Yes. Everything runs natively. SeaBIOS provides the BIOS stuff needed
by option ROMs.

It is great progress!

However, x86emu only really emulates real mode AFAIK, and not all
option ROMs stick to that. They could assume that protected mode is
available and enable it during their run. Have you looked into
handling this also in biosemu? Have you seen this behavior in any
option ROMs? Have you already done extensive testing?
