important to back up the computer CMOS settings before resetting them in case they are

needed later. Back up is easily done through Computer Setup. See the Computer Setup

(F10) Utility Guide on the Documentation and Diagnostics CD for information on backing up

the CMOS settings.

NOTE Make sure you have disconnected the AC power cord from the wall outlet. The

CMOS switch will not clear CMOS if the power cord is connected.
