	Don't know if this is universally the case. I'm running Xenix/386
on an NEC 386/20 (C/T chipset, Phoenix BIOS) which reserves 384k. Neither
Xenix nor ISC UNIX (which I also run on this box) access this memory, as
verified at boot time. Of course, if someone *does* know a way to access
this memory, please advise!
