Xenix 2.3 and MS-DOS 3.3 - together?

[Chip Salzenberg]

Recently we've been trying to put SCO Xenix 2.3 and MS-DOS 3.3 on the
same disk.  Specifically, we've got a 32M DOS partition, followed by a
96M secondary DOS partition with three logical drives, followed by a Xenix
partition for the rest of the disk.  It all works.

Sorta.

If the Xenix partition is active and the Boot prompt appears, typing "dos"
doesn't get to DOS.  And when we use Xenix "fdisk" to make the DOS partition
active, >nothing< gets booted.  A clue is that the DOS partition shows up
as partition #4, even though it was created first; but we don't know why.

Has anyone gotten MS-DOS 3.3 to be the default boot on a shared Xenix/DOS
disk?  I'd really like to know.

E-Mail, if you like; I'll summarize.
