp(). Original was intended to get only one block
and the strain on the structure due to modifications was showing.
Increased config_buffer size to TFTP_MAX_PACKET+1 to avoid special
casing data length=512.
+ linuxloader.c: Cleaned up the code in some places, especially
linux_tftp. Moved the bootp reply block into bss space instead of a
fixed location such as 0x90000.
+ ns8390.c: Removed one bug regarding packet length. packetlen was
wrongly shortened when packets wraparound the ring buffer.
+ 3c509.c: Changed some of the gotos to returns. Removed ARP code since
that's already done elsewhere. Removed interrupt enable and Rx early
notification (we can't do anything with the packet until it's complete
anyway).
Major changes from 1.1 to 1.2
+ Small bug in makerom.c. Extra semicolon shortened for loop and made
double checking code invalid.
+ Added version identification to startup string.
+ Gathered external declarations into netboot.h.
+ New compile time option for netboot-32. If INT19H is not defined,
then boot ROM takes control as soon as BIOS scans it. This may solve
the problem of some BIOSes not calling the boot ROM at INT19H. This
may be when disks are detected by the BIOS, i.e. the machine is not
truly diskless.
+ Added a new program, test.c, for making test ROMs to verify that
the BIOS recognises the ROM.
+ New directory contrib contains contributed code. Currently contains
masq by Gerd Knorr: make a boot floppy without DOS
comboot-1.0 by Adam J. Richter: also make a boot floppy without DOS.
+ New mknbi-1.4 from Gero Kuhlmann and Markus Gutschke. This one handles
the new bzImage format.
Bumped up version to 2.0 because we are so listed in the Linux 2.0
distribution and this would avoid confusion.
Major changes from 2.0 to 2.1
+ Added LSM for transname-patch to contrib.
+ Added patch for serial console from Claus Heine
<claus AT momo PERIOD math PERIOD rwth-aachen PERIOD de>.
+ Claus Heine contributed patches to the 2.0.21/22 kernel sources to
allow NFS swap.
+ Markus Gutschke provided fixes to start2.S so that main can return to
the ROM code if user doesn't want to ROM boot.
+ Added code to main.c to timeout on the prompt and assume Y or N
for the answer. Timeout and answer configurable.
+ Made NE1/2000 probe addresses configurable from Makefile. Fixed up
autoscan code.
+ Made NFS_BOOT a configurable option. By undefining it, only tagged
file load is supported but ROMs are under 8k.
+ ROMSIZE is not used by makerom now. -s flag controls size of ROM
at runtime. So don't need to recompile makerom if ROMSIZE changes.
+ Updated netboot-16 for the latest dev tools from the Linux-MT
project. Use the size.c from there.
+ Got rid of _main() in main.c, instead using #ifdef ELF in start2.S.
ELF is preferred now anyway.
+ Changed bcompare to standard bcmp and reversed sense of result.
Reason: to use standard library if available, e.g. Netboot-16.
+ Common Makefile for 32 bit and 16 versions, with differences in
Config files.
Major changes from 2.1 to 2.2
+ New device driver for the Crystal Semiconductor CS89x0 chipset family.
(because of legal problems, this code is currently in the "contrib"
directory.)
+ Added support for loading BOOTP extension files (c.f. RFC1533).
+ If we have to go thru a gateway, then use the one that has been used for
the BOOTP daemon. If the BOOTP daemon is directly accessible, then use
the first entry in the "gw" gateway list instead.
+ For all retries, back off according to RFC951 by randomizing the timeouts
and exponentially increasing them until an average of one minute is
reached.
+ Warn if code will not fit into chosen ROM size. Happens only if the
autosizing in the Makefile somehow fails.
+ Modified the code for enabling the A20 gate; this could increase
compatibility, but I still have to hear from users.
+ The copyright message will now reflect, which features have been
enabled at compile time.
+ Added support for selecting different boot images from a menu. As a side
effect, this can be used to upgrade the ROM without having to burn a new
image (c.f. README.VendorTags).
+ Display a "message of the day" that is provided by the BOOTP daemon.
+ The sanity check for detecting a Linux kernel was too strong to properly
recognize a 2.1.x kernel; this has been fixed.
+ Trys to negotiate for 1432 octect blocks, if the TFTP daemon knows
about RFC1783.
+ We can optionally boot from local disk, if the BOOTP server cannot
be contacted.
+ Restructured directories: got rid of netboot-freebsd to reduce confusion
with Gero Kuhlmann's netboot, moved documentation to doc and renamed
directories to be more in line with Unix conventions. Edited documentation.
+ Created a dispatch table for NIC routines so that we can include one
or more drivers in one binary. Renamed all entry points in the driver
sources. Created two new files, config.c, which holds the dispatch
table and can be conditionally compiled; and nic.c which contains the
extern variables referenced by the drivers.
+ Automatically decide what size ROM is needed by doing a size and then
choosing the correct startup object. Currently caters for 8k, 16k and
32k ROMs.
+ Optionally include a simple interpreter for ANSI escape sequences. This
allows for fancier boot menus.
+ Remove patches directory which is mostly relevant to 1.x kernels only.
Everybody should use 2.x kernels now. If for some reason you need those
patches, get an older release of etherboot.
+ Fix Makefile to work even if . not on PATH.
+ Sadly, 32 bit ROMs are now > 8kb. We will try to reduce the size by
conditionals in a later release. For now, use version 2.1 if your NIC
won't take > 8kb ROMs.
+ Release as 3.0b1 because of the large amount of changes.
+ Fixed a few problems with the code for ANSI escape sequences and
added optional support for displaying graphics.
+ Optional support for password protected boot images.
+ Optional support for booting from block devices (floppy, hd).
+ The bootp server can pass additional parameters to the loaded kernel
image (currently, this only applies to Linux) and the user can be
allowed to edit a commandline; the latter is optionally protected by
a password scheme.
+ Set the warm-boot flag when the main routine is entered.
+ Release as 3.0b2
+ Added code for updating the FlashCard EPROM over the network
(contrib/flashimg).
+ Added very simple code for turning a ROM image into a network loadable image.
This is useful for debugging, but some users without flash EPROMs might
appreciate the possibility to load a fully fledged image from a very basic
configuration.
+ Optional support for compressing the ROM images. Please read
doc/COPYING.compressor before using this feature.
+ Sync'd our source tree with Gero's netboot-0.5; this means that you now need
the as86 from the ELKs project in order to recompile all of the files. This
should not affect normal usage, though.
+ Added "mknbi-blkdev" for booting from local block devices.
+ Fixed some bugs in ppmtoansi.c and bootmenu.c
+ Renamed reference compressor implementation to compressor.exp otherwise
make tries to use it and it should not be turned on by default.
+ Zero'ing BSS in 16-bit version has to be done to _end, not to A0000
because it's executing in a segment, not in flat address space in 16
bit mode.
+ Ken Yap contributed a quick and dirty Perl script for people who use
netboot to test ELKS. So far I'm the only one I know of; maybe the
others are silent. :-(
+ Release as 3.0
Major changes from 3.0 to 3.1
+ 4 versions of etherboot can be built for a NIC: .com for testing and
.rom for burning into EPROM, and corresponding compressed versions:
.lzcom and .lzrom.
+ The loaders are now separate programs which are prepended to the
etherboot binary. This allows them (plain and uncompressing versions) to
be maintained separately and gives a bit more RAM to the etherboot code.
+ No need to define ROMSIZE in the build. makerom automatically discovers
the ROM size needed and fills in the size field in the ROM. This
simplifies the build procedure.
+ 16 bit versions use the same loaders as the 32 bit version. Also fixed
two bugs in the 16 bit versions: (1) a non-8086 instruction in zloader,
(2) setting warm-boot flag in main which zapped some code.
+ Fixed a documentation bug on the ANSI escape sequences.
+ Include netboot-0.5.3 distribution from Gero Kuhlmann.
+ Included some contributions from Dickon.Reed AT cl PERIOD cam PERIOD
ac PERIOD uk: Running display of Kbytes loaded, line of delimiters after
loading complete, a temporary hack to address timing problems with the
3C509, and some Makefile cleanup. The first two changes need to be
enabled in Config with defines.
+ mknbi-blkdev seems to have been left out by Gero Kuhlmann. Add to
contrib directory. You probably have to make a symlink to it from
the netboot-0.5.2 directory.
+ Release as 3.1
Major changes from 3.1 to 3.2
+ 16 bit version now can load to extended memory, if it exists. On
a 8086/8 this will silently fail.
+ Cleaned up interface between main body of code and NIC drivers. No
global variables referenced in NIC driver, everything is passed
through a structure. Only the probe function is visible outside,
pointers to the others are returned in the structure.
+ Implemented autoprobe for 3c503. Also simplifies code at same time.
+ Removed ARP response code in ns8390.c. Don't think we need to respond
to ARP requests because other machines will do gratuituous ARP when
boot code sends out bootp request. Are there cases where this is not
true? Gateways?
+ Added 1 second timeout to routine that clears the keyboard buffer
in case there is no keyboard.
+ Added a skeleton driver that can be used as a template for new NIC
drivers.
+ ./lzhuf in Makefile so that it will run even if . is not on path.
+ Fixed comboot to work on 286s also. Won't work yet on 8086/8.
+ Fixed mknbi-blkdev to configure properly under netboot-0.7.
+ Added David Munro's PCI code adapted from Linux. Currently has entries
for PCI NE2000 clones. Generalised it to probe other PCI cards later on.
+ Moved twiddle() outside NIC driver except where used to provide a delay.
+ Fixed bug in Makefile spotted by Ton Biegstraaten. Should prepend
ZLOADER to make all.lzcom, not LOADER.
+ Charlie Brady donated a NE2100 (LANCE) card, so Ken Yap wrote a driver
for it. Should work for other LANCE (7990, etc) based cards with some
modifications.
+ Markus Gutschke wrote rom-scan, and it is in contrib/.
+ Hack rom-scan.c so that a DOS version can be compiled.
+ Removed all.* targets from Makefile. The NIC specific loaders should be
used in preference as the all.* loaders can run out of memory.
+ Added a disable routine to dispatch table so that cards can be turned
off before the loaded code is executed.
+ Make INT19H the default.
+ Rogier Wolff persuaded AW computer systems to contribute the Intel
EtherExpressPro 100 driver. The binary to hex converter in contrib/
is also from Rogier Wolff. Part of the work is sponsored by BitWizard
NL (www.bitwizard.nl).
+ Distribute with a subset of netboot-0.7.2 that doesn't have the bootrom
portion.
+ Release as 3.2.
Major changes from 3.2 to 4.0
+ Merged in Vlad Lungu's patches for DHCP support, ifdef'ed by DHCP_SUPPORT.
+ XID matching fix also provided by Vlad Lungu.
+ Merged in William Arbaugh's patches to make eepro driver work properly.
+ Add to contrib/ better bin2intelhex from Jean Marc Lacroix.
+ Patches from Jim Hague (thanks!) for the following:
* Added PIO mode for 3c503 to ns8390.c. Changed the card detection to
detect shared memory or PIO and use the selected one, and removed
a jumper check that failed on the Bull (no jumpers).
* Added more #ifdefs to ns8390.c to include only code relevant to the
card being compiled, and removed unnecessary run-time card vendor
behaviour branches - it's all now #ifdefd.
* Added a -3 parameter to makerom to set the last two bytes to 0x80.
These are the values they have in the 3Com Etherboot image that was
in the Bull. (Also on the 3c503 card I have - Ken.) Also altered the
Makefile to add this parameter when building a 3c503 image.
* Modifies lzhuf.c, objdump86.c & size86.c to work on either-endian systems.
* Adds a -DT503_AUI config paramter to let you choose AUI or BNC on
3c503s. Previously it defaulted to AUI, and you had to change the
code to alter it.
* Changed the BCC include directory to /usr/bcc/include. If you use the
BCC include files they don't define u_char, u_short etc. I've added
these into linuxdef.h, ifdef'd on BCC.
* Adds a trivial Linux 3c503 driver patch to the contrib directory
to let it spot these 'ere Bull things.
+ Charlie Brady confirmed that the Lance driver works with PCI so there
is a new lancepci driver now.
+ Removed support for NFS_BOOT; only TFTP booting supported now.
+ Removed support for linear images; only tagged images supported now.
+ Removed PRIORIZEBOOTPKERNEL and BOOTPKERNELONLY. Bootp reply must
specify kernel name.
+ Bug fix for 16 bit version of 3c509 driver: sign bit propagation bug.
+ Revert to non-pausing versions of out[bw] and inb for NEx000 driver
because of reports of timimg problems on some cards.
+ New driver for NI6510. Just a simple tweak of the lance driver for
different ID bytes and different register offsets. According to the
NI6510 driver in Linux, the NI6510 Etherblaster is more like the NE2100
and would be detected by the NE2100 driver. So use that one instead.
