Hehehe.  I have to laugh.  We did the same thing a week ago.  Here's what
you need to do:

1.  Grab your OS distribution media and the IBM AIX Version 3 Installation
Kit instruction manual.

2.  Boot from the distribution media following the instructions in the
manual.

3.  When you get the "AIX 3.1 INSTALLATION AND MAINTENANCE" menu, select
option 5 ("Perform System Maintenance").

4.  Your now in sort of a single user mode.  You need to enter one more 
command to get your disks mounted:  (the magic command)

	/etc/continue hdisk0

When that is done processing, you should be in single user mode.


Be warned, though (as the guy on the phone did AT LEAST a half a dozen times)
IBM can't support anything you do now.  It is recommended that you call your
Service Dude to come up and fix your machine.  But if you know what your doing,
I say go for it.
