Setting Processor
Speed
B-2 System Board Jumpers and Switches
After you upgrade the processor, the system will automatically
detect the bus speed of your processor and configure the system
to run at maximum bus speed. However, the core speed of the
processor must be configured by changing the SW1 DIP switch
settings on the system board as shown in the following table.
Positions 1 and 6 of SW1 do not affect the speed of the
processor and should not be changed.
CAUTION:
Do not configure the processor to run at a speed
higher than its rated frequency.
Some models will only support a processor with a 66-MHz bus
speed.
