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 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:
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.
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 Settings\IO Ports\APP Center Download & Install Configuration\APP Center Download & Install is set to Enabled.)
When the End User License Agreement dialog box appears, press
Before the installation, make sure the system is connected to the Internet.
