System Utilities Chapter 2 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 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. wxyz e ^ Item { } l t u Description Move to selection Select Item Main Menu: Quit and not save changes into CMOS Status Page Setup Menu and Option Page Setup Menu, Exit current page and return to Main Menu.
