[following are related to DELL UNIX, but apply to others]

UNIX & DOS can peacefully co-exist on the same disk, in our
releases at least. Very few things can cause them to not
exist. Usually I format the system disk, make a partition
for DOS & UNIX(default boot partition), install UNIX, then go
and format c:, and install DOS.

The only real gotcha that I can see from your post(below) is
the addition of DOS 4.0 . Many UNIX implementations can not
deal with DOS *higher* than(!!) 3.3 .

Try loading 3.3 DOS, and see if that's more reliable.....
