Well, not really... Ezbios gives you access to hard drive space that your
Bios doesn't let your OS "see."  ASPI is just a common interface for the
hardware.  It's like having a set of commands, and no matter what Cd writer
you use, it uses the same set of commands.  That makes it portable between
systems.  Ezbios is a hack to get around windows' inefficiencies. :)

Hah, I had to look that one up. :)  Segmented addressing seems to be a memory
thing, where you've got an address, and an offset from that address.  What
the hell all that means is beyond me. :)

Sure, could be.  Never thought about how ezbios worked...
