BIOS SETUP
Main Menu
The ROM BIOS contains a built-in Setup program which allows user to modify the
basic system configuration and hardware parameters. The modified data is 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 causing CMOS data loss. If this happens
you will need install a new CMOS battery and reconfigure your BIOS settings.
To enter the Setup Program :
Power on the computer and press the key during the POST (Power On Self
Test). The BIOS CMOS SETUP UTILITY opens. (Figure 1)
