Gigabyte B660M GAMING X AX [2/28] Bios setup

- 2 -

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.

For instructions on using the Q-Flash and @BIOS utilities, please navigate to the "Unique Features" page of

GIGABYTE's website and search for "BIOS Update Utilities."

• 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 introductions of the battery/clear CMOS jumper/button in user's manual or refer to the

"Load Optimized Defaults" section for how to clear the CMOS values.
