Gigabyte GA-Z97M-DS3H - Chapter 2 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conguration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congurationvaluesintheCMOS.
To access the BIOS Setup program, press the <Delete> key during the POST when the power is turned on.
To upgrade the BIOS, use either the GIGABYTE Q-Flash or @BIOS utility.
• Q-Flash allows the user to quickly and easily upgrade or back up BIOS without entering the operating system.
• @BIOS is a Windows-based utility that searches and downloads the latest version of BIOS from the Internet
and updates the BIOS.
