If the answer is "a 386", how does it get around the "page write" >bug and others to ensure that DOS doesn't find out it's being fooled? > 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. -- ------ TSgt Dave Burgess NCOIC AL/Management Information Systems Office Brooks AFB, TX
