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.
Any help?
What is the big difference while executing VGA ROM in coreboot and seabios?
Why coreboot can't run a VGA ROM which seabios can?
Thanks
Mansoor
