Clear CMOS jumper: CLEAR_CMOS

The onboard CMOS RAM stores system configuration data and has an onboard
battery power supply. To reset the CMOS settings, set the jumper on pins 2 and 3
while the system is off. Return the jumper to pins 1 and 2 afterwards. Setting the
jumper while the system is on will damage the mainboard. The default setting is
on pins 1 and 2.

This option is for setting a password for entering BIOS Setup. When a password
has been set, a password prompt will be displayed whenever BIOS Setup is run.
This prevents an unauthorized person from changing any part of your system
configuration.

There are two types of passwords you can set. A supervisor password and a user
password. When a supervisor password is used, the BIOS Setup program can be
accessed and the BIOS settings can be changed. When a user password is used,
the BIOS Setup program can be accessed but the BIOS settings cannot be
changed.

To set the password, type the password (up to eight characters in length) and
press <Enter
from CMOS memory. The new password will need to be reentered to be
confirmed. To cancel the process press <Esc

To disable the password, press <Enter
A message will show up to confirm disabling the password. To cancel the
process press <Esc

Additionally, when a password is enabled, the BIOS can be set to request the
password each time the system is booted. This would prevent unauthorized use
of the system. See “Security O
