Gigabyte W480M VISION W - Chapter 2 BIOS Setup; Startup Screen

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
