I believe there should not be a problem with this device assuming the
hardware settings are correct on the board.  A few months ago I helped
a customer install Ultrix-32 1.2 on a uVAX with the same controller.
Suggestions: 

	1.  Make sure that the board is set up to look like a DHV
		(!!!!) and not a DHU  (see the Emulex manual -- you
		may need to change a few switches... we did.)

	2. remove the terminal nodes in /dev -- assuming you only have
		the "dhv", "rm /dev/tty?*" should do it.

	3. remake the terminal nodes -- "cd /dev; MAKEDEV dhu0 dhu1"
		(make sure you use the MAKEDEV script!)

At this point try it again...
