[SunRescue] RE: Sparc 10 and SM512 Module

[Earl Baugh]

Typing "module-info" at the PROM monitor says:
With one of the SM51's I had installed along with the SM512 module it
says: 

MBus    : 40 MHz
SBus    : 20 MHz
CPU#0   : 50 MHz SuperSPARC / SuperCache 3.1/3.3
CPU#2   : 50 MHz SuperSPARC / SuperCache 2.x

The SM512 board is in the bottom MBUS slot, which I believe
is for processors 0 and 1, and the SM51 is in the top MBUS slot 
which I believe is for processors 2 and 3.

If you take out the other SM51, you just lose "CPU#2".
Trying psrinfo gives equivalent results.  Checking the messages
file, also show only 2 cpu's found.

Peter indicated that this module was for the 4/6x0 MP. 
According to Sun, it's also for the SS10:

So it's considered a "spare part" for the SS10.  That implies
to me that it works in it.  What's the latest PROM revision for 
a SS10??  I'm at 2.25 (that's the latest version I have) Could 
that be the issue?  I've booted with a -r and tried also /reconfigure
(grasping at straws here...)  No difference.

Also, James, perhaps you can shed some light, for a SS10 trying to
get to 4 modules, what are the correct ones to get? 
(if the SM512 indeed isn't the correct one...)
