Gigabyte GA-B85M-D3H - Chapter 2 BIOS Setup

15) CLR_CMOS(ClearCMOSJumper)
 UsethisjumpertocleartheBIOScongurations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.
• 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).
Open: Normal
Short: Clear CMOS Values
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.)
