•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.

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.
