6-4 Setting System Board Jumpers
Processor/Bus Speed Jumpers
The system board must be configured for the frequency of
the installed processor and the corresponding host bus, PCI
bus, and ISA bus frequencies. This jumper should be set
correctly at the factory for your system.
The following procedure explains how to locate and change
the processor speed jumper setting in the unlikely event that
it is not set correctly at the factory.

WARNING
The system power must be off before changing a
jumper setting.
1.
Power off and unplug the system and any peripherals.
2.
Remove the system unit cover (see “Removing the
System Unit Cover” in Chapter 5).

Locate these jumpers on the system board (see
“Locating System Board Jumpers” in the previous
subsection).
You may have to remove any installed expansion boards
to access the jumpers (see “Removing Expansion
Boards” in Chapter 5).

Check the processor/bus speed jumper setting against
the following figure. If necessary, change the jumper
setting by lifting the plastic block and placing it on the
