It might also be a good idea to use a serial console (PuTTY via null-modem
cable, and set to record all printable output), and at the OBP "ok" prompt,
enter the following commands to have insanely-detailed diagnostic tests run:
setenv diag-level max
reset
That might also help with diagnosing the 2nd CPU :-)

Good show! Personally, I'd limit to 472MHz, the UDB chips are often iffy at
120MHz and likely to eventually throw errors under heavy bus load (and that's
when you get data-corruption). If you have SunVTS diag-stress-testing
software
installed, I'd certainly put that overclock through it.
IIRC, *some* of the 'also hidden' commands in OBP are also present in
OpenFirmware, of which source-code is freely available. As for the 2nd-CPU
problem, getting latest OBP firmware might help.

fantastic info. Thank you.

I found if I went straight to 480 the machine locked up.....
so booting the machine and logging in....
Sun Microsystems Inc. SunOS 5.8 Generic February 2000
# psrinfo -v
Status of processor 0 as of: 11/12/19 22:12:37
Processor has been on-line since 11/12/19 21:56:52.
The sparcv9 processor operates at 480 MHz,
and has a sparcv9 floating point processor.
and
# /usr/platform/sun4u/sbin/prtdiag -v
System Configuration: Sun Microsystems sun4u (UltraSPARC-II 480MHz)
System clock frequency: 120 MHz
Memory size: 1024 Megabytes
========================= CPUs =========================
Run Ecache CPU CPU
Brd CPU Module MHz MB Impl. Mask
--- --- ------- ----- ------ ------ ----
0 0 0 480 4.0 US-II 1.0
so it can be seen at the OS level as a 480Mhz CPU.....will run this for a
while and see what happens.
I wonder if there is a way to get the 8Mb of cache visible instead of the 4Mb
Inserting the second CPU and the system hangs after identifying the graphics
card....guess the CPU has issues. (unless there is another mask hack or some
such?)
also is there a list of "Hidden" OBP Commands?
cheers
