You may clear the CMOS values by removing the battery:
1. Turn off your computer and unplug the power cord.
2. Gently remove the battery from the battery holder and wait for one minute. (Or use a
metal object like a screwdriver to touch the positive and negative terminals of the battery
holder, making them short for 5 seconds.)
3. Replacethebattery.
4. Plug in the power cord and restart your computer.

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.
•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.)
2-1 Startup Screen
The following startup Logo screen will appear when the computer boots.
(Sample BIOS Version: F1b)
Function Keys
•When the system is not stable as usual, select the Load Optimized Defaults item to set your system to its defaults.
•The BIOS Setup menus described in this chapter are for reference only and may differ by BIOS version.
There are two different BIOS modes as follows and you can use the <F2> key to switch between the two modes.
The Classic Setup mode provides detailed BIOS settings. You can press the arrow keys on your keyboard to move
among the items and press <Enter> to accept or enter a sub-menu. Or you can use your mouse to select the item you
want. Easy Mode allows users to quickly view their current system information or to make adjustments for optimum
performance.InEasyMode,youcanuseyourmousetomovethroughcongurationitems.

2-2 M.I.T.
Whether the system will work stably with the overclock/overvoltage settings you made is dependent on your overall
systemcongurations.Incorrectlydoingoverclock/overvoltagemayresultindamagetoCPU,chipset,ormemory
and reduce the useful life of these components. This page is for advanced users only and we recommend you not to
alter the default settings to prevent system instability or other unexpected results. (Inadequately altering the settings
may result in system's failure to boot. If this occurs, clear the CMOS values and reset the board to default values.)
