d5e39286f7 We probably shouldn't leave interrupts disabled when starting an OS. 2007-07-25 02:02:24 +01:00

6d2e4e719c Move uninitialised .data16 variables to .bss16; saves around 2000 
bytes of useless zeroes in the final image.

89349d7fad Separated out initialisation functions from startup/shutdown functions. 2007-07-03 23:09:56 +01:00

071356d976 Ensure that pxe_netdev is set before starting up PXE NBP. 2007-07-03 00:02:26 +01:00
Michael Brown
e42eba4af4 Use a common base-memory packet buffer for DHCP construction (as used 
by PXE and NBI) and UNDI packets (as used by undinet and UNDI).

5f17089b14 pxe_netdev now holds a reference to the network device. 
Use generic fields in struct device_description rather than assuming
that the struct device * is contained within a pci_device or
isapnp_device; this assumption is broken when using the undionly
driver.

Add PXENV_UNDI_SET_STATION_ADDRESS.

e1646b4080 Place the actual version string in .data16, rather than just the 
pointer to it.

8130443f9f Separate out pxe_start_nbp() from pxe_image.c into pxe_call.c 
Implement PXENV_RESTART_TFTP.

d71b116f54 Fix stack on return from PXE NBP so that we can return properly. 2007-06-28 23:37:49 +01:00

0d9b3e2dd2 Add 32-bit support. 
Generate DHCP data block for images.

Michael Brown
5578d3b2de Support 32-bit (linear) NBI images. We don't yet provide a bootp data 
block, so first32.c dies immediately.

2cf1e33df1 Split bootsector execution code out into bootsector.c. 
Added basic El Torito ISO image boot capability

6a765fdc15 Use base "0" in strtoul for consistency with "mem=" 2007-01-24 22:54:08 +00:00
Michael Brown
99cb46943f "vga=" is specified in decimal, not hex. 2007-01-22 23:56:24 +00:00
Michael Brown
ebb00e032c Misread the definition of the type_of_loader field; it should include a 
version.

a5f6408d8e We can now load an initrd as well as a kernel 2007-01-14 16:09:01 +00:00
Michael Brown
b9f99858ab Make the getmemsize() prototype available in memsizes.h, for code that 
doesn't want to go to the hassle of processing a full memory map.
 2007-01-14 15:32:25 +00:00

10c9b03cdb Actually, the initrd image should be architecture-independent. 2007-01-14 15:07:11 +00:00
Michael Brown
f92e04dea4 Add dummy "initrd" image format, just so that images can be marked as 
initrds.
 2007-01-14 15:03:39 +00:00
Michael Brown
8a490146bf Copy command line at execution time rather than load time. 
Parse command line for "vga=" and "mem=" parameters

97a3037f76 Can start a Linux kernel directly (albeit with no initrd support) 2007-01-14 12:34:35 +00:00
Michael Brown
784e10635a Can almost start a kernel now. It dies with "No setup signature found" 2007-01-14 06:36:20 +00:00

3bdbfe1f00 Mostly updated. Won't work yet. 2007-01-14 03:49:07 +00:00

7bc03d37a2 Select a PXE network device before starting PXE NBP. 
Move pxe_boot() code to pxe_image.c
 2007-01-14 02:20:10 +00:00
Michael Brown
55e6d7b70c Use debug autocolourisation. 
Shut down before jumping to the multiboot image.
 2007-01-14 00:57:43 +00:00
Michael Brown
f11900a9c6 I prefer IMAGE_XXX to XXX_IMAGE. 
Add IMAGE_PXE to use the new image format framework.  "kernel pxelinux.0"
now works.

bcd6ca3291 Place multiboot tables in base memory; at least some OSes won't see it 
if we don't.
 2007-01-12 16:25:05 +00:00
Michael Brown
0f29e0e46e Ensure multiboot modules are in ascending order of memory start 
address, to work around OS bugs.

53e948bba8 Fix the memory map. 2007-01-12 11:38:04 +00:00

6fdc6c81a6 Force probing of multiboot before ELF. 2007-01-12 08:10:35 +00:00

9debfed07a Place command-line inline, to save on memory allocation hassles. 2007-01-12 05:26:19 +00:00
Michael Brown
1d313234b3 Rename copy_user() to memcpy_user(). Add memmove_user() and 
userptr_add().

e4c6418ac0 We may be required to page-align modules, so let's make sure we catch 
it if we don't.
 2007-01-12 00:09:16 +00:00

f59ad50504 Provide registration mechanism for loaded images, so that we can e.g. 
refer to them by name from the command line, or build them into a
multiboot module list.

Use setting image->type to disambiguate between "not my image" and "bad
image"; this avoids relying on specific values of the error code.

dc51af59a4 Capable of starting a multiboot kernel (albeit without the multiboot 
information table yet).

3634e705b7 Remove osloader.c and replace with a prep_segment() that uses userptr_t 
and get_memmap() in image/segment.c
