That's what I thought as well.  I recently tried a dual SM512 module in both
boxes and had problems (only single CPU showed up).  So, I was leaning towards
there being some other problem...since the SM512 was retested in a SS20 and
works just fine.  Getting two bad modules in a row (from different sources)
seemed pretty remote.   Also, since the machine boots and has run for a
bit...i.e. booted and started X, install program got to where it was 
"analyzing the disk for upgrade", I was suspecting that there may be a memory 
issue or PROM one.  Last night I tried re-installing the OS, and it ran
for a bit and then paniced.  It got in a loop, so I stopped it. The next boot
(and last one I tried) gave me a "SIMM" error, so I was wondering whether or 
not it needed faster memory.  I'm gonna swap memory around tonight to see 
if that makes a difference (but I dont' have anything that's "faster" than 
standard memory for a SS10..[I've been told that SS20 and some Ultra memory 
works in the SS10's and is a faster speed...]).

Is this different than the info when the machine boots via console?
(I can turn on diag and do that easily enought...) I get output from
the boot process, which seemed to indicate that the module wasn't shot.
