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.
For instructions on using the Q-Flash and @BIOS utilities, refer to Chapter 4, "BIOS Update Utilities."
Chapter 2 BIOS Setup
• BecauseBIOSashingispotentiallyrisky, ifyoudonotencounterproblemsusingthecurrent
versionofBIOS,itisrecommendedthatyounotashtheBIOS.ToashtheBIOS,doitwith
caution.InadequateBIOSashingmayresultinsystemmalfunction.
• Itisrecommendedthatyounotalterthedefaultsettings(unlessyouneedto)topreventsystem
instability or other unexpected results. Inadequately altering the settings may result in system's
failure to boot. If this occurs, try to clear the CMOS values and reset the board to default values.
(Refertothe"LoadOptimizedDefaults"sectioninthischapterorintroductionsofthebattery/clear
CMOS jumper/buttoninChapter1forhowtocleartheCMOSvalues.)
