User Manual

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.)
