You can have both DOS and unix partitions on the same hard disk, and boot
from either; (I think this is the answer Alan was looking for). I've 
sucessfully booted DOS as partition #2 (i.e. not starting at cylinder 0) with
both SCO and Esix; I'm told it doesn't work that way with ISC, DOS must start
at cylinder 0, but I've not verified this.

I have a program which (i think!) allows you to decide what partition to boot
from when you power up. That's how I understoodthe explanation given with 
the program, never installed it. If you want mode info, e-mail me.
