[Qemu-devel] Fixing ACPI for Vista -- Source code for bios.bin vs. bochs CVS?

[Qemu-devel] Fixing ACPI for Vista -- Source code for bios.bin vs. bochs CVS?

[Nakajima, Jun]

We found a way to get 32-bit Vista up on KVM by fixing bios.bin. And I
think it should be helpful to qemu as well. However, I'm not sure if the
binary file has been created simply by applying bios.diff to the latest
bochs CVS tree (actually I doubt it). Can somebody provide a recipe for
creating bios.bin from the bochs tree so that we can make a patch?

Thanks,
Jun

What makes you think this won't work? Have you tried it?

This has worked for me in the past.

Yes, I did, and that did not work.

If I try like
$ strings bios.bin |grep QEMU
Then I get different ones (I had more QEMU occurrences on the bochs
side). So I suspected they were built from difference sources. But I'll
double-check.

Regardless of whether it works or not, it would be nice to have a file 
in qemu/pc-bios detailing the revision numbers of the sources taken from 
bochs, synced on each update.  Something like the output of

    cvs status | awk '/^File:/ { file = $2 } /^   Working revision:/ { 
printf("%-20s %s\n", file, $3) }'

While we wait patiently for the patch, would you mind putting the patched bios.bin somewhere accessible (or sending it 
to me in private email and I'll put it somewhere accessible)?

There's a bunch of geeks here that would really like to best test this... :-)

Thanks!

I added -fno-stack-protector into the line 103 of the makefile in the bios 
directory and was able to compile it.

rombios32.o: rombios32.c acpi-dsdt.hex
 $(GCC) -O2 -Wall -fno-stack-protector -c -o $@ $<

It looks like qemu works fine even with unmodified bochs's bios. However, I 
still could not boot the latest beta of Vista, no matter if I applied 
bios.diff or not. I don't have the release version of Vista.
