Well, IIRC x86emu does not only emulate x86 instructions, but also calls to 16bit BIOS. I'd like to rip the BIOS emulation code out of x86emu and use SeaBIOS for that. > If you mean using seabios to implement the option rom scan - then yes, > I think this is what Stefan suggested and Zhang Rui is working on.
