H. Peter Anvin e8b6077566 [makefile] Avoid using ?=
?= in a Makefile means that that variable can be overridden by the
environment.  This is confusing to users, especially with a generic
name like "ARCH".

Michael Brown 1dda75c9cd [pcbios] Allow for larger-than-20-byte buffers in e820mangler.S
Although the E820 API allows for a caller to provide only a 20-byte
buffer, there exists at least one combination (HP BIOS, 32-bit WinPE)
that relies on information found only in the "extended attributes"
field, which requires a 24-byte buffer.

Allow for up to a 64-byte E820 buffer, in the hope of coping with
future idiocies like this one.

Michael Brown 040f7cdf3a [pcbios] Print INT 15,E820 extended attributes, if present
The ACPI specification defines an additional 4-byte field at offset 20
for an E820 memory map entry.  This field is presumably optional,
since generally E820 gets given only a 20-byte buffer to fill.
However, the bits of this optional field are defined as:

  bit 0 : region is enabled
  bit 1 : region is non-volatile memory rather than RAM

so it seems as though callers that pass in only a 20-byte buffer may
be missing out on some rather important information.

Michael Brown 50dc9344b7 [pcbios] Save/restore %es in INT 15,e820
Our INT 15,e820 code was setting %es=%ss (as part of the "look ahead
in the memory map" logic), but failing to restore %es afterwards.
This is a serious bug, but wasn't affecting many platforms because
almost all callers seem to set %es=%ss anyway.

Michael Brown 3392cfa7df [pcbios] Fetch INT 15,e820 entry directly into our e820 cache
Some BIOSes require us to pass in not only the continuation value (in
%ebx) as returned by the previous call to INT 15,e820 but also the
unmodified buffer (at %es:%di) as returned by the previous call to INT
15,e820.  Apparently, someone thought it would be a worthwhile
optimisation to fill in only the low dword of the "length" field and
the low byte of the "type field", assuming that the buffer would
remain unaltered from the previous call.

This problem was being triggered by the "peek ahead" logic in
get_mangled_e820(), which would read the next entry into a temporary
buffer in order to be able to guarantee terminating the map with
%ebx=0 rather than CF=1.  (Terminating with CF=1 upsets some Windows
flavours, despite being documented legal behaviour.)

Work around this problem by always fetching directly into our e820
cache; that way we can guarantee that the underlying call always sees
the previous buffer contents (and the same buffer address).

Michael Brown fa880ec70a [arbel] Allocate sufficient space for firmware buffer

Michael Brown c24bc349ea [pcbios] Add facility for testing arbitrary E820 memory maps
We seem to be having issues with various E820 memory maps.  These
problems are often difficult to reproduce, requiring access to the
specific system exhibiting the problem.

Add a facility for hooking in a fake E820 map generator, using an
arbitrary map defined in a C array, solely in order to be able to test
the map-mangling code against arbitrary E820 maps.

Michael Brown 887d77c27a [pcbios] Inhibit INT 15 memory map hiding on brain-dead BIOSes
Some really moronic BIOSes bring up the PXE stack via the UNDI loader
entry point during POST, and then don't bother to unload it before
overwriting the code and data segments.  If this happens, we really
don't want to leave INT 15 hooked, because that will cause any loaded
OS to die horribly as soon as it attempts to fetch the system memory
map.

We use a heuristic to detect whether or not we are being loaded at the
top of free base memory.  If we determine that we are being loaded at
some other arbitrary location in base memory, then we assume that it's
not safe to hook INT 15.

Michael Brown 35b7658877 [settings] Add the uristring setting type
This allows settings to be expanded in a way that is safe to include
within a URI string, such as

  kernel http://10.0.0.1/boot.php?mf=${manufacturer:uristring}

where the ${manufacturer} setting may contain characters that are not
permitted (or have reserved purposes) within a URI.

Since whitespace characters will be URI-encoded (e.g. "%20" for a
space character), this also works around the problem that spaces
within an expanded setting would cause the shell to split command-line
arguments incorrectly.

Michael Brown 9d44a06188 [romprefix] If we hook INT 19, prompt before attempting boot
On non-BBS systems we hook INT 19, since there is no other way we can
guarantee gaining control of the flow of execution.  If we end up
doing this, prompt the user before attempting boot, since forcibly
capturing INT 19 is rather antisocial.

Michael Brown 4011f9d956 [phantom] Skip command PEG initialisation if PEG is already running
It is possible for the BIOS to use the UNDI API to bring up the NIC
prior to system boot.  If this happens, UNM_NIC_REG_CMDPEG_STATE will
contain the value 0xf00f (UNM_NIC_REG_CMDPEG_STATE_INITIALIZE_ACK),
and we should skip initialising the command PEG.

Michael Brown e13d793160 [phantom] Omit an initialisation step now performed by the firmware

apparently breaks some newer cards.)

Michael Brown a2f9bf70d7 [pxe] Display PXE_LOADER debug message after call to initialise()
At least one Dell system calls the UNDI loader entry point with the
BIOS console disabled.  The serial console is active only after a call

can be displayed via the serial console.

Michael Brown ca0b0f0616 [relocate] Guard against systems that report empty memory regions
If the INT 15,e820 memory map reports a region [0,0), this confuses
the "truncate to even megabytes" logic, which ends up rounding the
region 'down' to [0,fff00000).

Fix by ensuring that the region's end address is at least 1, before we
subtract 1 to obtain the "last byte in region" address.

Michael Brown 0e408658b9 [iscsi] Change default initiator name prefix to "iqn.2000-01.org.etherboot:"
The domain etherboot.org was actually registered on 2000-01-09, not
2000-09-01.  (To put it another way, it was registered on 1/9/2000 (US
date format) rather than 1/9/2000 (sensible date format); this may
illuminate the cause of the error.)

"iqn.2000-09.org.etherboot:" is still valid as per RFC3720, but may be
surprising to users, so change it to something less unexpected.

Thanks to the anonymous contributor for pointing this one out.

Michael Brown 6df82b1a9d [undi] Scan for UNDI ROMs on 512-byte boundaries rather than 2kB boundaries
Apparently some BIOSes will place option ROMs on 512-byte boundaries.
While this is against specification, it doesn't actually hurt
anything, so we may as well increase our scan granularity to 512
bytes.

correct entry point.
