Setting the jumpers

The system board jumpers let you change several system functions.

Jumpers are set to the default positions at the factory. You may need to

change the jumper settings to perform the following functions:

•

Set processor/bus speed settings

•

Clear CMOS memory

Processor speed jumper

The system board supports a range of processor speeds, which are set by

changing jumpers. If you upgrade your processor, you may need to change

jumper settings. The Processor Speed jumper (JP22) configuration block

lets you set the processor speed.

The system automatically detects the bus speed supported by the processor

and uses the jumper settings in conjunction with the detected bus speed to

set the processor speed. If two processors are present and they support

different speeds, the system will operate at the slower speed. Move the

jumper shunts on jumper block JP22 to connect the jumper pins according

to the table below. Processor speeds are given in relation to bus speeds of

66MHz/100MHz.

Caution!

Do not run your processor

at a speed higher than it is

rated or you will cause

irreparable damage to your

system.