+ New drivers for 3c507 and NI5210, both of which use the i82586 chip. It
works properly for both now. I needed to have enough receive buffers to
make sure i82586 never goes into an out of resources state. 3c507 driver
has one quirk, it only responds after second bootp request. I seem to
remember something about this problem of losing the first packet after
initialisation in early Linux discussions. I am also now convinced
that Intel designers have weird minds. BTW, NI5210 driver assumes 8k
RAM because if you put the ROM on the NIC you can only have 8k RAM. If
you are putting the ROM off-board and you want 16k, well, talk to me.
+ Call nic_disable routine just before jumping to loaded image. This
does nothing in most drivers, but may have side effects as the nic_reset
routine used to be called instead.
+ One of those "why I didn't think of it before" ideas: A modified version
of comboot, called floppyload, that is prepended to the .rom image rather
than the .com image and then both written raw to a floppy for testing the
bootrom. All we have to do is jump to an entry point in (z)loader that
skips the INT19H stuff. Relocation will happen automatically. Now the
.com images and comboot are superfluous, unless one is masochistic enough
to want to try to test under DOS.
Added .fd0 targets to Makefile. Saying make <card>.fd0 will make
floppyload.bin and <card>.rom, and cat both to /dev/fd0. Naturally the
drive must be writable and you must have a floppy in the drive.
+ New driver for Tiara (Fujitsu EtherStar). This was one of the easiest
drivers to write. But the chip apparently has some quirks; there is no
Linux driver for it in the standard distribution and the email address
of someone who wrote an alpha driver is invalid. Perhaps I'll bump into
an AT1700 (which has a similar chip) one day and be able to reuse a lot
of the code.
+ Updated contrib/mkelksnbi for ELKS 0.0.68.
+ Confirmed that the SMC8216 driver works. 8416 not tested, it's a PnP
card. Can anybody confirm this?
+ New contributed software: p910nd, a tiny printer daemon suitable for
diskless hosts.
+ Made ANSIESC work for Etherboot/16.
+ Fixed Makefile and Config.* so that it works with old binutils.
+ Included a subset of netboot-0.7.3.
+ Released as version 4.0.
Changes between 4.0 and 4.1
+ Patches by Andrew Coulthurst for eepro100b.
+ Patches by Doug Ambrisko for booting Windows95 after answering N to
the boot from network question. Added conditional code to cope with
broken DHCP server and TAG 128.
+ Put version and driver identifier at end of ROM image if it fits,
to help identify ROMs in future.
+ Capture ROM segment address and length to help choose between multiple
NICs later.
+ Don't clear all of memory because it will destroy return address
on stack.
+ Changes to comboot-1.2 (although obsolete) to run on 8088s.
+ New version 0.2 of p910nd, a non-spooling printer daemon.
+ Patches by Alex Harin to prepended loaders and makerom to generate PnP
ready ROMs. Modified makerom to automatically detect PnP and PCI headers
and do the right thing. Added option to change the vendor and device IDs.
+ Augmented documentation for 2.1 and above kernels. Kernel now wants to
mount /tftpboot/<hostname in bootptab> rather than /tftpboot/<ip address>
as the root FS.
+ Changed all the outb* and outw calls in drivers (except eepro) to be
OUTB* and OUTW, then defined macros to translate to out[bp]* for both
Etherboot/32 and Etherboot/16, instead of pasting macros from Linux
include files because apparently they've changed in 2.1. At the same
time reversed the arguments in start16.S for outb and outw to match the
Linux convention. Unfortunately the out[bw] usage came that way from
FreeBSD. Someday I'll reverse the arguments in the C files properly.
For any new driver writers, you should use the Linux order now.
+ New contributed utility, disnbi for decoding and extracting network
boot images.
+ Martin Atkins contributed mntnbi for mounting DOS NBIs.
+ Peter Dobcsanyi contributed vendor and device IDs for the Netvin
NE2000/PCI clone.
+ adam AT mudlist PERIOD eorbit PERIOD net contributed RARP code as
alternative to BOOTP/DHCP. Activated by RARP_NOT_BOOTP define.
+ Added link to Claus-Justus Heine's NFS swap Web page and updated the
contrib directory.
+ Disabled max packet length check in ns8390.c. Caused spurious Bogus
packet messages in some cases and doesn't seem that useful a sanity
check anyway.
+ Daniel Engstrom contributed a SMC9000 driver.
+ Didier Poirot contributed an Etherpower II (EPIC 100) driver.
+ Added bug fix by Attila Bog<6F>r for bootmenu.c and patch to main.c to
remove looping menus on failure. Also code for ARP replies and TFTP
block retransmit (#ifdefed because controversial).
+ Code cleanup of tftp and tftpd also by Attila Bog<6F>r.
+ Nathan R. Neulinger fixed a bug with block being declared short instead
of u_short in tftpd.c, which limited transfers to 32k blocks. Fixed
problem with field tu_block being declared as signed short in many
platforms by including fixed version of tftp.h. Fixed tftp also for
good measure.
+ New mini-HOWTO on a "ssh terminal".
+ Andreas Mack pointed out that eepro100 doesn't compile on 2.1 and
2.2 kernels. Removed unnecessary include of bios32.h and reliance on
definition of virt_to_bus in kernel headers in eepro100.c, epic100.c
and lance.c.
+ David Sharp contributed a Tulip driver written for FreeBSD netboot.
Ken Yap ported to Etherboot. Not tested yet because no hardware.
+ Replaced references to arptable[ARP_CLIENT].node to nic->node_addr in
eepro100.c and epic100.c as they should be.
+ Greg Beeley of LightSys Technology Services contributed a 3c905b
driver. Be sure to read the release notes in 3c905b.txt.
+ G<>nter Knauf suggested making the prompt strings more generic and to
put a newline after the answer. Beware, N now means Network boot and
not No to network boot.
+ Alex Nemirovsky contributed some patches for BIOSes that use an extended
space at the top of 640k. Also some code for BIOSes that don't implement
BIOS32 correctly or at all.
+ Use PCI extension BIOS header only for PCI cards, all others use legacy
extension BIOS header.
+ Klaus Espenlaub contributed various cleanup patches to the code. Also
introduced Rainer Bawidamann's code, see next paragraph.
+ Rainer Bawidamann contributed a Realtek 8139 driver.
+ Simplified rules for building .bin files, use -b of as86 so we
don't need ld86 or objdump86 now. But later found that a fixed as86 is
required. So supply preassembled binaries. The keen hackers can get the
fixed tools.
+ Georg Baum contributed a Schneider & Koch G16 driver. Only the
32 bit version works at the moment; even though the 16 bit version
compiles, it won't work because the current code assumes flat memory
addressing. Anybody who needs the 16 bit version should feel free to
fix it.
+ Reduce size of ROM image loaded by floppyboot.bin from 64kB to 32kB
for a slight speedup in loading. None of the images are even 32kB anyway.
+ Updated some of the documents in doc/sgml.
+ Klaus Espenlaub sent in a totally revamped start32.S, using the code16
and code32 directives in recent GNU as (so if this file won't assemble
maybe your as version is not recent enough). Also patches to the menu
handling code.
+ jluke AT deakin PERIOD edu PERIOD au sent in a fix for the WD/SMC8013
long ago which I finally got around to verifying.
+ start16.o and start32.o are supplied for those people who have problems
compiling start*.S with as/as86.
Released as Etherboot-4.2.0
+ One line fix to 3c509b by Greg Beeley for Wake-On-LAN support.
+ Added patches by Klaus Espenlaub that I forgot.
+ Made AS_PSEUDOS not the default, assume that people have sufficiently
up-to-date GNU as. If not they can uncomment that line.
Released as Etherboot-4.2.1
+ Disable 3c509 after loading finished or port may be unusable.
+ Woops, forgot to up the version's last digit in the last release.
+ Stephan Bauer sent in a device ID for config.c for 21142 chip Tulips.
+ Ifdef out input overrun recovery code (it's really only needed for
NE2000s) and use SHMEM by default for 3c503s to bring the ROM size down
below 8kB.
+ Added code to start32.S to detect < 386 and exit so it doesn't hang
the computer. Doesn't print a message yet.
+ Changed README.sgml to recommend that TFTP use a separate directory
from NFS, /tftpdir. Added sample configuration file for DHCPD and caveat
about the name of the root directory when using DHCPD.
+ Revamped atnetboot.sgml: use mtools most of the time, write about a
few example applications.
+ Quick Perl script for converting bootptab to dhcpd.conf.
Released as Etherboot-4.2.2
+ Forgot to put new version of src/start32.o. Not urgent though, the
extra code only guards against Etherboot/32 being executed on < 386.
+ Supply version preassembled start32.o with ANSIESC and FLOPPY defined
for those with a deficient as. Define dummy handleansi routine in
ansiesc.c so that it will still link even if this start32.o is used.
+ Edited *.asm so that they can be assembled by either as86 (ELKS version)
or nasm.
+ Changed Makefile so that one can choose between no as86, as86 or nasm.
+ Added Mark Burazin's conditional code for Compex RL2000 PCI NIC.
+ Increase delay during probe phase to 10ms as 1ms is too low for some
3c509 boards. Donald Becker's Linux driver hints that > 2ms is needed
to be safe. Also call t509_disable in case board was active.
+ Update README.sgml date and version.
Released as Etherboot 4.2.3.
+ rtl8139.c: Reduce the number of transmit buffers to reduce footprint.
Remove polling loop in *_loop(), caller already does the looping.
+ main.c: Fix code indentation in bootp().
+ Small corrections to documentation.
Released as Etherboot 4.2.4.
+ Matthias Meixner found a longstanding bug in rtl8139.c where it was
testing the wrong bit for the existence of a packet in the buffer.
+ Added paragraph to documentation about caveats for hosting NFS root
on a different architecture.
Released as Etherboot 4.2.5.
+ Updated mklnim for RH6.0 which uses a different floppy image and
requires 'network' to be appended to kernel parameters.
+ Reversed sense of #ifdef DHCP_SUPPORT to #ifndef NO_DHCP_SUPPORT and
so forth, i.e. the default is with DHCP support.
+ Suggest reducing options for rtl8139 driver to minimise footprint in
release notes.
+ Jim McQuillan provided changes to support the SMC1211, which uses the
RTL8139 chip.
+ Changed lret in start32.S to int $0x19 so that it doesn't depend on
the return location being there.
Released as Etherboot 4.2.6
+ Succeeded in booting FreeDOS with the kernel in the tagged image rather
than on the ramdisk, i.e. the boot process jumps directly to the kernel
in memory. The utility is mkfreedosnbi in contrib/.
+ Additions to the documentation.
Released as Etherboot 4.2.7
+ Matt Hortman pointed out that the BIOS clock value returned by INT1AH
rolls over at midnight, causing delay loops that cross midnight to
fail. Fix was to keep track of midnight crossings in currticks so that
currticks' return value is monotonically increasing.
+ Added paragraph to documentation about editing PCI vendor and device
IDs in Makefile if needed.
+ Merged in FreeBSD support code supplied by Doug Ambrisko. Thanks!
Released as Etherboot 4.2.8
+ Cleaned up the FreeBSD support in osloader.c. Symbols to use in Config
are to select image type, not FreeBSD specific now.
+ Added simple signature checking code in floppyload.asm in case somebody
forgets to append a ROM image or tries to load a non-ROM image.
+ Merged in 3c90x and multiple PCI bus support by Steve Smith. Thanks!
+ Included NT-Diskless-Terminal HOWTO by Pavel Tkatchouk.
+ Included snapshot of H. Peter Anvin's rewrite of tftp.
+ Combined tftp and tftpd directories, and touched up Makefile to reflect
normal Linux install directories.
Released as Etherboot 4.2.9
+ NT-Diskless-Terminal HOWTO renamed to Diskless-From-NT.
+ One line fix to mknbi-dos to recognise FAT16 filesystems as legal.
Updated first.S in mknbi-dos so that it can be assembled by nasm and is
also suitable for FreeDOS with the right define. Still backward compatible
with as86. Bug fix at line starting getnm3:.
+ Updated first.S in mknbi-linux so that it can be assembled by nasm also.
+ Locate bootp data block at 0x93C00-0x93FFF to free up 1024+ bytes in
[0x98000-0x9FFFF]. Etherboot/32 only, business as usual for Etherboot/16.
+ Patch from Attila Bog<6F>r to make CONGESTED a compile option for
TFTP_TIMEOUT. Also corrected spelling of his name in README.
+ Fixed start32.S to assemble correctly with gas version 2.95. Must
define GAS295 in CFLAGS.
+ Add contrib/3c90xutil containing a utility for handling 3c90x EEPROMs
in situ.
