Ok. If you prefer this solution you could, as I mentioned, try to
contact the Linux graphics driver developers. There are people from

Thanks. I think it is helpful. Please follow Kevin's suggestions to
find out more about what the ROM is trying to do.

BTW this sort of thing can happen when the code calls a function, the
stack is bad, and it returns to la-la land. That's why I'm curious
about %esp.

well how about this as a first step. We're getting exception 6. What
is that again?
Also: is 0x8e41a854 even remotely valid as a bios int?
And: 8831:eb60 -- 96E70 -- is that a sensible place for the CPU to be?
It looks to me like the stack is somewhere odd: 774a. Is that right?

Joe already mentioned it, but there is a big different in the amount
and quality of legacy BIOS interrupt services available at VGA

Hi
I keep getting "ILLEGAL EXTENDED X86 OPCODE!" from my VGA ROM while trying
run VGA ROM in coreboot.
I tried x86emu, yabel and real mode for running VGA ROM with no luck. But
the same VGA ROM is running with seabios.
I am attaching the boot logs with x86emu, real mode and with seabios.
