You may clear the CMOS values by removing the battery:

  1. Turn off your computer and unplug the power cord.
  2. Gently remove the battery from the battery holder and wait for one minute. (Or use a metal object like a screwdriver to touch the positive and negative terminals of the battery holder, making them short for 5 seconds.)
  3. Replace the battery.
  4. Plug in the power cord and restart your computer.

caution

  • Always turn off your computer and unplug the power cord before replacing the battery.
  • Replace the battery with an equivalent one. Damage to your devices may occur if the battery is replaced with an incorrect model.
  • Contact the place of purchase or local dealer if you are not able to replace the battery by yourself or uncertain about the battery model.
  • When installing the battery, note the orientation of the positive side (+) and the negative side (-) of the battery (the positive side should face up).
  • Used batteries must be handled in accordance with local environmental regulations.

BIOS Setup

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 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.

  • 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."

caution

  • 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 with caution. 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 the CMOS values and reset the board to default values.
  • Refer to the introductions of the battery/clear CMOS jumper in Hardware Installation Chapter or navigate to the "BIOS Setup" page of GIGABYTE's website and search for "Load Optimized Defaults" for how to clear the CMOS values.

Please visit GIGABYTE's website for details on configuring BIOS Setup.
