BIOS (Basic Input and Output System) includes a CMOS SETUP utility which allows user to
configure required setting or to active certain system features.
The CMOS SETUP saves the configuration in the CMOS SRAM of the mainboard. When the power is turned
off, the battery on the mainboard 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. You can enter the BIOS setup screen by pressing “Ctrl+F1”. 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.
Q-Flash allows the user to quickly and easily update or backup BIOS without entering the operating system.
BIOS is a Window s-based utility that doesn’t required users to boot to DOS before upgrading BIOS but
directly download and update BIOS from the Internet.
