Marty Connor 4e177aee17 Change #warning to FIXME for depca 
This ancient ISA driver should probably be removed.
It is hard to get a card to test it with, and there
are comments to the effect that it cannot work with
relocation.  I would be quite interested to get a
bug report by someone who actually has this card.

Marty Connor 767a3cef77 Changed #warning to FIXME for nvo hack warning. 2007-07-22 20:52:32 -04:00
Marty Connor 63c9131eeb Add NIC to targets that are always made. 
Even though it is only currently used for rom-o-matic.net code,
it is good to make sure it gets built, and that the parsing code
is working.

Michael Brown 07e11f8af9 Minor debug improvement 2007-07-19 17:01:21 +01:00
Michael Brown 2cfe0dee1f Don't trash the %ecx value returned by relocate(). This was causing 
us to round down the size for the relocation copy to the nearest 64kB
(+0x10 bytes); this just happened to work on most machines because the
last 64kB of the image is all-zeroes anyway (it's the .bss).
 2007-07-19 16:07:31 +01:00
Michael Brown a8111e8ab7 Remove INT 13,4b handler; it represents an incomplete feature (CD-ROM 
emulation support) for an unknown purpose, and breaks grub.
 2007-07-19 11:16:05 +01:00
Michael Brown 0d9d2ccbae Completed definition of struct int13_cdrom_specification, and moved to 
int13.h.
 2007-07-19 11:15:01 +01:00
Michael Brown 013d381e3c Real-mode code might set the direction flag, which would cause carnage. 2007-07-17 13:46:37 +01:00
Michael Brown c94cdf2b7d Move .zinfo to libprefix.S; it doesn't belong with the decompression code. 2007-07-17 12:52:54 +01:00
Michael Brown cb237819ca Produce no output unless -v is specified or an error occurs. 2007-07-17 01:59:48 +01:00

Michael Brown 60ce8e884d Added missing extern 2007-07-17 01:16:24 +01:00
Michael Brown c3290aae54 Use objdump -t for symcheck; it allows us to take the symbol section 
into account (and so remove the false positives due to .tbl.* symbols).
 2007-07-17 01:15:39 +01:00
Michael Brown 38dbe14bbe Kill off redundant references to the .zprefixes. 2007-07-16 17:26:07 +01:00
Michael Brown 84551d485e Update all prefixes currently referring to _load_size to include a 
compressor fixup section.
 2007-07-16 17:17:26 +01:00
Michael Brown 0929142a15 Rename _rom_size to _load_size_sect, since hdprefix.S also uses it. 2007-07-16 17:03:19 +01:00
Michael Brown 048bbeeebc Compressed ROM images now work. 2007-07-16 16:58:38 +01:00
Michael Brown 37fa9a8706 Split the objcopy stage out of final image preparation to a separate 
bin/%.bin target.
 2007-07-16 13:41:27 +01:00
Michael Brown 6d2e4e719c Move uninitialised .data16 variables to .bss16; saves around 2000 
bytes of useless zeroes in the final image.
 2007-07-16 13:22:12 +01:00
Michael Brown 389204713f Kill off some long-redundant CFLAGS 2007-07-16 13:15:12 +01:00
Michael Brown 833d6cc8ec Add __bss16() macro, and allow use of .bss16 section by removing 
link-time check for section overlaps.  (In order to avoid wasting
space in the executable image, .bss16 will overlap with the following
section, which is .text).
 2007-07-16 13:10:49 +01:00
Michael Brown c482fc90fb Revert "no need for depending on build library ("blib")" 
This reverts commit 9dc2515d7e.

I want "make" to actually build something.
 2007-07-16 13:06:58 +01:00
Michael Brown a8780a4fe4 Added nrv2b binary to ignore list 2007-07-15 13:31:31 +01:00
Michael Brown ab859a5355 Use a single _payload_offset linker-defined variable to locate the 
start of the non-prefix blocks in the loaded image, and rely on the
image ordering.  This should make introducing compression much easier.

"rep movsb".

Michael Brown 3feac9465e "not" doesn't affect flags, "xor $-1" does. 2007-07-15 01:25:13 +01:00
Michael Brown 7e3a8f5e10 Remove more obsolete files 2007-07-14 23:16:01 +01:00
Michael Brown 26473105cd On advice of hpa: be more patient with the KBC and SCPA methods; retry 
in a long loop before giving up on them.  Record method which worked
and default to that method on next attempt.

Michael Brown adf192f566 Shrink cpu.c and render it useful for our purposes. 2007-07-14 19:12:13 +01:00
Michael Brown 25fd42ca87 Reduced etherboot.h dependencies to avoid unnecessary rebuilds. 
etherboot.h is only now used by drivers that have not been updated to
the new API.
 2007-07-14 15:52:23 +01:00
Michael Brown e330db3c74 Dead code removal. 
Kill off use of etherboot.h outside drivers/net.
 2007-07-14 15:42:26 +01:00
Michael Brown 95c07736cb Be more aggressive in attempts to enable A20, now that we have the 
optimisation of only trying to do so when necessary.
 2007-07-14 14:21:18 +01:00
Michael Brown 8624fdc445 Kill off the enforced RX quota; it only seems to hurt on real hardware. 2007-07-14 00:30:11 +01:00
Michael Brown 57b5e227ff Use fast in-situ test for gate A20 being set, to cut down on the 
number of (potentially very slow) gateA20_set operations.

Die with a fatal error if we are unable to set gate A20; if this fails
then we are bound to experience memory corruption at a later stage,
and I'd prefer to pick it up early.

Michael Brown d5735c631c Avoid reusing auto-allocated ports after connection close. 2007-07-13 11:25:00 +01:00
Michael Brown 2ac7694c3e Improve error reporting for strange length combinations reported by 
the UNDI stack.

Ignore obviously invalid length combinations (as returned by
e.g. VMWare's PXE stack).

Limit to one packet per poll to avoid memory exhaustion.
 2007-07-10 20:59:21 +01:00
Michael Brown efd322091d Set up %ds *before* testing a value in our data segment (d'oh!). 
Always send EOI; do not chain to BIOS's default interrupt handler.
They are just too unpredictable; at least VMware's seems to kill the
machine if you go anywhere near it.

Disable interrupts after return from PXENV_UNDI_ISR, just in case some
dumb PXE stack enables them.
