BIOS Setup
BIOS (Basic Input and Output System) records hardware parameters of the system in the CMOS on themotherboard. 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 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 tokeep 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 Q-Flash Plus.
•• Q-Flash allows the user to quickly and easily upgrade or back up BIOS without entering the operating system.
•• Q-Flash Plus allows you to update the BIOS when your system is off (S5 shutdown state). Save the latest
BIOS on a USB thumb drive and plug it into the dedicated port, and then you can now flash the BIOS
automatically by simply pressing the Q-Flash Plus button.
For instructions on using the Q-Flash and Q-Flash Plus utilities, please navigate to the "Unique Features" pageof GIGABYTE's website and search for "BIOS Update Utilities."•• Because BIOS flashing is potentially risky, if you do not encounter problems using the current
version of BIOS, it is recommended that you not flash the BIOS. To flash the BIOS, do it withcaution. Inadequate BIOS flashing may result in system malfunction.
•• It is recommended that you not alter the default settings (unless you need to) to prevent systeminstability 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.
