We have a Personal Iris which we are trying to set up to run NFS. This is not a particular problem - we managed it a couple of days ago before our power supply blew up... But when we re-installed it today, we didn't set things up quite right and when we booted the machine, it went to sleep on the NFS mounts. What we want to be able to do is boot single user so that we can edit the fstab, then reboot and try to fix things. Is it possible to boot a Personal Iris single user (given that it is set up to boot multi-user through inittab or whatever), or has this feature been automated right out of the system? This information will no doubt be useful as we continue trying to integrate this beast in our Sun-ful environment. Thanks ian -- Ian S.

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. ============================================================================== Trevor Paquette/GraphicsLand, Calgary, Alberta UUCP: uunet!{ubc-cs,utai,alberta}!calgary!paquette ICBM:51 03 N/114 05 W Luminous beings we are, not this crude matter
