Setting system board 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
•
SHM mode
Processor speed jumper
The system board supports a range of processor speeds, which are set by
changing jumper shunts on the block. If you upgrade your processor, you
may need to change jumper settings. The JP22 jumper configuration block
lets you set the processor speed.
If two processors are present and they support different speeds, set the
processor speed jumper to the slower speed. Move the jumper shunts on
jumper block JP22 to connect the jumper pins according to the following
table.
