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 are part of the reconfiguration process, along with
running the Computer Setup utility.
The system board jumper settings are identical for the Small Form Factor and Net PC models.
CAUTION: To reduce the risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.
!
WARNING: Be sure to turn off the computer before changing a jumper setting or damage to the system
board can result.
To change the system board jumpers, you must remove the system unit cover. For
assembly and disassembly procedures, refer to Chapter 5.