+ Update p910nd to 0.3. client.pl now checks if hostname is known and
uses more convenient routines from Socket module.
+ Moved the Flashcard directory into a separate package as it's of
limited interest.
Released as Etherboot 4.2.10
+ Fixed bug introduced in 4.2.10 in code for handling bootp extension
files.
+ Change in 3c90x.c so that it can compile under FreeBSD.
+ Patch to tulip.c from Nick Lopez to handle Macronix 98715 (Tulip clone).
Released as Etherboot 4.2.11
+ Prefer RFC1533_GATEWAY to giaddr for routing tftp packets.
+ Print out both relay address and gateway address.
+ Stored arptable ipaddrs in network byte order. Makes everything simpler
and we can get rid of convert_ipaddr. Now %I in printf and inet_ntoa
have to deal with NBO. We reduce the footprint by ~100 bytes.
+ Renamed setip to more standard inet_ntoa and change argument type to
suit, using in_addr.
+ Replaced bcmp by memcmp, bzero by memset, and bcopy by memcpy. Allows
us to use optimised versions in inline assembler.
+ Replaced OUTB and OUTW by outb and outw with arguments reversed.
Finally all the out macros are the same form as for Linux.
+ Replaced \r\n and \n\r in output strings with \n since putchar
now prints \r before \n. Then changed printf("\n") to putchar('\n').
Like Unix convention for strings now.
+ Got rid of test.c and Makefile rules connected with it.
+ Added patch to eepro100.c by Matt Hortman to correct PCI latency.
+ Merged in Marty Connor's ntulip.c. Now supports Macronix 98715 and
Linksys LNE100TX.
Released as Etherboot 4.2.12
+ Anders Larsen contributed mkQNXnbi, for generating tagged images from
QNX kernels.
+ Bernd Wiebelt contributed code to request vendor tags in DHCP.
+ Fixed more bugs introduced in 4.2.10 in code for handling bootp
extension files.
Released as Etherboot 4.2.13
+ Marty Connor reduced RTL8139 footprint by using only one transmit
buffer instead of 4. Now RTL8139 is reliable.
+ Moved initialised data declaration from ns8390.h to ns8390.c.
+ Contributed utilities for wake-on-LAN: wol.c (Bob Edwards) and wake.pl.
+ Makefile for 3c90xutil/romutil.c. -O is essential when compiling.
+ Happy year 2000!
Released as Etherboot 4.4.0
+ VIA-Rhine driver contributed by Paolo Marini. Footprint reduced by
Marty Connor.
+ Netgear FA310TX (Tulip clone, LC82C168 chip) support added by Marty
Connor.
+ Support for 3C905C added by Marty Connor.
+ mklnim updated to support SuSE 6.x also.
Released as Etherboot 4.4.1
+ New configuration file scheme to specify what ROMs are built.
+ Adam Fritzler contributed 3c529 (MCA version of 3c509) support in
driver.
+ Marty Connor wrote a version of 3c90xutil/romutil for 905C NICs.
+ G<>nter Knauf contributed a wake on LAN CGI script.
+ Notes in contrib/eepro100notes on how to flash the EEPROM.
+ Happy Australia Day, 2000-01-26.
Released as Etherboot 4.4.2
+ hwilmer AT gmx PERIOD de found a probe error in 3c507.c, shouldn't
mask memory size with 0xffffL, this fails with 64kB memory. Also
changed to use real-time-clock to timeout on initialisation of i82586
rather than relying on decrementing a variable (which is CPU speed
dependent).
+ James Pearson pointed out that ~ should be escaped as &tilde; in
vendortags.sgml. Also cleaned up the 8-bit characters while I was at it.
+ G<>nter Knauf pointed out that if ASK_BOOT is defined, then key input
echos twice. Also, CR doesn't select the default. Problem was that getchar
converts all \r to \n then main.c was testing against \r instead of \n,
and also that getchar() was echoing when it should leave it to the caller.
Deleted code from getchar() and made it a function with no arguments.
Also sent me a new version of mp-form.pl with mp-form.txt. Also suggested
the good idea that the gateway and relay fields not be displayed if they
are not used.
+ Bob Edwards sent in patches to ntulip.c to autodetect 100 Mb media
for 21142/3 NICs.
+ Okuji Yoshinori found a small bug in main.c: for (retry1 = 0; retry < ..
Don't know what effect it had.
+ Klaus Espenlaub sent patches which make the RTL8139 driver more
reliable, see notes in rtl8139.c.
+ Russ Nelson gave permission to release cs89x0 driver with Etherboot.
It's normally under GPL. Moved cs89x0 driver to src directory, removed
cs89x0.sgml.
+ Clarified copyrights of files in distribution.
Released as Etherboot 4.4.3
+ Klaus Espenlaub sent in some patches to overcome the 64K block rollover
problem in tftp.
+ Bob Edwards, Paul Mackerras and Marty Connor worked out fixes to
ntulip.c to handle 21142/3 Tulips properly.

with large tftp blocks which I missed putting in.
+ Small patch by Marty Connor to tulip.c to handle fast Tulips better.
+ Wrote small loader to load images from .com files.
+ Shusuke Nisiyama contributed a 3c595 (and may work for 3c590) driver.
Released as Etherboot 4.4.5
A major reorganisation by Klaus Espenlaub. Here are his notes, verbatim:
The biggest change is the almost rewritten Makefiles (both in src and in
doc - the one in doc is still reasonably simple). If you want to get
an overview - basically one Makefile now builds both /16 and /32 ROMs.
This involves quite a few make variables (similarly in Config), but it
should be mostly self-explaining. I also converted the suffix rules to
pattern rules, because it is the only way to keep the build directories
for /16 and /32 apart.
Generally all /32 code is compiled in bin32, all /16 code is compiled
in bin16, and the code that works for both is in bin.
The names (object files, images, but NOT the final ROMs) used during
the build process for some PCI cards have changed (especially lancepci
and nepci).
I eliminated the driver.a file by adding yet more ugly code to genrules.pl
(no, I'm not very proud of the code I added there - I hate perl, but
at least it works), which now generates all sorts of make rules and
dependency information. This eliminates the redundant recompile of all
other drivers if you specified a specific target at the make command line.
There are now automatic checks for the generated ROM size (3K safety
margin are used to allow for 1K BIOS EBDA and 2K stack). This should
avoid most of the cases in which the stack overwrites code and/or data,
causing strange crashes.
On to the real code - I rewrote both the ELF and a.out loading (the
blocksize is now properly handled for all formats), and now most of the
code is identical. Someone might want to merge the two. I verified that
both a.out and ELF FreeBSD loading still works by booting the FreeBSD
2.2.8 and 3.4 install kernels (the ELF kernel you gave me didn't work
for whatever reason). Actually I tested everything except NBI, but that
code is completely unchanged.
I eliminated config.h and created cards.h - just have a look and you
should get the idea. The PCI/ISA prototype matching hack is now buried
in there. All PCI drivers (and skel.c) have been converted to the new
include file.
The only file that is really new is nfs.c, which contains the code where
I started my journey.
The loader code is now merged into one file for both the normal and
compressed case. Some bugs have been fixed along the way (the normal
loader copied too much data, potentially crashing the machine). BTW: I
removed the block copy from comboot, because the first thing the loader
code does is - to copy the code to the right place. Also copying it to
0x80000 prevents compressed ROMs (though there is no way in the Makefile
to create such a beast). Also the stack changing code was wrong -
the overflow handling is missing: 0x9fxxxx-0x800000 is truncated to
fit in the 16 bit register, which is not quite what one would expect.
The stack pointer must be in the same segment, so for overflows just
load 0. Anyway, we don't need a new stack for 4 bytes (the return
address). Also the shifts won't work on an 8086/8088. The ROM segment
and length code is also done once more in loader.S. Finally the org
0x100 didn't work with my version of as86 - it prepended 256 null bytes.
Don't get me wrong - I see that comboot was just a quick and dirty hack.
It's now working...
I also fixed floppyload to read exactly the right amount of data (not
up to 65520 bytes more like the Linux code did) and ripped out some
unused code.
3c509.c: includes fixed, const added, static added, removed redundant code
3c90x.c: includes fixed, const added, shortened messages to save space,
made the transceiver selection bootrom fix optional (default: off),
updated 3c90x.txt
ansiesc.c: de-tftpified (now uses "download")
config.c: moved the driver prototypes to separate file, added a few const
cs89x0.c: ansified, const added, fixed timeout handling
eepro100.c: includes fixed, const added, static added, USE_INTERNAL_BUFFER
hack, passing globals as a parameter removed, timeout handling fixed,
comments fixed
epic100.c: comments fixed, const added, static added, USE_INTERNAL_BUFFER
hack, removed unused variables, changed debug code to use macro instead
of variable, allow broadcasts to be received (after all how did it
work before???)
etherboot.h: dual/serial console "cleanups", added NFS support, fixed
INTERNAL_BOOTP_DATA for pathologic cases, removed prototype within comment
(how did that end up there?), moved prototypes for config.c code here,
added consts all over the place
floppy.c: added static, changed cleanup code
floppyload.S: renamed from .asm
genrules.pl: I didn't write this :)
i82586.c: fixed includes, added const
lance.c: fixed DMA for PCI cards, removed leftovers from Linux driver,
USE_INTERNAL_BUFFER hack
linux-asm-io.h: added prototypes
linux-asm-string.h: added prototypes
loader.S: renamed from loader.asm, more comments see elsewhere in
this mail
loader.inc: removed
main.c: includes fixed, static and const added, Etherboot/32 now prints
relocaddr, hooks for NFS support, drain the Rx queue in some strategic
places (after sleep), changed interface to await_reply: timeout handling,
new cleanup code
misc.c: ansified, twiddle code changed, strcasecmp enabled for
Etherboot/16 (smaller than the 16 bit libc version), clear A20 before
kernel is started (only for NBI), dual console fixes, removed bogus
comment about interrupt enabling using iskey()
nic.h: include guard added, added const
ns8390.c: fixed includes for PCI version, added const, ansified, renamed
internal functions
osdep.h: removed #include <asm/byteorder.h> - probably all #ifdef
__linux__ and __FreeBSD__ may be removed now.
osloader.c: see elsewhere in this mail. removed loads of debugging code.
otulip.c: removed unused variables, USE_INTERNAL_BUFFER hack, ansified,
added const
otultip.h: added const
pci.c: fixed signed comparison
pci.h: include guard added, const added
rtl8139.c: static added, const added, globals are no longer passes as
parameters, fixed probe loop
serial.S: removed the Makefile hack to calculate the divisor and replace
it by a CPP hack
sk_g16.c: added static/const
skel.c: updated
smc9000.c: fixed includes, added const, fixed timeout, removed unused
variables
start16.S: changed stack pointer reloading
start32.S: cleaned up GAS295 support, fixed CPU detection, fixed memsize
for > 64MB, added basememsize()
tiara.c: fixed includes, added const, removed unused variable
tulip.c: fixed includes, added const, decreased oversized frame tolerance,
USE_INTERNAL_BUFFER hack, converted to C comments, fixed prototypes,
removed unused variable
via-rhine.c: fixed includes, converted to C comments, removed unused
functions, fixed timeout, USE_INTERNAL_BUFFER hack, removed unused
variable, const added
lzhuf.c was modified not to output ':' characters, because I find it
useful to search for them in a make log to spot all error messages.
Finally all symlinks have gone
I fixed sgml/vendortags.sgml (maybe it's more a workaround): sgml2txt
didn't like the ~~' sequence and ignored a whole line, making the .txt
file incomplete. Also freebsd.txt was converted to sgml.
My standard patch to netboot-0.8.1/configure (to remove the "unknown") is
again in place - how is this file created? By hand? I added serial/dual
console support to mknbi-linux.
Oh, and something I almost forgot: Etherboot now works under VMware.
VMware has a rather large EBDA (3K instead of 1K like most other
BIOS versions), so one might have to sacrifice a few nifty options.
Note that the Makefile check cannot detect this - maybe we should add a
runtime check, too? One thing that doesn't work with VMware is the "Boot
Local" stuff - it's not terribly useful if you have to boot from disk,
but it shouldn't crash the machine (I've seen several triple faults,
depending on RELOCADDR and the stack usage). I tracked it down to the
fact that VMware crashes on int 0x19 if the memory area 0x98000-0x9f3ff
is overwritten. If one changes RELOCADDR to 0x8f000, everything works
nicely. Someone should report the bug to VMware. Also proper boot ROM
support should be added to VMware and they should upgrade the virtual
card to 100Mbps (don't laugh - they limit the bandwidth to 10Mbps even
if you have a real 100Mbps card!). Maybe one could even use the flash
utility for the recent AMD PCnet cards...
Released as Etherboot 4.5.5
+ More fixes from Klaus Espenlaub, based on bug reports by Doug Ambrisko
and others. Small cleanups in tulip.c. He also added a BACKOFF_LIMIT
parameter to the exponential backoff for retry intervals.
