Chapter 2 BIOS Setup
2-1 Startup Screen
The following startup Logo screen will appear when the computer boots.
•When the system is not stable as usual, select the Load Optimized Defaults item to set your system to its defaults.
•The BIOS Setup menus described in this chapter are for reference only and may differ by BIOS version.
There are two different BIOS modes as follows and you can use the <F2> key to switch between the two modes.
Easy Mode allows users to quickly view their current system information or to make adjustments for optimum
performance. In Easy Mode, you can use your mouse to move through conguration items. The Advanced Mode
provides detailed BIOS settings. You can press the arrow keys on your keyboard to move among the items
and press <Enter> to accept or enter a sub-menu. Or you can use your mouse to select the item you want.
Function Keys
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 conguration 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 conguration 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.
•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 "Load Optimized Defaults" section in
this chapter or introductions of the battery/clear CMOS jumper in Chapter 1 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 motherboard driver disc using "Xpress Install" 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. Copy the Hw10 folder under the \BootDrv folder in the driver disc 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. The location of the drivers is as
follows:
\Hw10\RAID\x64
4. Select AMD-RAID Bottom Device rst 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 more software information.
Please visit GIGABYTE's website for more troubleshooting information.
•Before installing the drivers, rst install the operating system.
•After installing the operating system, insert the motherboard driver disc into your optical drive. Click
on the message "Tap to choose what happens with this disc" on the top-right corner of the screen
and select "Run Run.exe." (Or go to My Computer, double-click the optical drive and execute the
Run.exe program.)
"Xpress Install" will automatically scan your system and then list all of the drivers that are recommended to
install. You can click the Xpress Install button and "Xpress Install" will install all of the selected drivers. Or click
the arrow icon to individually install the drivers you need.
