s2892 Video card problems

[Myles Watson]

All,

The s2892 has on-board video.  When I try to put a video card in the PCI
slot I get the error:

copying VGA ROM Image from 0xfd000000 to 0xc0000, 0xd000 bytes
entering emulator
Unexpected Exception: 2 @ 10:0000bf94 - Halting
Code: 0 eflags: 00000006

edi: 0000c000 esi: 000ffff7 ebp: 0003db1c esp: 0003db1c

The only thing I turned up was an old archive post which didn't help much.

Does anyone know what the problem is?  A pointer of where to look?

Thanks,
Myles

simple answer: the vga bios is doing something that is not valid 86
mode code, and the hardware handles it and the emulator does not.

you can run that vga bios under linux and see how it goes.

Given that I can't boot the machine with the card in it, how do I get the BIOS?

Thanks,

Ron,

Thanks for the quick answer.

I just tried another add-in card from a different vendor and I get the
same error.  I'm wondering what else could cause it besides a bad vga
BIOS.  Maybe coreboot is misconfiguring the card's BAR? Something
else?

Thanks,

Myles