+ Christoph Willing sent in a fix for PCI NE2000s which forces 16-bit
transfer mode for PCI. This might make it work on some PCI NE2000s that
failed before, please test if you can.
+ Moved commercial links off main web page into web page of its own.
+ Merged in TRY_FLOPPY_FIRST code from <as AT bart PERIOD nl>.
Released as Etherboot 4.5.6
+ Frank Mehnert spotted a bug in tulip.c where the sole transmit buffer
was not tagged as the last one in the chain.
+ Hacked serial.S to check if a serial interface is present and to disable
the routines if not, so that Etherboot does not hang on a machine without
a serial interface, even if the option has been compiled in.
+ Wrote mkromnbi for making a network bootable image from a ROM image
(for using Etherboot to test another Etherboot driver).
+ Krzysztof Halasa found a small bug in nfs.c in the handling of BOOTP
extension files.
+ Some instructions on adding Etherboot to a main BIOS were contributed
by Dirk von Suchodoletz.
+ Some commentary on cbrom.exe versions posted by Rapp Informatik Systeme
GmbH to the Netboot mailing list included.
Released as Etherboot 4.5.7
+ Patrick Auge pointed out that -DT503_SHMEM option should be not used
by default, as the comments say.
+ Heinrich Rebehn pointed out that the documentation needed to be updated
for the new bin32 and bin16 prefixes for targets.
+ Christoph Plattner found that node_addr in struct nic should be unsigned
char * or problems occur in the handling of the MAC address in cs89x0.c.
+ Greg Hudson pointed out that inet_ntoa is misnamed, it should be
inet_aton.
+ Vsevolod Sipakoff suggested that the probe address list for NE2000
should match that of Linux. Done, with the deletion of 0x360 which often
conflicts with the parallel port at 0x378.
+ Created mknbi, a Perl utility that replaces mknbi-dos, mknbi-linux,
mkfreedosnbi, and mkromnbi. Removed mk{freedos,rom,elks}nbi/ from
contrib/. (ELKS has its own tagged image creation method now.)
+ Removed obsolete/ from contrib/.
Released as Etherboot 4.5.8
+ Some small enhancements to mknbi. Merged in disnbi and mklnim. Changed
version to 1.0.
+ netboot-0.8.1 directories distributed separately now.
Released as Etherboot 4.6.0
+ Nick Lopez discovered that the Davicom 9102 is Yet Another Tulip Clone
and a few appropriate initialisations will make it work.
+ Matthew Reimer sent in patches for contrib/3c90xutil.c/bromutil.c to
compile and run under FreeBSD.
+ Krzysztof Halasa found that the number of buffers in epic100.c needed
to be raised to 2 each for operation at 10 Mb for the PCI EtherPower
9432B-TX using the SMC 83C171.
+ Klaus Espenlaub fixed the root path handling in main.c, it wasn't
requesting option 17 in DHCP. Also removed one prototype warning in
tftp().
+ Daniel Shane sent in code for for adding identifiers to a DHCP request,
using a user specified DHCP option. The patch is in contrib/dhcpid.
+ Bug fix in mknbi-1.0 for the ipaddrs=rom option, warnings about badly
formed specification to ipaddrs= or unresolvable names.
Released as Etherboot 4.6.1
+ Stuart Lynne sent in patches to allow - to mean reuse kernel filename
in menu specifications. Also fixed DHCP request to ask for tags 129 and
130 (Ken added this), as the mknbi man page promised.
+ Fixed URL for Richard Ferri's LUI.
+ Added URL for Gregory R. Warnes' ClusterNFS.
+ Changed RFC2132_MAX_SIZE option in main.c to allow maximum size DHCP
replies.
+ Matthias Schniedermeyer submitted an optional feature to use numbers
instead of letters for bootmenu entries.
+ Brought some FAQs up to date with mknbi-1.0.
+ Wrote perl script mklrpnb for making netboot image from Linux Router
Project floppy. Tested on Coyote Linux (based on LRP).
Released as Etherboot 4.6.2
+ Re-enabled tulip.c:tulip_disable() code.
+ Minor fix to SHOW_NUMERIC code in bootmenu.c.
+ Minor spelling corrections to vendortags.sgml.
+ andreas.kabel AT slac PERIOD stanford PERIOD edu pointed out that to
be RFC951 compliant, the broadcast BOOTP request near line 705 of main.c
should use port BOOTP_CLIENT and thus stand a better chance of going
through firewalls.
+ Christoph Plattner found that the 16 bit bus width fix for NEPCI cards
introduced in 4.5.6 breaks operation for other NEPCI cards. So now the
#define symbol is NS8390_FORCE_16BIT, to be used when the NIC requires
16 bit bus width but Etherboot guesses wrong. This needs to be fixed
later to autodetect adapter bus width.
+ Shusuke Nisiyama sent me the PCI IDs for 3C595 NICs so that ROM images
could be generated for them.
+ Jim McQuillan sent in modifications to tulip.c to reject bad packets.
+ Klaus Espenlaub suggested changing the filename substition macro in the
IDENT16 and IDENT32 strings to $(@F) so that only the filename portion of
the pathname is inserted. Otherwise the contributed romid program breaks.
+ Added author ident and copyright status to contrib/bin2intelhex.c.simple
at Rogier Wolff's request.
+ G<>nter Knauff sent updates to romid and mp-form.
Released as Etherboot 4.6.3
+ Marty Connor contributed patches to tulip.c to support the LinkSys
LNE100TX v4 NICs.
+ Added rmrd.com to mknbi-1.0 directory.
+ Added experimental changes to allow RELOCADDR to be changed to 0x88000
to avoid Disk On Chip drivers. See RELNOTES and Makefile for details.
Released as Etherboot 4.6.4
+ Chris Johns found a long-standing bug in first-linux.S. ES would
sometimes != CS, making the ramdisk moving fail.
+ Made --harddisk work for mknbi-fdos.
Released as Etherboot 4.6.5
+ Bug in mknbi-dos, last sector omitted in ramdisk image.
+ Use ceil() for computing number of rootdir sectors.
+ --harddisk now works for mknbi-dos also.
+ Should work on FAT16 partitions now.
+ New driver for Winbond W89C840 by Igor V. Kovalenko.
+ Modification to loader.S by Steve Smith for some PCI BIOSes that don't
handle INT19H well.
+ Small bug in osloader.c, j not defined in two places if DELIMITERLINES
defined.
Released as Etherboot 4.7.6 (developmental)
+ All the changes from 4.6.5 to 4.6.6 back propagated except for the
loader.S change.
+ Removed -nostdlib from ld flags. Seems to be a vestige from when we
were calling gcc as it's not an ld option.
Released as Etherboot 4.6.6
+ Contributed one-line patch to allow booting from SCSI disks also (sd).
+ Grzegorz Jablonski sent in a fix for long-standing bug in loader.S that
prevented booting on some BIOSes.
+ More updates to documentation.
Released as Etherboot 4.6.7
+ Rick Kennell pointed out that there is another place in main.c where
the DHCP request is sent with a source port of 0, which may not elicit
replies from some DHCP servers or pass gateways. Changed to
BOOTP_CLIENT.
+ Depca driver finally works.
+ Changed unsigned int len; to int len; in 3c595.c transmit routine
which was generating a warning from gcc.
+ Removed warning about ljmp indirect without * in start32.S by putting
in the *. Checked that generated code has not changed by comparing
binaries. Later: But only for gas 2.9.5 and above, gas 2.9.1 doesn't
like *.
+ Wanted to do the same for the lcall's in pci.c but discovered that
gas 2.9.1 chokes on *, and as I don't want to introduce more #ifdefs
into pci.c, we'll just live with the warnings until gas 2.9.1 is dead
or the incorrect syntax is rejected by a current gas release.
+ Reversed #define so that GAS291 indicates gas 2.9.1. Rationale: gas
2.10 probably behaves like gas 2.9.5 so the default should be the new
behaviour.
+ NI5010 driver finally works. Weird NIC, has only 2kB memory on board
so if you don't switch to the receiver immediately after transmitting
you will lose the reply packet. (This is a very ancient board, I was
doing the driver for kicks.)
+ Implemented a low-overhead timer routine for implementing timeouts in
drivers. This timer should be used instead of hacks with integer loops
(which are CPU speed dependent) or calling currticks(), which has
relatively high overhead because it reads the BIOS timer, and has a
resolution of only 1/18th of a second. Timer 2 of the 8254 timer chip
can be loaded with an unsigned 16-bit value that will be decremented at
about 1193 counts per ms (constant TICKS_PER_MS in timer.h). So the
maximum timeout that can be implemented with a single call is about 54
ms. Call load_timer(u16) to load and start the timer (0 == 65536). Call
int timer2_running() to check if it is still active. timer2_running can
be interleaved with other tests, e.g. on the NIC hardware registers.
When the timer runs down to 0, it will return 0. If you just need to
delay a short time, call waiton_timer2(u16) to load and delay that many
ticks.
+ Removed slowdownio() from sources. It's called in only one place and
is followed by a call to currticks() which will result in a large delay
anyway. It's also not clear if the strategy in slowdownio (a couple of
local jumps) will even work on fast CPUs with instruction caches.
+ Removed support for %i (alias for %d) in printf. Nobody uses it, if
they do they should just edit the format string to use %d, and removing
it means one less non-standard format in printf; we have %X, %b and %I
as it is.
+ Simplified currticks() by accessing BIOS variables directly instead of
calling timeofday BIOS interrupt.
Released as Etherboot 4.6.8
+ I'm pissed off with the inconsistency between gas 2.9.1 and gas 2.9.5
re ljmp * (indirect jump). Some assemblers claiming to be 2.9.5 dislike
the * (RH6.2's is one). I'm going to just make it ljmp and live with the
warning message until the gas 2.9.1 syntax is totally dead.
+ Various fixes from Klaus Espenlaub: Fix for NFS booting from *BSD
platforms, fix for Lance driver, interrupt was being turned on, fix for
serial.S and code cleanups.
+ Paul Robertson of Locsoft found that if the top half of %esp contains
garbage just before the first call to real_to_prot in start32.S, it can
affect booting on some BIOSes. Inserted andl to clear top half.
+ Sleep for 2 seconds after failure to load file to avoid pounding the
server if the file does not exist and thus shutting down the tftp
service (inetd has rather poor rate controls).
+ Shredda of gmx.de reported a discrepancy between the Macronix MX98715
device IDs used in pci.h and NIC. Marty Connor has ruled that the id in
NIC is a typo. If booting works from floppy but not from ROM, this may
be the reason.
Released as Etherboot 4.6.9
+ Oops, a brown paper bag bug in start32.S. Forgot that the currticks()
needs interrupts enabled to work. Calling the BIOS allowed interrupts to
happen by going into real mode (interrupts are disabled in protected
mode). So inserted prot_to_real and real_to_prot pair inside
currticks().
Released as Etherboot 4.6.10
+ Marty Connor and Gary Byers of thinguin.org contributed a LILO prefix
file that makes the Etherboot image look like a Linux kernel to LILO and
thus bootable from the LILO prompt.
+ Ifdefed out code in mknbi that falls back to the tftp directory for
root-path. The result is that the options passed to the kernel specifies
the tftp directory as nfsroot even if there is no root-path option in
the DHCP or BOOT server configuration. This interacts badly with recent
Linux kernels which actually pay attention to the root-path handed down
and use that as nfsroot. People who were expecting the diskless kernel
to use the default /tftpboot/<name of client> as nfsroot would have been
surprised to find it trying to use the tftp directory (which often
happens to be /tftpboot, although I recommend that it be different, to
improve security).
+ Eric Biederman found an off-by-one bug in the ELF loader.
+ Christoph Plattner pointed out that the comments for COMCONSOLE in
Config are wrong, the serial port is at 3F8, not 378.
+ A couple of updates to wol.c and wake.pl by G<>nter Knauff.
+ The Davicom 9009 and 9102 driver was contributed by Sten Wang of
Davicom. It will be merged into tulip.c later.
+ Implement eepro100_disable. There have been reports of memory
corruption after Etherboot has handed over to the booted image due to
the live controller.
+ Matt Hortman reported a new Intel NIC, 82559ER, with different IDs.
Added to file NIC.
+ Ranjan Parthasarathy reported another Tulip clone from ST Micro with
different IDs. Added to file NIC.
Released as Etherboot 4.6.11
+ Stefan Lesicnik sent in a report from Intel which explains what is
probably wrong with the PnP header. BEV should point to the mainline
vector, not to the part that installs the INT19H vector.
+ Hopefully finally fixed DHCP option limit problem. It was requesting
large packets but not parsing them fully due to the length limit passed
into decode_rfc1533(). Thanks to shredda for testing this.
