Well as far as on power-up I believe someone posted a small little "boot menu"
for ISC to boot either to DOS or Unix on the initial boot, but I wouldn't
recommend it, unless you really switch between the two alot. I would use the`
"fdisk" commands on both Unix and DOS to switch between the two.

As far as the VP/ix definition of the D drive in the vpix/vpix.cnf file, I
definitely wouldn't suggest doing it this way. This method only leads to
a ~single-user" capability to the DOS partition. A better way is to use
Unix to mount the partition:

	# mount -f DOS /dev/dsk/1p1 /drived

Then, when under VP/ix, modify the autoexec.bat file on the virtual C: drive
to have the line:

	dosmount d:\drived

This will redirect your VP/ix session to use D: as /drived under Unix....
