First, sorry for posting the whole article again net-land, but i didn't see a
convenient editing for this one.

The answer Mark, is that this:

1.)    In order for the "dos" boot to work for the xenix "boot :" prompt, there
    MUST be a DOS partition on the FIRST hard disk, which is formatted w/
    DOS's "format /S".  The /S is MANDATORY, as it places the DOS system files
    on the disk.
2.)    So, your solution is simple (if you have a tape drive, which you should).
    a.) make a level-0 backup of your 70Mb. drive.
    b.) make a bootable-rootable 1.2Mb. diskette (this will have your current
        kernel and your current devices (like your tape device) on it.
    c.) mount the bootable-rootable on /mnt w/ "mount /dev/fd096 /mnt" and
        type "cp /bin/restor* /mnt/bin" to copy the restore programs over.
    d.) unmount the floppy w/ "umount /dev/fd096" and reboot your machine.
    e.) reformat your 70Mb. drive
    f.) install a 1 or 2 Mb. DOS partition on your 70Mb. drive, formatted w/ 
        "/S".
    g.) install the base system w/ the installation set from SCO.
    h.) reboot from your bootable-rootable floppy.
    i.) type "restor Rf /dev/<tape> /dev/hd0root" - this restores the tape
        to the root file system on the first hard disk (bet ya didn't know
        about /dev/hd0root on the bootable-rootable did ya? :-))
    j.) your XENIX system is set, now go fix your dos partition to automatically
        change your drive to d: in autoexec.bat.

No Problem! (Or that's what they call me... No Problem Thurmaier :-))

Perhaps SCO has some comments on this also, but I think I got everything.

Good Luck,
Matthew.

P.S.  DOS = Dumb Operating System,
      PCDOS = Partially Complete Operating System
      ... So why do you WANT DOS ANYWAY?
