[G4] Sawtooth won't boot in SUM or OF

[CDT]

I'll say it again - You might want to try the Open Firmware resets.   
It's quick, simple, and resolves many flaky problems.  I always start  
with them when I begin having trouble.  Shut down the computer.   
Start it up again and immediately after the chime, press and hold the  
Option, Command, letter "O" and letter "F" keys simultaneously until  
a message appears telling you to release them.  (The machine is now  
booted into Open Firmware).  Then type the following lines exactly  
and press the return key:

reset-nvram (hit the return key)
set-defaults (return)
reset-all (return)

The Mac will restart and should boot normally.  If you still have  
problems, it may be time for a PMU reset.  This link will walk you  
through it.  http://support.apple.com/kb/HT1939  If you want more  
background info, do a google search for "apple PMU reset" which will  
bring up a plethora of links.
