BAT (Battery)
The battery provides power to keep the values (such as BIOS configurations, date, and time information) in the CMOS when the computer is turned off. Replace the battery when the battery voltage drops to a low  level, or the CMOS values may not be accurate or may be lost.

GIGABYTE-B650M-H-Key-Features-Motherboard-fig-33

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.
    • 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.

CLR_CMOS (Clear CMOS Jumper)
Use this jumper to clear the BIOS configuration and reset the CMOS values to factory defaults. To clear the CMOS values, use a metal object like a screwdriver to touch the two pins for a few seconds.

GIGABYTE-B650M-H-Key-Features-Motherboard-fig-34

  • Always turn off your computer and unplug the power cord from the power outlet before clearing the CMOS values.
  • After system restart, go to BIOS Setup to load factory defaults (select Load Optimized Defaults) or manually configure the BIOS settings (please navigate to the “BIOS Setup” page of GIGABYTE’s website for more information).

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 key during the POST when the power is turned on.
  • To upgrade the BIOS, use either the GIGABYTE Q-Flash or Q-Flash Plus utility.
    • 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” page of 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 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 Chapter 2 or navigate to the “BIOS Setup” page of GIGABYTE’s website and search for “Load Optimized Defaults” for how to clear the CMOS values.

Startup Screen:
The following startup Logo screen will appear when the computer boots.

Installing the Operating System and Drivers

Operating System Installation

  • With the correct BIOS settings, you are ready to install the operating system.

  • As some operating systems already include RAID driver, you do not need to install separate RAID driver during the Windows installation process. After the operating system is installed, we recommend that you install all required drivers from the GIGABYTE Control Center to ensure system performance and compatibility. If the operating system to be installed requires that you provide additional RAID driver during the OS installation process, please refer to the steps below:

    • Step 1:
      Go to GIGABYTE’s website, browse to the motherboard model’s web page, download the AMD RAID Preinstall Driver file on the Support\Download\SATA RAID/AHCI page, unzip the file and copy the files to your USB thumb drive.

    • Step 2:
      Boot from the Windows setup disc and perform standard OS installation steps. When the screen requesting you to load the driver appears, select Browse.

    • Step 3:
      Insert the USB thumb drive and then browse to the location of the driver. Select AMD-RAID Bottom Device first and click Next to load the driver. Then select AMD-RAID Controller and click Next to load the driver. Finally, continue the OS installation.GIGABYTE-B650M-H-Key-Features-Motherboard-
