23) Erasing the CMOS Real Time Clock (RTC) RAM

A Note about Passwords
BIOS Setup programs allow you to specify passwords in the Main menu.
The passwords control access to the BIOS during system startup. The
passwords are not case sensitive. The BIOS Setup program allows you
to specify two separate passwords: a Supervisor password and a User
password.  When disabled, anyone may access all BIOS Setup program
functions. When enabled, the Supervisor password is required for entering
the BIOS Setup program and having full access to all configuration fields.

Forgot the Password?
If you forgot the password, you can clear the password by erasing the CMOS
Real Time Clock (RTC) RAM. The RAM data containing the password
information is powered by the onboard button cell battery. To erase the RTC
RAM: (1) Unplug your computer, (2) Move jumpers from Normal [2-3] to
Clear CMOS [1-2], then immediately return the jumper cap to the Normal
position [2-3], (3) Turn ON your computer, (4) Hold down <Delete> during
bootup and enter BIOS setup to re-enter user preferences.
