re: the video bios, do we need to write one really? I mean, why not
just for real-mode stuff implement a simple bios-vesa2 interface
which somehow communicates with plex86 instead of the emulated
video hardware? Would be a dedicated guest-driver but for anything
running in real-mode. Not too many functions to emulate i believe.
Any thoughts?
