BIOS(BasicInputandOutputSystem)recordshardwareparametersofthesystemintheCMOSonthemotherboard.ItsmajorfunctionsincludeconductingthePower-OnSelf-Test(POST)duringsystemstartup,saving system parameters and loading operating system, etc. BIOS includes a BIOS Setup program that allows the user to modify basic system configuration 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 configuration 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.
Because BIOS flashing ispotentially risky, ifyoudonotencounter problems using thecurrent version ofBIOS, itisrecommended thatyounotflash theBIOS. Toflash theBIOS, doitwithcaution. Inadequate BIOS flashing 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 theCMOS values andreset theboard todefault values. (Refer tothe"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.)
GIGABYTE GA-990FX BIOS Startup Screen
The following startup Logo screen will appear when the computer boots.
Onthemain menu oftheBIOS Setup program, press arrow keystomove among theitems andpress <Enter> to accept or enter a sub-menu. Or you can use your mouse to select the item you want.
This section provides information on the BIOS version, CPU base clock, CPU frequency, memory frequency, total memory size, CPU temperature and CPU voltage, etc.
Whether the system will work stably with the overclock/overvoltage settings you made is dependent on your overall system configurations. Incorrectly doing overclock/overvoltage mayresult indamage toCPU, chipset, ormemory 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.)
M.I.T. Current Status: This screen provides information on CPU/memory frequencies/parameters.
