Instructions
Award’s ROM BIOS provides a built-in Setup program, which allows
user to modify the basic system configuration and hardware parameters.
The modified data will be stored in a battery-backed CMOS, so that data will
be retained even when the power is turned off. In general, the information
saved in the CMOS RAM will stay unchanged unless there is a configuration
change in the system, such as hard drive replacement or a device is added.
It is possible for the CMOS battery to fail, this will cause data loss in the
CMOS only. If this does happen you will need to reconfigure your BIOS
settings.
