* You need to unset the non-volatile ram variable "root" in the prom.  You
* can do this by getting into prom manual mode and typing:
* 
* 	unsetenv root

Hmmmmmmm......

Re: Advanced Configurations

Please.

1) keep a notebook.  Log all changes.  Use a was/is/why triplet
 to ensure the ability to return to a sane set of values.
 Review and summarize the notes often.

2) save factory values in the notebook prior to
 changing anything.  If the files are on line print them to
 paper.  Remember, if you have a problem you will not be able 
 to read them  :-)

3) Back up and verify your backups prior to any upgrade.  There is
 always a chance that some general clean up by SGI,  may step on your 
 local changes.  Back up in ways you understand and can verify.  
 Always back up your own work.

4) Have a back up system administrator.  Work with this person
 at all times.  Share information and discuss changes prior 
 to doing.  

5) Plan to have extra time when installing any option or upgrade.
 Verify devices and mounts prior to installing software.
 
6) Avoid going up the down stair case.  The more users and more
 critical the machine the more important it is to avoid special
 case handling.  Do read the book (Up the Down Staircase) it 
 is funny and has nothing to do with computers.

7) Go for it.
