   This is how to boot into single user mode on the Iris 4d/20.
We (make that I) have had to do it numerous times,,,

      When you start up the system you will get the following
message (or close enough)..

     Hit [ESC] to to go to maintenance menu.. 
  
 Hit ESC. There should now be a menu with 5 or 6 options. You want
to choose option 5 (Comannd line Monitor).
 At this point your prompt will ge a '>'.. now enter the following..

 boot dksc(,1,)unix initstate=s

 This will fire up the system again.. You have to hit ESC AGAIN
when asked for maintenance menu and then hit 5 AGAIN for command line
monitor and then re-enter the 'boot' command. For some reason the 4d/20
forgets the first time around that you want single user mode.

   When asked for ESC the next time.. let it go.. You will now be in
single user mode as root. Do what you have to do then enter

 sync
 sync
 sync
 init 0

 this will bring down the system and you can then restart it.

   Hope this helps.
