While I CERTAINLY do not qualify as a DOSEM expert, I recall that Andrew
Tanenbaum (of Minix fame) wrote a PC emulator for the SUN system (?) which
included a BIOS emulator.  

I agree that it is probably a little silly to have a BIOS emulator in a 
machine that presumably already HAS a BIOS, it might be a path to at least
look down.  For those of you that (like me) find it perverse to even 
suggest that we emulate something that is already there, remember that once
upon a time, the only stories about men that flew were about Icarus.  

It seems to me that he kept the emulator on one of the European machine
at the University where he worked.
