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 configuration 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 configuration values in the CMOS.
To access the BIOS Setup program, press the <DEL> key during the POST when the power is turned on. To
see more advanced BIOS Setup menu options, you can press <Ctrl> + <F1> in the main menu of the BIOS
Setup program.

•
BIOS flashing is potentially risky, if you do not encounter problems of using the current BIOS
version, it is recommended that you don't flash the BIOS. To flash the BIOS, do it with caution.
Inadequate BIOS flashing may result in system malfunction.
•
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 "Load Optimized Defaults" section in this chapter or introductions of the battery/
clearing CMOS jumper in Chapter 1 for how to clear the CMOS values.)
