JP26 and JP27 synchronize the processor bus frequency with
the processors speed.
Processor Speed Ratio JP32, JP31, JP30, JP29
The Pentium Pro uses a clock multiplier to run at a
speed faster than the processor bus.
These jumpers match the installed processors speed with
single board computers defined processor speed.
When upgrading processors, you may need to adjust these
jumpers.
