I was misunderstood. I didn't mean to say that NetBSD used the BIOS.
I meant to say that the warm start (Ctrl-Alt-Delete) and the cold start
(location 0) vectors that are used at powerup and under DOS basically
jump into BIOS.
My basic point was regardless of how hacked a given machine is for
compatibility, the BIOS routines (in theory) always get it right on a
given machine. So the question was, for a reliable reboot, why not just
take the machine back into real mode and let the BIOS work? The
BIOS data area isn't that big to preserve.
