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

[CDT]

That'll teach me to read things carefully.
Question 1.   Does the light on the startup button come on and stay  
on does it only stay on while you are holding the button?
Question 2.   Have you tried to (will the machine let you) reset the  
parameter ram?  Hold the Option, Command, letter "P" and letter "R"  
immediately after the chime on startup.  Hold those four keys until  
the chime sounds at least three (3) more times, then release them and  
allow the machine to continue booting.  (Allowing the repeating the  
chime is supposed to insure that the P- Ram is restored to a pristine  
state.)  That may at least get you to where you can boot into OF or  
try Applejack.
The only other thing I know of to try is a PMU reset.  There is a  
link in my previous post with which you can locate the PMU reset  
procedure for various Apple machines.  If I run across anything else  
that might be helpful, I'll post again.  Hopefully, someone on the  
list has had an experience of this type and can give you some direction.
