[SunRescue] ultra2 cpu upgrade

[Roger Blake]

I believe jumper pins J2301 must be switched from 2-3 to
1-2 for 300MHz mode. Should be just in front of sbus slot 3
which, looking from the *back* of the motherboard, is the
right side *front* sbus slot. When I upgraded I found this jumper 
tricky to locate and a bit fiddly to change due to it's location.

Memory should automatically configure assuming you remembered to 
fill whole banks of four.

do you have to do anything special, other than an openboot
prom upgrade (if required) to go from 167/512k to 300/2meg
CPUs in an Ultra 2?  motherboard jumpers?  anything?

(tried just swapping cpus and no go..)
