Before opening the system, save any open files, exit Windows, turn off the
power of the computer and all attached peripherals, and unplug the
power cord.

Clear CMOS Jumper

The Clear CMOS jumper provides two modes of operation: Normal
mode, and Clear CMOS mode.
Normal mode allows normal access to the BIOS Setup Utility. The Central
Processing Unit (CPU) input clock is forced to remain at 100 MHz (fast
mode), and the Basic Input/Output System (BIOS) uses the User CMOS
settings (as opposed to the System CMOS settings). The CMOS and
NVRAM settings are only cleared if the checksum test returns false.
Access to specific setup fields is controlled by a supervisor password or
user password.
The Clear CMOS mode removes the password that is stored in CMOS. No
other parameters are cleared.