+ Added the # modifier to printf, it prefixes 0x to %x and %X making
printf formats shorter throughout. 0x%[xX] changed to %#[xX] in lots of
files. Now if only I could make b,x,X the standard hhx,hx,x and get rid
of I.
+ Andreas Neuhaus provided patches for multiple rx buffers for lance.c
which made it work again with VMware.
+ Perl script to convert floppyfw floppies to netbootable images.
+ Marty Connor made some small changes to liloprefix and Makefile to
make the LILO images SYSLINUX bootable also.
+ Make the default return value for _poll in skel.c 0 so that when
driver writers implement _transmit first, it will not hang on garbage
return values from _poll when it's called to flush the input queue
before the first transmit.
+ EEPRO/10 driver now works. <20>s timer routines came in useful.
+ Anders Larsen sent in a patch to 3c90x.txt which makes it clearer.
+ Added more stuff to the documentation.
+ Fixed bug in mknbi that always did the equivalent of --ipaddrs=rom
no matter what. Also removed undef from my variable list in TruncFD.pm
so that it won't have problems with Perl interpreters.
Released as Etherboot 4.6.12
+ Jim McQuillan sent in a patch for first-linux.S where it was assuming
the argument in tag 129 (additional parameters) is a null terminated
string, when it's a length counted string. A new routine, addkarg was
created to handle this.
+ eepro100 should handle newer NICs with 256 byte EEPROMs now. This
includes the onboard NICs on some motherboards, see file NIC. Thanks to
Stephan Lauffer for helping with the fixes. WARNING: This code may have
a bug that causes the onboard EEPROM to be corrupted. We believe we have
found and removed the bug but please proceed with care.
+ DHCPDISCOVER was sending out one byte too many for PARAM_LIST.
+ In DHCPDISCOVER send "Etherboot" in VENDOR_CLASS_ID option (60). Will
add code later to check for "Etherboot" in vendor encapsulated options.
+ Used <20>s timer routines in 3c509 for more accurate timing and hence
better hardware detection. Use COMMAND_IN_PROGRESS bit to detect
transmit complete instead of waiting for a fixed amount of time. Get rid
of eth_vendor and associated tests, it doesn't serve any useful purpose
since the driver was modularised long ago and the 3c509 detection status
is stored outside of the driver now. Got rid of some unused global
statics in 3c509.c, leftovers when the drivers were monolithic. Wait 2
seconds after enabling TP interface to give it time to come up. This
allows us to get rid of T509HACK in main.c.
+ Get rid of eth_vendor and associated tests in cs89x0.c, same reasons
as for 3c509.c.
+ Moved the rest of the VENDOR_ and FLAG_ defines into ns8390.h, as
ns8390.c is the only file that uses them now.
+ Use lower 32 bits of node address + current time for xid (network byte
order). More likely to be distinct from other clients than just the
current time, which is similar for all clients booted at about the same
time.
+ Support for 16-bit code has been removed. XTs and ATs are pretty much
dead now and in fact many Etherboot/16 drivers have been broken for a
while but nobody noticed. This should make some of the code easier to
maintain. If you really wanted 16 bit support, use an older version of
Etherboot, maybe 4.4 or something like that, not sure when things
started breaking for 16 bit mode.
+ Should not store IP and UDP headers at BOOTP_DATA_ADDRESS. Redefined
bootp_t without IP and UDP headers. Now requested size of bootp packet
matches storage available. Do not add sizeof(iphdr) + sizeof(udphdr) to
bootp pointer in start32.S:xstart now. start16.S:xstart was broken
because it did not do this addition but nobody noticed.
+ Removed array kernel_buf, saving 128 bytes and replaced with
KERNEL_BUF, a pointer into the bp_file of the bootp_reply structure at
BOOTP_DATA_ADDR. Note: this depends on the server not sending Option
Overload which would use the sname and file fields for options, but we
don't request this option so it shouldn't. Removed char *kernel,
instead check KERNEL_BUF[0] just before booting and if null, use
fallback filename. (This is needed for future extensions to booting
protocol.)
+ Define a shorter tftpreq_t type for making requests instead of using a
full sized tftp_t packet to reduce stack usage.
+ Defined macros for htonl/htons/ntohl/ntohs for cases where the operand
is a constant, saving a function call.
+ Started on first32.c, a protected mode 32-bit version of
first-linux.S, which should be far easier to read and maintain. Will
boot basic Linux kernels correctly but doesn't handle ramdisk or
kernel arguments yet.
+ Updated nfs-swap documentation in contrib/nfs-swap to point to
Claus-Justus Heine's new web page.
Released as Etherboot 4.7.13 (development)
+ Added more IDs for eepro100 variants taken from the Linux 2.2.18
source. Should handle the EEPROM properly now, a few defines were wrong
in 4.7.13. Loop counter timeouts in eepro100.c replaced with hardware
timeouts. Don't loop waiting for packet in _poll, return 0 immediately.
+ first32.linux works. Does kernel arguments and ramdisk but doesn't do
appended parameters from menu selections, which should be replaced by a
more elegant menu scheme anyway. Needed gateA20 routines in
mknbi-1.1/first32.c otherwise cannot access extended memory.
first32.linux should be able to handle memory > 64 MB, which the old one
couldn't. Support for first32pm call protocol added.
+ 3c595.c changed to use hardware timer for delays. Transmit routine
waits for a fixed period after transmitting. Changed to check
S_COMMAND_IN_PROGRESS bit. It also contains some of the same unused
variables as 3c509.c and mentions 3c509 in some comments. Cleaned up.
+ Hmm, how come this wasn't fixed long ago? Should discard BOOTP/DHCP
replies that are not to broadcast or own MAC address. I guess xid caught
practically all of the non-matching packets. (Later: Actually the NIC
should filter out packets we don't want, but leave test in anyway, it's
the last test.)
+ Removed last vestiges of ETHERBOOT32 and ETHERBOOT16.
+ ETHER_ADDR_SIZE => ETH_ALEN, ETHER_HDR_SIZE => ETH_HLEN,
ETHER_MIN_PACKET => ETH_ZLEN, ETHER_MAX_PACKET => ETH_FRAME_LEN. More
Linuxy and therefore more familiar to programmers.
+ Cleared up confusion with 60/64 and 1514/1518 for minimum and maximum
frame sizes. Practically always the right numbers are 60/1514, except
that some chips count the FCS in the receive length, then we have to use
64/1518.
+ Make __swap32 and __swap16 inline routines available globally as
swap32 and swap16. eepro.c can use swap16 instead of making up one.
+ Make aui field in nic.h an int since it will be padded to a longword
boundary anyway and call it flags so that other drivers can use it for
their own purposes. Currently only 3c503 uses it to indicate AUI xcvr.
+ Make sprintf return number of characters written instead of a pointer
to the last char written to be more consistent with standard C.
Released as Etherboot 4.7.14 (development)
+ Thanks to Mark VandeWettering for the start of HomePNA (networking
over phone lines) support for the AMD 79C978.
+ Bug fixed in first32.c handling of (ip|nfsroot)=X where X is not rom.
+ first32pm.linux works. No need to go into real mode to call first32pm
and then it goes back to protected mode. Paves the way for extension
routines to Etherboot. Implement program returns to loader flag in
header field. Added option to mknbi to specify this.
+ first32*.linux: Check tag 128 present and correct before appending tag
129. Also tag 129 should be appended to parameters before substitutions.
+ Merged cleanup_net into cleanup since they are always called together.
+ Floppy booting doesn't need to be passed BOOTP_DATA_ADDR.
+ Clean up variables associated with tagged image loading in osloader.c.
Released as Etherboot 4.7.15 (development)
+ Duplicated 3c900 PCI IDs under 3c595 as some NICs apparently detect
and work with the 3c595 driver but not the 3c90x driver, according to a
report from Dirk Pfau. (The 3c90x series has two modes of operation,
programmed I/O mode descended from the 3c509, good only for 10 Mb
operation, and bus mastering mode, essential for 100 Mb operation. For
network booting, either mode is acceptable.)
+ Removed auto from kernel parameters; it's the default already.
+ Use hardware timer instead of loop counter for transmit timeout in
3c90x.c.
+ Define a jmpbuf type for setjmp and longjmp. Trim size to 7 longs,
that's all that's needed. Standardise the return values from longjmp:
-2: loader error, -1: timeout or ESC, 0...: various meanings to
Etherboot main loader.
+ Ansify function headers in bootmenu.c.
+ Make _int10 return ax | (bx << 16) as result so that these can be
accessed more efficiently in the following statements.
+ Make handleansi take unsigned int instead of unsigned char as
argument, otherwise extra code will be generated to handle this
according to ANSI rules. (Quite significant saving of 55 bytes.) Rename
it ansi_putc for clarity.
+ Prefix getc, putc and ischar with console_ to make things clearer and
to avoid confusion with the Unix getc, putc.
+ Add menu as a target to mknbi. Started source code for menu extension.
Successfully transferred control to menu at 0x10000 and back. ANSI
colour controls work, at least. Return end needs more work.
+ Started on ELF support in mknbi.
Released as Etherboot 4.7.16 (development)
+ Added atftp 0.2 (ftp://ftp.mamalinux.com/pub/atftp/) to contrib/.
Supposedly contains a tftpd that runs multithreaded, which may help
people having problems with *inetd shutting down tftpds that spawn too
fast.
+ Added a few more Tulip entries to config.c and NIC, not all of them
have been confirmed working.
+ Got ELF format creation in mkelf-linux working now. At least one empty
section header is required to make a valid ELF file.
+ Added code to support non-MULTIBOOT ELF when IMAGE_ELF is selected but
IMAGE_MULTIBOOT is not. Booting from images created by mkelf-linux
now works!
+ TAGGED_IMAGE is now not always selected. It's just the fallback if
none of TAGGED_IMAGE, AOUT_IMAGE or ELF_IMAGE is selected. Therefore you
must explicitly select TAGGED_IMAGE if you want it, and you have
selected AOUT_IMAGE or ELF_IMAGE. Startup banner line displays all
image formats accepted.
+ exit() in mknbi/start32.S should copy argument to %eax first.
+ Images with 0xAA55 in bytes 510-511 are no longer accepted, which
should reject invalid formats now, e.g. Linux kernel images, which have
a boot sector in the first block. Strictly this does not conform to the
original netboot spec by Jamie Honan, which specifies that non-tagged,
linear images starting from 0x10000 are allowed, but that format is
pretty useless now. Any decent loading scheme needs a roadmap to the
blocks in the downloaded file, which is what tagged, a.out, or ELF
images provide in the header. Q: What is config_buffer in main.c for?
Nothing else seems to use it. Is it a relic of non-tagged images?
+ Clean up lots of obsolete prototypes in etherboot.h. Ansify lots of
function headers in main.c. Make lots of functions and variables in
main.c static. Make bootmenu.c:getoptvalue() static.
+ Simple external menu program works!
+ More documentation cleanup, notably editing the compile options to
match what has been done.
Released as Etherboot 4.7.17 (development)
+ Marty Connor did it again! He found a long standing bug in the PnP ROM
header which caused it not to be recognised by BIOSes. Now Etherboot ROM
images are PnP compliant. I hacked makerom.c to fill in the offset of
the ident string for the device string so that the BIOS can even print
out "Etherboot" and the device ident on boot up.
+ Made demo menu program a bit more elaborate with timeout.
+ Igor V. Kovalenko fixed the Winbond W89C840 driver to use the hardware
timer instead of CPU counter loops. Now none of the Etherboot drivers
rely on CPU speed dependent loops.
+ Small fix to contrib/p910nd.c to not use getprotobyname which requires
libnss_files.so, which may not be installed in all environments.
+ Small change to contrib/mkffwnb to allow the user to choose ELF format
(by editing one line) instead of tagged format.
+ Patch to atftp-0.2 to make it accept a filename if the directory is a
prefix of the filename. This is needed so that valid absolute pathnames
will work. Patch sent to atftp authors.
+ Added support for filtering out replies which do not include a Vendor
Class Identifier of "Etherboot" in the Vendor Encapsulated Options. This
can be used to select only the DHCP servers which we want to get
addresses from and reject the rest. Select the compile option
-DREQUIRE_VCI_ETHERBOOT. This requires ISC DHCPD 2 or 3 AFAIK. (It's
not documented in DHCPD 2, but it works.) Other DHCP servers may support
VEO. (It's a RFC2132 option.)
+ Jim Thomas suggested a way, other than creating /fastboot, of
preventing fsck from running on NFS root, ln -s /bin/true
/sbin/fsck.nfs. Not verified but should work. Added to documentation.
Released as Etherboot 4.7.18 (development)
+ Pavel Tkatchouk verifies that lance.c can handle PCnet-FAST III
79c973. Added a new entry to lance.c and NIC. NIC entry not verified
yet.
