    • 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.
    • 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.
    warning
    • 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 "Load Optimized Defaults" section in this chapter or introductions of the battery/clear CMOS jumper in Chapter "Hardware Installation" for how to clear the CMOS values.)

Install the RAID driver and operating system

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

Installing 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 APP 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:

  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.
  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.
  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.

Please visit GIGABYTE's website for details on configuring a RAID array.

Drivers Installation

After you install the operating system, a dialog box will appear on the bottom-right corner of the desktop asking if you want to download and install the drivers and GIGABYTE applications via APP Center. Click Install to proceed with the installation. (In BIOS Setup, make sure Advanced\APP Center Download & Install Confguration\ APP Center Download & Install is set to Enabled.)

When the End User License Agreement dialog box appears, press <Accept> to install APP Center. On the APP Center screen, select the drivers and applications you want to install and click Install.
