Gigabyte GA-H97M-HD3 - Chapter 2 BIOS Setup; Clear CMOS Jumper

- 17 -
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.
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inChapter1forhowtocleartheCMOSvalues.)
13) CLR_CMOS(ClearCMOSJumper)
 UsethisjumpertocleartheBIOScongurationandresettheCMOSvaluestofactorydefaults.Toclear
the CMOS values, use a metal object like a screwdriver to touch the two pins for a few seconds.
Open: Normal
Short: Clear CMOS Values
• Always turn off your computer and unplug the power cord from the power outlet before clearing
the CMOS values.
• Aftersystemrestart,gotoBIOSSetuptoloadfactorydefaults(selectLoadOptimizedDefaults)or
manuallyconguretheBIOSsettings(refertoChapter2,"BIOSSetup,"forBIOScongurations).
