Setting System Board Jumpers 6-9
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.
If you upgrade your processor, you might need to change
either the processor jumpers or the host bus speed jumper.
The following procedure explains how to change jumper
settings. If necessary, refer to the table at the beginning of
the chapter.
1.
Turn off the power and unplug the system and any
peripherals.
!
WARNING
Turn off the system before you change any jumper
settings.
2.
Remove the access cover (see “Removing the Access
Cover” in Chapter 5).
3.
Locate the Host Bus Frequency jumper (J9C1-C) and
Processor Frequency jumper (J9C1-D) on the system
board (see “Locating Jumpers” in this chapter).
You may have to remove any installed expansion boards
to access the jumpers (see “Removing an Expansion
Board” in Chapter 5).

Check the processor/bus speed jumper settings with
those listed in the table at the front of this chapter and
