Hi, I am playing with my operating system in order to fix a problem I have with IP5 on high load. The lboot -t nicely produces a new kernel, asks whether I want to reconfigure the system upon startup, and is apparently o.k. The only thing which puzzles me is that I am getting in trouble with the panic messages if I accidentially did something wrong. The machine dies, and hangs, without RESET being active... I need to power off the machine in order to get the PROM prompt. I then load the inst, spawn a sh and rename my save file to /root/unix in order to be able to boot. Question: In early versions of PROM, there was a hint how to boot a different file than /unix on the system disk. I didn't find that info somewhere now in the current documentation (3.3). How to boot a file other than /unix ? Merci Reinhard

To boot from a SCSI disk, I use: boot dksc(0,1,0)unix.test I too spent quite a while once trying to figure out how to do this. Sure would be nice if there was a _real_ index for all these #!#? manuals. -- ##################################################################### # CompuServe: >INTERNET:uunet.UU.NET!ki!dwatts Dan Watts # # UUCP : ...!uunet!ki!dwatts Ki Research, Inc. # ############### New Dimensions In Network Connectivity ##############

When you're at the ">>" prompt, tell the system to boot the file that you have saved. For example if you have a scsi root disk, and your saved unix file is called unix.sav, type: >>boot dksc(0,1,0)/unix.sav The dksc means use a scsi device, the first 0 means controller 0, the 1 means device 1 (the default main disk), and the last 0 means partition 0 (SGI's default root partition). >Merci >Reinhard De rien.
