Gigabyte GA-X150M-PLUS WS - 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 upgrade the BIOS, use either the GIGABYTE Q-Flash or @BIOS utility.

• @BIOS is a Windows-based utility that searches and downloads the latest version of BIOS from the Internet
and updates the BIOS.

• 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
