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.
