Chapter 2 BIOS Setup
BIOS (Basic Input and Output System) records hardware parameters of the system in the CMOS on the
motherboard. Its major functions include conducting the Power-On Self-Test (POST) during system startup,
saving system parameters and loading operating system, etc. BIOS includes a BIOS Setup program that
allowstheusertomodifybasicsystemcongurationsettingsortoactivatecertainsystemfeatures.When
the power is turned off, the battery on the motherboard supplies the necessary power to the CMOS to keep
thecongurationvaluesintheCMOS.
To access the BIOS Setup program, press the <DEL> key during the POST when the power is turned on.

• It is recommended that you not alter the default settings (unless you need to) to prevent system
instability or other unexpected results. Inadequately altering the settings may result in system's
failure to boot. If this occurs, try to clear the CMOS values and reset the board to default values.
(Refer to the "Restore Defaults" section in this chapter or introductions of the battery/clearing
CMOS jumper in Chapter 1 for how to clear the CMOS values.)