+ Enhanced disnbi to decode ELF images too.
+ Arrgh! There are old BIOSes that rely on the wrong order of the bytes
in the device identifier in the PCIR and PnP structures. Wrote a Perl
program swapdevids.pl to swap these bytes. Apply this to image file just
before programming the EPROM.
+ Marty Connor suggested that the specs state that for PnP ROMs the
unsuccessful return from boot should be int 0x18 rather than int 0x19.
Using int 0x19, selecting L for local device doesn't work. Fixes needed
in both loader.S and start32.S (get lret to work properly, instead of
doing an int 0x19 directly, involved saving ss and sp in real mode
instead of in protected mode).
+ Wrote a Perl program disrom.pl to display key structures of a ROM
image.
+ Added call to binmode() in various Perl utilities so they should work
under other OSes.
+ Added check in makerom.c to warn if 55 AA not found at start of image.
It seems some people don't read the warning not to use the Linux
supplied as86.
+ It seems Z is a recent addition to pack/unpack formats in Perl and
even a Perl as recent as 5.004 doesn't implement it. Change Z5 in
mknbi.pl and TruncFD.pm to a5 since we only need to compare it against
'FAT12' and 'FAT16'.
+ Some errors found in osloader.c in the #ifdef IMAGE_MULTIBOOT
sections. kernel should be KERNEL_BUF and union info should have
unsigned short s[256];. Also kernel -> KERNEL_BUF for IMAGE_FREEBSD,
obviously few FREEBSD users have tried compiling it.
+ Explain in docs that .com and .(lz)lilo images can be generated and
touch briefly on how to use them.
+ Donald Christensen contributed translations of floppyload.S and
loader.S to gas syntax. Currently they are in contrib/gassyntax/. They
potentially allow us to throw away as86 and/or nasm and use GNU tools
throughout, but I have to do some work on them: 1. I have to check what
versions of gas accept the syntax, the 16-bit mode in gas was a recent
enhancement; 2. I have to put back the #ifdef PCI_PNP_HEADER into
loader.S and also bring it up to date to the recent patches.
floppyload.S should be usable as is.
Released as Etherboot 4.7.19 (development)
+ Donald Christensen completed the translation of loader.S and all the
other .S files in the src directory that previously required as86 or
nasm. No more futzing around with precompiled versions. Yipee!
+ Luigi Rizzo contributed a slightly hacked FreeBSD loader that works on
floppy or hard disk. See boot1a.s for details. Makefile rules edited.
Targets renamed .dsk and .lzdsk to indicate they're not floppy specific
now. Documentation updated. I note that the loader is smart enough to
figure out exactly how many sectors have to be read.
+ Renamed comload.S to comprefix.S which describes it better.
+ mknbi tools split out into separate package for independent
development.
+ Use A32 instead of Z32 in unpack format in disrom.pl in case we
encounter old Perl versions (< 5.005).
+ Vendor Class Identifier string that's sent out is now of the form
Etherboot-x.y (13 bytes long).
+ Reduced size of ee_data in davicom.c to 32 bytes because we only need
to access the MAC address in bytes 20:25.
+ Changed type of formal arguments to pci.[ch] routines to unsigned int
except for the last argument, because in ANSI C parameter passing is
like assignment and extra dummy variables and code may need to be
generated if the formal argument type is not the the same size as the
actual argument that gets pushed on the stack. Not insignificant
overhead, reduction from 1853 to 1727 bytes due to change. Changed devfn
and bus members of struct pci_device to unsigned char to enforce limit
on type. Surprisingly this reduced the size further to 1667 bytes.
Probably the compilier could do more optimisations after the last
change.
+ Some drivers hardwired 0 for bus number in calls to pcibios_*
functions. Changed to pci->bus, which is set in scan_bus. Only
people with NICs not on bus 0 would have noticed.
+ Found a couple more old-style pre-ANSI C function declarations. Turned
on -ansi and -pedantic for kicks and fixed some non-ANSIness, e.g.
// comment in #define, text after #endif, casting memcpy arguments to
void *, using void * instead of char *. Some char declarations changed
to unsigned char.
Released as Etherboot 4.7.20 (development)
+ I changed my mind. I think the format in disrom.pl should be Z32,
otherwise it displays binary characters after the valid part of the
string. For people with Perl < 5.005, please upgrade.
+ Moved RELOC down to 0x94000. Turned on USE_INTERNAL_BUFFER by default.
Unless BOOTP_DATA_AT_0x93C00 is defined, use internal bootp strucutre.
This gets Etherboot out of the area just below 0x10000 and the area from
0x93C00-0x93FFF. DHCP packets can now be as large as the Ethernet
payload. Later on, first32.c and the parameter area could expand a bit.
In lance.c had to reduce RX_RING_SIZE (by reducing LANCE_LOG_RX_BUFFERS)
from 16 to 4 to fit the driver. I'd like to hear feedback from lance
users. Is 24kB of receive buffers really needed given that Etherboot
uses stop-wait protocols?
+ Doug Ambrisko sent in some patches for FreeBSD: a correction for one
typo I missed and changes to make compilation under FreeBSD easier.
+ Michael Sinz contributed patches to allow the FreeBSD loading code to
load debugging symbols also.
+ Marty Connor contributed a SiS900 driver. Also pointed out that if
ASK_BOOT <= 0, the prompt and read shouldn't even happen. Conditional
code reworked.
+ Split documentation into user manual and developer manual. Added
material.
Released as Etherboot 4.7.21 (development)
+ Preston Wilson pointed out that ds.internic.net should be replaced by
www.ietf.org in documentation URLs. Also RFC1090 should be RFC1094
(NFS).
+ Marty Connor pointed out some broken links due to the split in
documentation. Also comments don't match code in lance.c for change just
above. Also passed on a bug found by a user of rom-o-matic.net where
tftp was not defined when ANSIESC was defined. My mistake, I made it a
static function when it needs to be exported to ansiesc.c.
+ Christoph Plattner found that the Etherboot startup messes up the
flags while testing for a 386+. This doesn't affect Etherboot but it can
cause the loaded operating system to crash. Fix: pushf before and popf
after the CPU model testing.
+ Jean-Jacques Michel contributed patches to the via-rhine.c driver to
make it work for the VT6102 model as used on some DFE530-TX Rev.A3 NICs.
+ Luigi Rizzo sent in a fixed boot1a.s that actually works on HDs now.
+ Stefan Furtmayr sent in a list of URLs to TFTP servers for NT. Added
to directory contrib/Diskless-From-NT.
+ Paul Whittaker contributed a HOWTO in HTML format on booting with NT
as the server. Added to directory contrib/Diskless-From-NT.
+ CJ pointed out that the advertised message size is > 1500 bytes.
Define MAX_BOOTP_EXTLEN so that the size of the structure matches the
Ethernet payload size.
Released as Etherboot 4.7.22 (development)
+ Reintroduce the old Via-Rhine PCI IDs into file NIC and give the
corresponding ROM images -old suffixes, in case some people are using
the old chips.
+ Peter K<>gel contributed patches to the SiS900 driver to make it work
for the SiS630e and SiS730s.
+ Charles Dobson pointed out that when booting from a PnP BIOS, the code
should not hook or restore the INT19H entry point. Put hooking code
inside #ifndef PCI_PNP_HEADER and changed entry point in PnP structure
from start19h to blockmove.
+ I have one report that gas 2.91 doesn't assemble loader.S because it
can't handle all the 16-bit code. Since the benefits of using gas for
all assembly code are great, and gas 2.95 has been out there for a long
time, I regretfully say to affected users: upgrade your tools. Otherwise
there may be a workaround by specifying the opcodes literally. I leave
it to interested parties to try. If you do this, put in an #ifdef
GAS291, naturally.
+ Updated contrib/tftp-hpa to 0.16 from ftp.kernel.org.
Released as Etherboot 4.7.23 (development)
+ Rename nepci entry in file NIC to rtl8029 to avoid giving the
impression that nepci will work for all PCI NE2000 clones. Make the
issue of PCI IDs in ROMs clearer in documentation, both in the
configuration and troubleshooting sections.
+ Tania Oka and Hyun-Joon Cha at about the same time found that
implementing the rtl_disable() routine in rtl8139.c stopped random
crashes in Linux later. It is important to disable the NIC after network
loading.
+ Implemented _disable() routine in w89c840, 3c90x and via-rhine drivers
too. Don't know how to do it for epic100.
+ p910nd-0.4 in contrib/ has -f device option now to specify other
printer ports, e.g. USB.
+ Robb Main found a bug with the #ifdef logic in loader.S. This may fix
problems with BIOS detection.
Released as Etherboot 4.7.24 (development)
+ Paolo Marini sent in some code to make it work on his bare metal (no
standard BIOS or peripherals) platform. This may be a useful starting
point for some applications. See contrib/baremetal/.
+ Eric W. Biederman contributed a Perl script in
contrib/award_plugin_roms/ to list flash BIOS plugin components.
+ Marty Connor rewrote the Tulip driver to handle many more variants.
+ For PCI ROMs loader.S can now detect if it's being called from a PnP
BIOS and choose to hook INT19H if not.
+ Pass struct *rom_info in priv_data to probe routine. This is to allow
drivers to decide, based on the ROM address, which one of multiple
instances of identical network adaptors to activate. Started on 3c509
code to use this but need to understand 3c509 contention resolution
mechanism first.
+ Link src/lzhuf.c to contrib/compressor/lzhuf.c so that we don't need
to refer to contrib/compressor/lzhuf.c anymore in Makefile.
Released as Etherboot 4.7.25 (development)
+ Minor documentation edits, merged in NIC entries for newly supported
Tulip variants from Marty Connor.
+ One last minute change, Robb Main suggested calling cs89x0_reset()
from cs89x0_disable() to shutdown the hardware cleanly.
+ Updated tftp-hpa to 0.17.
+ Slight mod to lzhuf.c to make compression statistics report shorter.
Released as Etherboot 5.0.0 (production)
+ Donald Christensen found a small bug in osloader.c. Not all context
was cleared on tftp restart which caused restarted tftp loads to fail.
+ Correct a small error in setting %sp when not running at 0x9xxxx.
Now relocation to 0x84000 works.
+ Marty Connor added a generic Tulip entry and renamed the Macronix
entries because PHP doesn't like strings starting with digits (for
rom-o-matic.net).
+ In loader.S, move code to save ROM segment and length to before jump
to new segment, otherwise if MOVEROM is defined, then the ROM segment is
always 0x8000. In etherboot.h, define an inline function to say if a ROM
address is ok to boot from. Allow if < 0xC0000 or matches assigned ROM
address of NIC.
+ Thomas Kessler found a bug in vendortags.sgml re option-NNN tags in
dhcpd.conf, the wrong syntax was presented. However on trying the
option-NNN syntax documented in the dhcp-options man page, it was
discovered that option option-NNN is no longer supported in the old way
in recent versions of ISC dhcpd v3; a new syntax should be used. Added
note to vendortags.sgml to warn users.
+ Incorporated changes suggested by Hannu Martikka to #define
DEFAULT_KERNELPATH in etherboot.h for rarp(), and display the TFTP
server address before filename in Loading: message.
+ Split off documentation into separate package in anticipation of
production/development series split. Moved previous LOG to top level.
Moved distribution section of index.html into separate web page so that
index.html will be less ephemeral.
Released as Etherboot 5.0.1 (production)
+ Arkadiusz Miskiewicz pointed out that --oformat should be used instead
of -oformat as old ld accepts both while new ld requires --oformat.
+ contrib/{tftp-hpa,atftp} are distributed separately from the
distribution page to make them easy to update.
+ Eric Biederman contributed many small changes in the code to improve
the behaviour in exceptions and generally improve the code structure:
1) Cleanup etherboot restarting. There is now only one place that needs
to test for EMERGENCYBOOTDISK.
2) Change pci.c as I have suggested. It is setup to scan every possible
pci bus until it finds an etherboot card.
3) Change osloader.c so that if an image that can return, but isn't
supposed to it restarts etherboot with -2 instead of the returned value.
4) Rewrites the delay logic so that we compute how long we should sleep,
and then sleep the whole time in await_reply so in a congested networks
we don't miss slow packets.
5) divides load into load & load_configuration. This removes the need
for the weird bootp_completed variable. And makes it a little more
explicit what we are doing.
6) add an interruptible_sleep function so that we can sleep and still
process keystrokes.
7) rewrites the restart logic:
- renames jmp_bootmenu to restart_etherboot.
- removes bootmenu (The function isn't)
- It explicitly does an eth_reset & eth_probe pair to reinitialize
the interface. This should help if someone has plugged the
interface into a different switch since booting started.
- moves ASK_BOOT and TRY_FLOPPY_FIRST into their own functions.
