I believe, jumpers don't change anything here (except instability problems
with the 333 MHz one). Now, bus speed is 66MHz, CPU0 runs at 333 MHz which
is factor 5. The 350 MHz CPU1 is thought to run at 100MHz bus speed, i.e.
factor 3.5, hard coded. That means, when running with 66MHz, it runs at
66*3.5=233 MHz.
Since the communication between the processors always happens with the bus
clock of 66MHz, there is no problem. I heard of people who run Celeron's
and P-IIs together...
