English
Chapter 2 BIOS Setup
BIOS (Basic Input and Output System) includes 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. 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. If you wish to upgrade to a new BIOS, either
Gigabyte's Q-Flash or @BIOS utility can be used.
Q-Flash allows the user to quickly and easily update or backup BIOS without entering the operating system.
@BIOS is a Windows-based utility that does not require users to boot to DOS before upgrading BIOS but
directly download and update BIOS from the Internet.

in the system.
The value of the base memory is typically 512K for systems with 512K memory installed on
the motherboard, or 640K for systems with 640K or more memory installed on the motherboard.