- On every restart calls ask_boot and try_floppy_first. Allowing you
to change your mind on how you want to boot after network booting
starts.
8) In cleanup calls both eth_disable (to disable the interface) &
eth_reset to make certain the interface can be initialized from linux.
(If nothing else this should cause more hidden bugs to show up).
9) Restart etherboot when downloading a bootfile fails, instead of just
looping trying to get that file. Allowing typos in dhcpd.conf to be
corrected without having to reboot the client machine running etherboot.
Released as Etherboot 5.1.0 (development)
+ All the changes from 5.1.0 carried over except calling eth_reset()
from cleanup().
+ Marty Connor, funded by Sicom System (http://www.sicompos.com/), wrote
a driver for NICs based on the National Semiconductor DP83815, e.g.
Netgear FA311/FA312. Also independently created by Jason McMullan just
at the time Marty released his driver. Thanks for the effort Jason;
great minds think alike. Both are based on Donald Becker's Linux driver,
of course.
+ Doug Ambrisko contributed a patch to take environment bindings for
FreeBSD kernels from a BOOTP/DHCP option or config variable.
+ Dax Kelson contributed an example of an ISC DHCP config file that uses
Vendor Class Identifier to tailor the response to Etherboot clients.
Also discovered that the Etherboot VCI should also be sent in the
DHCPREQUEST message, in addition to the DHCPDISCOVER message. Note that
the DHCP server must be set to non authorititative if you have an
authoritative server running already or it will interfere with that
one's operation.
+ Peter Lister and Vasil Vasilev contributed changes to generate .pxe
images bootable via PXE.
+ Eric Biederman added code to 3c90x.c to enable the NIC: set up
busmastering and set the latency timer in case the NIC is not already
set correctly, and fixed a couple of related bugs in eepro100.c.
Verified that the 3c90x driver works for the 3c980.
+ Moved strncmp from osdep.h to linux-asm-string.h. Use the general
version using string ops, not the deprecated 486 version (what was I
thinking). Also added strlen, needed for FreeBSD patch above.
+ Thanks to gcc 3.0, found and corrected a couple of C constructs of
undefined semantics in rtl8139.c and lance.c of the form: i = ++i &
MASK;
+ In Config/CFLAGS32: changed -m386 to prefered form, -mcpu=i386,
changed -O2 to -Os, and added -ffreestanding. These changes allow
warning-free compilation under gcc 3.0. Only mimimal testing has been
done with gcc 3.0 compiled binaries, we hope there are no problems but
don't throw away your gcc 2.9.5 yet.
+ Added an .org 0 to loader.S just before _start. May or may not fix
alleged assembly problem with gas 2.11.
+ Cosmetic change: in boot1a.s replaced "loaded" with "done\r\n" so that
Etherboot messages start at beginning of line.
+ More improvements to contrib/mkffwnb.
Released as Etherboot 5.0.2 (production)
+ Added missing rules in genrules.pl for .pxe and .lzpxe images.
+ Peter Lister unified pxeloader.S into loader.S. pxeloader.S not
required now. Also fixed .lzpxe.
+ Added missing int i; declaration in try_floppy_first().
+ Load %edx with dev just before calling xstart in floppy.c:bootdisk()
so that %dl will have device number, just like entry from BIOS.
+ Merged in Eric Biederman's patches to build .ebi images that run under
LinuxBIOS. To make an image, edit Config to enable the EBI options (and
disable TAGGED_IMAGE), then make bin32/driver.ebi, where driver is the
name of a supported PCI NIC.
Released as Etherboot 5.1.1 (development)
+ The rotating bar progress display has been replaced by a sequence of
dots, one for each transmitted packet. This is kinder to dumb displays,
e.g. serial terminals, and gives a better feel for how the loading is
going. If you want the rotating bar, use -DBAR_PROGRESS.
+ In loader.S change .fill 0x18-(.-_start) to .org 0x18. Might help
people having errors assembling it.
+ Do Jong Gwan found a 3Com 980 with PCI ID 0x9805. Added to config.c
and NIC. Added for good measure 0x7646 which is listed as 3CSOHO100-TX
in Linux kernel 3c59x.c.
+ Add a rule to the Makefile to check for gcc 2.96, which is buggy, and
tell the user to use kgcc instead if found.
+ Till Straumann added long-needed code to warn when fragmented packets
seen (encountered on a wireless link) and to do UDP packet checksumming.
+ A trio of patches from Klaus Espenlaub, to fix a lance ring pointer
error in lance.c, to fix a format error in the multiboot call in
osloader.c and a patch to enable powersaving while waiting (good for
compute clusters and VMware), this one requiring the new option
-DPOWERSAVE in compiles.
+ While we are adding compile options, -DFLOPPY has been renamed to
-DCAN_BOOT_DISK as FLOPPY has been a misnomer ever since the ability to
boot /dev/hdX and /dev/sdX was added.
+ Spurred by correspondence from Till Straumann and Klaus Espenlaub,
hacked printf to not require a buffer. Now printf output can be
arbitrarily long as it no longer needs a buffer to assemble the
characters before sending to putchar; it outputs on the spot for
non-format chars and %s items, and at the end of the item for non-%s
items.
+ DRIVER AND EXTENSION WRITERS NOTE! (s)printf formats have been changed
to be a subset of those in glibc to reduce confusion. The changes are %x
-> %hX, %b -> %hhX, and %I -> %@. Lower case x formats are also
available now. The only variances from glibc are %@ for dotted quad IP
addresses (formerly %I; %I is now used), %! for 6 byte Ethernet
addresses, and that printf returns void. Thanks to Klaus Espenlaub for
assistance on this, after adding the %! format, he cleaned up all of the
Ethernet address display code in the drivers.
+ More cleanup patches from Klaus Espenlaub (he's better than lint;
people who have used Bell Labs Unix will know what lint is). Changes
noted here for posterity.
3c509.c: consistent non-use of # modifier for debugging output
3c595.c: consistent non-use of # modifier for debugging output
3c90x.c: use optimal %x variant, PCI bus/function numbers are always small
Config: Replace a TAB by two spaces inside the descriptions
eepro100.c: 6->ETH_ALEN, PCI bus/function numbers are always small
floppy.c: optimal %x variant
genrules.pl: consistent use of TAB characters
i82586.c: the ENET address printing patch for the EXOS205 got lost somehow....
main.c: cleanup of the UDP_CHECKSUM comment some editor messed up, make the
assembly fragment use the normal formatting, fix the register assignment
specification for the %bx register to use the "b" constraint instead of
"bx" - the x makes no sense...
natsemi.c: %X case fix...
ns8390.c: optimal %x variant
pci.c: fix bad Linux port (most messages truncated the hex values)
sis900.c: a value read with inl() should probably(!) be printed with %X
start32.S: move around the #endifs a little
timer.c: fix space/tab characters
via-rhine.c: all values "printed" inside the comments are 32 bit integers
wd89c840.c: PCI bus/function numbers are always small
Released as Etherboot 5.0.3 (production)
+ New version of contrib/Diskless-From-NT/furtmayer.html. I mangled the
previous version by forgetting to extract with metamail so it was still
quotable-printable encoded.
+ Renamed do_printf to vsprintf because that's the standard function it
has the same signature as.
+ More patches from Klaus Espenlaub. In his own words:
The patch to add UDP checksums for transmitted packets is attached.
Just don't be surprised if some packet sniffer tells you that the
checksum for the NFS_LOOKUP packets are wrong and that the filename is
truncated. It's a bug in the sniffer, not in Etherboot.
Oh, and the small change in udpchksum() almost makes up for the
increased code size.
I also rewrote the NFS code to use pointers instead of array accesses.
This reduced the code size by 124 bytes. Patch attached.
The last patch in this mail fixes misc things: a typo in misc.c
(DOT_PROGRESS instead of BAR_PROGRESS), and twiddle() is only called if
the packet type is IP. This makes the output nicer - the dots are also
printed in some non-approriate places for ARP reply packets. The
important packets are IP anyway.
+ The option BOOTP_DATA_AT_0x93C00 is deprecated, in preparation for
expanding the parameter area and the first32.c area.
+ Marty Connor found a typo in index.html, should be: Etherboot can work
with..., not Ethernet can work with... Ooops.
+ Eric Biederman tried a patch of Preston Wilson's and discovered that
DI should be prefixed by ES in the test for a PnP BIOS in loader.S to be
sure. Furthermore some BIOSes are not fully compliant and we need an
#ifndef PNP_BUT_NOT_BBS_COMPLIANT to work around that.
+ Oops, there's no entry in config.c for the DFE530TX+ even though
there's one in NIC.
Released as Etherboot 5.0.4 (production)
+ Fixed a struct alignment (8-byte constraint) problem in lance.c caused
by the introduction of the rx_idx field by moving rx_idx to the end of
the struct. Found by Rizsanyi Zsolt. Klaus Espenlaub also suggested
increasing all the Rx buffers by 4 bytes because of the checksum stored
at the end.
+ Fred Gray contributed changes in tulip.c to check for a duplex
connection and to modify the controller register if so. Marty fixed an
unassigned to "negotiated" variable.
+ Mark G of Inprimis Technologies contributed another FA311 (National
Semiconductor DP83815) driver, also based on the Donald Becker Linux
driver.
+ Armin Schindler contributed a patch to allow booting LynxOS KDI
images.
+ Moved code to set PCI busmastering and reasonable latency to a routine
in pci.c and added calls to this routine from all PCI drivers.
+ New files for contrib/mkffwnb for version 1.9.11 and 1.9.16.
+ Removed BOOTP_DATA_AT_0x93Cxx option.
+ Convert epic100 driver to use hardware timer for transmit timeout and
remove polling loop from receive routine.
+ Steve Tilden pointed out that BOOT_INT18H is a LCONFIG option, not a
CFLAGS32 option. Put note under option documentation and also added a
commented-out example in Config. Steve also contributed a patch<63> in
contrib/auto-default, which autoboots from the next device if a disk is
detected.
+ PNP_BUT_NOT_BBS_COMPLIANT option renamed to BBS_BUT_NOT_PNP_COMPLIANT.
+ Merged in Vasil Vasilev's changes to loader.S to release memory taken
by PXE properly.
+ E820 memory detection routines added by Eric Biederman. May increase
size of bss segment and push large drivers, e.g. Tulip, nearer to limit,
please report.
+ Default to -DCONGESTED in Config, may help on busy networks.
+ Add Holtek HT80232 to list of NE2000 PCI clones.
+ Remove prohibition on loading < 0x10000 in ELF images since by default
drivers don't use memory < 0x10000 any more, with 48kB to run in.
+ Put define of ETH_MAX_MTU in etherboot.h inside #ifndef so that it can
be overriden from Makefile.
+ Gustavo Junior Alves added .cvsignore files for src/bin and src/bin32.
+ Short note on how to make tomsrtbt netbootable in contrib/tomsrtbt.
This release is dedicated to the memory of my mother (July 1917 -
November 2001) [Ken Yap].
Released as Etherboot 5.0.5 (production)
+ Changes to enable fa311too driver which were overlooked in 5.0.5.
+ Chien-Yu Chen sent in patches to support the SiS630ET. Independently,
Doug Ambrisko made the same changes. Marty Connor tidied the patches.
+ In misc.c, when enabling/disabling Gate A20, call int 0x15 with
ax=0x240x to do handling first, and if that is not supported, fall back
to using the keyboard controller. Hopefully this will solve Gate A20
problems for recent BIOSes.
+ Add missing entry to config.c for the Macronix 98713 (device ID
0x512). But latest report is that it doesn't transmit. Anybody wanna
debug?
+ Omit test for pointer to $PnP string for ISA NIC images, it may
trigger false recognition of a PnP ROM. Just use legacy mode.
+ Merged in Christopher Li's Intel E1000 gigabit Ethernet driver.
+ RISKO Gergely found that the ADMTek Comet 983 works with the tulip
driver if you provide the right PCI IDs.
+ Rohit Jalan contributed patches to support FreeBSD booting via PXE.
(genrules.pl needed hacking to make it ignore the system includes in
osdep.h.) Anybody want to see if it can be made to support pxelinux?
[Glanced at it and I think general PXE support may be hard, you may need
an Etherboot specific secondary loader. - Ken]
+ Merged in Eric Biederman's patches to allow trying all PCI devices.
+ From Eric Biederman: A small patch to allow the serial port parameters
to be unchanged at activation. Major changes to start32.S to merge
LinuxBIOS support. New files for LinuxBIOS support. PCBIOS specific
functions split out into pcbios.S. Massive clean up of PCI subsystem
logic.
+ Jean-Jacques Michel sent in a fix for via-rhine.c to make sure the
transmit is finished before returning from the _transmit routine.
