System Board Jumpers

The system board contains a single, three-pin configuration jumper block
(J5G1). The jumper block is used with the BIOS Setup Maintenance menu for
reconfiguring processor speed when upgrading the system processor. It is also
used for resetting the password and for BIOS recovery.
The following figure shows the location of jumper block J5G1 on the system
board. To reset the jumper block, see the following paragraphs. (The factory-set
jumper settings are included in Section 2, "System Configuration.")

Changing Processor Speed

To change processor speed, the system must be jumpered for Configure mode.
In this mode, the system enters the Maintenance menu when it is restarted.
Use the following steps to change processor speed.
Jumpers are set correctly at the factory for the system
configuration. Only change (or check) the appropriate
jumper setting if upgrading the processor.
1. Access the BIOS Setup utility and record any customized settings. See
"BIOS Setup" in Section 2.
Starting the system in Configure mode resets BIOS settings
to their factory defaults. Before jumpering for Configure
mode, write down any customized BIOS settings for use
after the procedure is completed.
