Well the DOS-73 board isn't running AT&T MSDOS.  It's running a special
version (I assume developed at Alloy) for the DOS-73 board.  It gives the
look and feel of MSDOS, but it's missing things.  It claims to be version 3.1,
which it might really be close to.  I doubt one could take MSDOS 3.30a or
4.01 and reconfigure the system.  Never tried it.  If some brave sole
wants to ... I'd suggest, inserting the MSDOS 3.30a disk, boot off drive
"A:" and then see if it works.

I don't remember if you can boot disks, but if you can't you could make
a copy of /usr/lib/ua/DOS/dvd001 (or whatever that path is) for virtual
drive C: ... and then issue these commands:

	C>A:
	A>SYS C:

... Let me know if it works! :-)
