BIOS Setting
BIOS Setup Information
BIOS (Basic Input and Output System) include a CMOS SETUP utility which allows user to
configure required settings or to activate certain system features.
The CMOS SETUP saves the configuration in the CMOS SRAM of the motherboard.
When the power is turned off, the battery on the motherboard supplies the necessary power to
the CMOS SRAM.
When the power is turned on, pushing the <Del> button during the BIOS POST (Power-On Self
Test) will take you to the CMOS SETUP screen.
When setting up BIOS for the first time, it is recommended that you save the current BIOS to a
disk in the event that BIOS needs to be reset to its original settings. If you wish to upgrade to a
new BIOS, Award BIOS utility can be used.
Awdflash allows the user to quickly and easily update or backup BIOS without entering the
operating system.
