[Sunhelp] SS10 mbus upgrade question

[KJH]

I have a Sparcstation 10 with an SM30 cpu; I'd like to upgrade the cpu.
But, my hardware guide only has main board jumper settings for up to 40 mhz
for the processor speed.  How do you set jumpers for hypersparc and other
chips that run at 90 mhz and up?  I'd like to know before I buy one,
possibly without documentation.

I've already upgraded the boot prom to version 2.25, which I understand is
necessary for the higher-speed cpus to work.

Thanks!
