7.2 System Board Jumpers

This section provides information for setting jumpers for enabling/disabling passwords and clearing

the configuration (CMOS). When you change a security feature, you will need to reset a jumper and

reconfigure the computer to recognize this change. If the system configuration is incorrect, your

computer may not work properly and you may receive error messages on the screen. Setting the

system board jumpers is part of the reconfiguration process, along with running the Computer Setup

utility.

To change the system board jumpers, you must remove the system unit cover or access

panel. For procedures on removing the system unit cover or access panel, refer to Chapter 5

for desktop computers and to Chapter 6 for minitower computers.

CAUTION:

Be sure to turn off the computer before changing a jumper setting or damage to the system

board can result.

WARNING:

To reduce the risk of personal injury from hot surfaces, allow the internal system components

to cool before touching.