Also found a bug in gcc 3.0.3 that affected rtl8139.c. Moving the
assignment to nstype in _transmit two lines up avoids it.
+ Based on the experience of Yedidyah Bar-David, in eepro100.c,
increased udelay around line 533 after getting MAC address to
udelay(10000).
+ Added PCI IDs for RTL8129, which can use the rtl8139 driver.
+ Added PCI IDs for 3Com905 with device ID 0x9058. Confirmed working by
Fabio Papa.
+ Added PCI IDs for D-Link 528, which is a PCI NE2000 clone.
+ Philip R. Auld found a block number rollover bug due to promotion to
signed in main.c.
+ Luigi Rizzo sent in a patch to nfs.c to implement an adaptive timeout.
+ New config files for floppyfw-1.9.19 in contrib/mkffwnb/.
+ Glenn McKechnie contributed a Perl script for making a netbootable
image from the Dachstein LRP firewall distribution floppy. It's in
contrib/mklrpnb/
+ At the request of Greg Beeley, who got irate mail from kernel NIC
developers, put in a warning in the Makefile about the 3c90x XCVR
options which may affect later operation with the Linux driver. For you
tinkerers out there, if you don't know what you're doing, please read
3c90x.txt over and over again until you understand what those options
do. If you don't understand, please ask on the Etherboot mailing list.
And don't complain to the kernel developers, it's nothing to do with
them. If you must change the XCVR options on a board, please document it
prominently on the board so that those who come after you won't
encounter strange behaviour and complain to the kernel developers.
Greg also supplied a patch to 3c90x.c to print a warning message.
Released as Etherboot 5.0.6 (production)
+ Andrew Bettison sent in a patch and the explanation: Here's a patch
for some changes I made to Etherboot-5.0.6 because it didn't work with a
SMC EtherEZ in an old PCI/ISA bybrid bus system. The ISA shared memory
isn't accessible on many such systems, so the only way to do I/O to the
card is in Programmed I/O mode. I studied the Linux 2.2.19 driver
(drivers/net/smc-ultra.c) and hacked what I figured was equivalent code
into src/ns8390.c, and it eventually worked. All my new code is enabled
with -DWD-790_PIO.
+ Small error in the ADMTEK Comet 983 IDs fixed.
+ Michael Rendell sent in patches for 3c90x.c to get the MAC address
from location 10 of the EEPROM onwards, like the Linux driver does. Some
905s have the MAC address at both 0 and 10 which is why it worked for
some boards.
+ Michael Brown sent in drivers for 3 wireless NICs based in the prism2
chipset, and a small patch to rtl8139.c to abort detection on no link.
+ Rewrote makerom.c in Perl to give makerom.pl.
+ Rewrite genrules.pl to parse a new NIC format.
+ Timothy Legge contributed a 3c515 driver. Requires a ISA PnP BIOS.
+ Modified call to int15h/e801 in pcbios.S to check for return values in
CX, DX in case BIOS doesn't return them in AX, BX.
+ Richard Chan sent in PCI IDs for another Intel EEPRO100 product.
Omigawd will they ever run out of EEPRO100 model numbers. :-)
+ Changed location of setup header from 0x97e000 to 0x93e000 in
mkQNXnbi.c for recent Etherboot versions.
+ Renamed membase to addr1 to reflect its lack of predefined meaning in
PCI config space. Should do similar to ioaddr, but too much work.
+ Samuel Clememts found another Intel EEPRO100 device ID, 0x1039.
+ Updated instructions in contrib/tomsrtbt for latest 2.0.103 release.
+ Folded in changes by Michael Brown to send PCI and ISA IDs to the
server and to encapsulate Etherboot specific options. Changed scheme to
send fixed binary structure instead of variable length string.
+ Bug in sis900.c, wrongly classifies revisions 0x81 and 0x82 because
first test catches too many revisions. Changed to match the Linux
driver.
+ Fotis Andritsopoulos found a small bug in cs89x0.h, TX_AFTER_ALL
should be 0x0C0.
+ Great idea by Eric Biederman. Ignore DHCP offers with zero server
IP, or null filename unless DEFAULT_BOOTFILE is defined. This will
ignore most Windows DHCP servers.
+ Patrik Weiskircher sent in a patch for rtl8139.c to bring it up to
date with the Linux driver.

and PXE images, those formats were broken. He also migrated the PCI IDs
into the driver files. Those formats should work again.
+ Reworked genrules.pl. Family declarations now in here document inside
genrules.pl. NIC is now an output file, for use by rom-o-matic.
Released as Etherboot 5.1.7 (development)

that applies to Etherboot driver too.
+ Add use bytes; pragma to Perl scripts to avoid problems with UTF-8
handling of input data.
+ Replace boot1a.s with floppyload.S which has no problems loading large
binaries. Lose the ability to boot from disk partition. Use LILO or
something similar.
+ Morten Kristiansen sent in a patch to handle another variant of the
SiS 900.
+ Fix for eepro100 timing problem by Georg Baum.
+ Add use bytes; to Eric's Perl scripts too.

Released as Etherboot 5.1.9 (5.2 release candidate 1)
+ 82562EZ ID provided by Samuel Clements.
+ Rename Local option as Quit, because that's what it really is.
+ Should prepend start16.bin to .com images, they didn't work and nobody
noticed.
+ PM stack was getting clobbered by zeroing of BSS, move to own segment
in etherboot.lds. Move %ss out of the way of Etherboot in comprefix.S.
Now Q works from .zrom and sort of from .com (DOS is odd after return).
+ Make ASK_PROMPT reflect the device options available.
+ Removed many outdated comments and updated others.
Released as Etherboot 5.1.10 (5.2 release candidate 2)
+ Make floppyload.S and liloprefix.S call instead of jmp to the image so
that the return calls int 0x19, which is somewhat better than
hyperspace.
+ Put http://etherboot.org in prompt and ID string.
Released as Etherboot 5.2.0 (production)
+ Print F? if no filename in DHCP offer.
+ Make lance.c throw a compile error if -DRELOCATE is used.
+ pcnet32 driver ported by Timothy Legge.
+ Reinstate boot1a.s in arch/i386/prefix. The binary may have some uses;
it boots with vmware although the image fails later in the emulation.
Released as Etherboot 5.2.1 (production)
CVSed as Etherboot 5.3 (development)
+ Break out etherboot.h into multiple files along protocol lines.
+ Georg Baum's conversion of a more recent version of the Linux e1000
driver.

+ Timothy Legge rewrite proto_tftm.c, got multicast working with atftp
and enabled multicast for the Tulip.
Released as Etherboot 5.3.1 (development)
+ G<>nter Knauf sent in a new version of romid that handles the new
and old IDENT format.
+ Cai Qiang fixed the WINCE loader. It needs to handle > 512 byte packets
and also the buffer has to be static. Also submitted a driver for VGA
which can be activated by CONSOLE_DIRECT_VGA.
+ Improved tg3 driver by Eric Biederman. New define in etherboot.h:
VALID_LINK_TIMEOUT.
+ Timothy Legge and I fixed up various ISA drivers to be less noisy
when probing, from information provided by Paolo Salvan, so that the
super etherboot image is more useful.
+ Proof of concept of a TFTP to HTTP proxy in contrib/t2hproxy/.
Released as Etherboot 5.3.2 (development)
+ Multicast support for the ns8390 (NE, WD, etc) added by Timothy Legge.

+ UNDI driver by Michael Brown.
Released as Etherboot 5.3.3 (development)
+ More UNDI improvements by Michael Brown.

+ Start of PCMCIA subsystem by Anselm Martin Hoffmeister.
+ Port to Hyperstone architecture (big-endian) by Yannis Mitsos and
George Thanos at NTUA, Greece.

when 5.2 released. Also implemented multicasting. Also tentatively
fixed the tg3 driver.
+ Use Perl script to make .z?lilo images.
+ Added an .iso Makefile rule. This requires newer BIOSes as it
uses no floppy emulation mode.
+ Guard Kuo sent in a patch for the via-rhine driver not being
reset properly, Timothy Legge improved it based in the Linux driver.
Released as Etherboot 5.3.4 (development)
+ David D. Smith, with help from Georg Baum, sent in a patch for the
eepro100 driver which might help unjam the NIC when the receiver has
suspended reception.
+ Timothy Legge and Eric Biederman fixed a bug in the tg3 driver which
caused some models to not receive DHCP replies.
Released as Etherboot 5.3.5 (development)
+ Timothy Legge ported the Linux Realtek 8169 driver.
+ Michael Brown removed irritating A20 status change messages.
+ Sis900, w89c840 and tg3 drivers fixed by Timothy Legge. R8169 driver
needs family entry in genrules.pl.

newer devices that support port I/O. Enabled port io for the reset.
Without the patch the e1000 could not reliably boot Linux on some
cards. Thanks to James Pearson, Georg Baum and Marty Connor for
help resolving this issue.
+ Michael Brown added lots of PXE code to complete implementation. He
also did a warnings purge of the core.

Released as Etherboot 5.3.8 (development)
+ Update to lance.c chip_table from Helge Wagner
+ Fixes to attributes to prevent gcc from optimising away seemingly
unused functions and variables that are actually referenced from asm
or in the linking stage. (Ken Yap)
+ Removed non-relocation support, relocation is now always active.
Removed lance.c driver as this will not work with relocation. 32-bit
Lance NIC users should use pcnet32. (Ken Yap)
+ Migrated SAFEBOOT to a patch set. This proof-of-concept code is
incomplete and needs more work before becoming mainstream. (Ken Yap)
Released as Etherboot 5.3.9 (development)
+ Patch from Tim Fletcher for another eepro100 model.
+ Patch from Jeremy Jackson to make DNS query recursive and fix sign and
casting issues in dns_resover.c.

(ICH5/ICH5R)"
+ Small patch to support 3Com tulip version from Jacek Kalinski
+ Yinghai Lu contributed a large patch to add filo, bText and usb
support:
btext console: In LinuxBIOS, for the VGA, we only can
enable display chipframe buffer and write char to framebuffer
to get output in CRT.
FILO: originally it is standalone boot program and
author is TakeshiSone.
Boot from SATA disk.
Boot from USB disk (OHCI and UHCI). USB boot is from Steven
James 's baremetal in LinuxBIOS, moved to FILO and added the
OHCI support to it
+ armnommu arch support by Tobias Lorenz.
+ Driver updates/cleanup: rtl8139, sis900, tlan
+ Updates to via-rhine based on input from Guard Kuo from Via Networking
Technologies, Inc

images may be broken.
+ Start of a .exe prefix which should allow payloads > 64kB.
Released as Etherboot 5.3.11 aka 5.4RC2 (development)
+ Left out in last release's LOG: accepted patch from Jan Kiszka
fixing default TFTP blocksize.

+ New mtd80x.c driver contributed by Erdem Guven
+ New dmfe.c driver for Davicom based cards contributed by Timothy Legge
+ Added new definitions of site DHCP options in preparation for 5.4.
+ Removed etherboot(-pci)?.* rule because there are too many drivers and
the image will no longer fit in memory. I don't want to choose a subset
of drivers as everybody will have different preferences. So I'm going to
piss off everybody equally by deleting the rule. Use the multiple driver
rule (driver1--driver2--...) and select your own subset of drivers.
Released as Etherboot 5.3.12 aka 5.4RC3 (development)
+ Changes to Makefile.main and Config to collect FILO objects in
filolib.a. This allows FILO to be excluded from compilation and linking
with one Makefile define.
+ Reverse site DHCP option changes, should apply for official
assignment.
+ RIS filename patch which seems to work for many people.
+ Thanks to the help of Daniel Nilsson, tracked down and fixed a bug
where the tftp code did not fall back to 512 byte blocks when an OACK
was NOT received.
+ Removed dead code related to CAN_BOOT_DISK.
+ Clarified that BOOT_DISK and BOOT_FLOPPY options only work with
LinuxBIOS and are not replacements for PCBIOS functions.
+ Renamed EMERGENCYDISKBOOT to EXIT_IF_NO_OFFER.
+ Builtin menuing DHCP options are gone.
+ Paolo Salvan submitted changes to arch/i386/Makefile to make .com
images compressed.
+ Eric Biedermann made .*elf images work again and cleaned up the build
procedure in the process. The hardwired virtual RELOCADDR is no more,
the virtual base is 0. He also added code to display which protocols are
compiled into the image.
Released as Etherboot 5.3.13 aka 5.4RC4 (development)
+ Lots of fixes by Eric Biederman. Symbols for protected mode segment
and prefix segments separated. Multiple ASM statements combined to
ensure compiler keeps them intact. Allocate real mode stack if none in
use. Protect low memory interrupt vectors. Makefile rules for various
prefixes factored. Dynamic relocatable image support.
+ Fixes by Michael Brown. Cleanup of PXE and UNDI code.
