Clearing CMOS
If you need to erase configuration information, you must move the CMOS jumper.
See the illustration in “Recovering BIOS” on page 17 for the location of the CMOS
jumper.
The default position is a jumper installed on pins 1 and 2. Before you change the
position of this jumper, you
must turn off the computer and attached devices, and
disconnect all external cables and power cords. Remove the cover and then move
the jumper to pins 2 and 3.
After moving the jumper, wait at least 5 minutes for the CMOS information to
clear.
Changing the position of this jumper erases all configuration and setup
information, including the power-on and administrator passwords. Therefore, you
must reconfigure the computer after clearing CMOS memory (see Chapter 4,
“Configuration” on page 23). If possible, record your computer configuration
information
before moving the CMOS jumper.
After you clear the CMOS information, move the jumper back to it normal position
(pins 1 and 2). Reconnect the external cables and power cords; then, turn on the
attached devices and the computer.
