4.5.10 CMOS Data
CMOS is a type of chip on the motherboard that stores system-specific data, such as,
the date and time, and the user and supervisor passwords. The data stored on the
CMOS chip is maintained by the system battery. If the system battery fails, or if it is
removed, the CMOS system-specific data will be cleared and default values used
instead.
Sometimes it is necessary to clear or reset the CMOS, for example, while
troubleshooting, or to reset the passwords. The CMOS chip can be cleared by:
■ Using the Clear CMOS jumper
■ Removing and Installing the System Battery
