" The 480 MHz CPUs would require a 120 MHz "clock speed", the Ultra 2
" system board doesn't support that speed - the CPU may run at 400 MHz or
" not at all, 

aren't all usII modules supposed to support x5 operation?  not that i
know of any system that runs that way...  you'd have to find out how
it's triggered, then set something in nvram.  this is after getting
the system to even recognize the 480; while 400s are physically
supported you need a late obp to run them.

the pg on getting faster modules to work on a u30 is
i assume the method, if not the numbers, would work on any system.
