Check out your PROM revision, and compare it with the possibilities for
your system at mbus.sunhelp.org. If you have SM100's in it now, chances
are you're running 2.5 or 2.8, which severely limits your options as far
as CPU's.

Incidentally, I am STILL looking for a PROM upgrade for my 670. If any of
you have mainboards you're not using that have PROMs later than 2.10, I'd
like to hear about it.
