If you need a loop-back connector, then your power-on tests will fail.
You should see a countdown sequence like '7...6...5.." down to 0.  If you
can tell me the last number printed or the led status on the back of the
machine I can tell you want is wrong.  Things to check:
	- keyboard or loop-back connecter is plugged in.
	- same for mouse
	- same for ethernet
	- check that you have the right ethernet port selected.
	- check that your SCSI is properly terminated.

If you get past this OK and are having problems with booting the miniroot,
NetBSD or Ultrix, then I would need to see the results of your boot command.

Hope this helps,

Dean.
