WARNING: 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 (refer to Chapter 2, "BIOS Setup," for BIOS configurations).

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 the 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.
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 the 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.)

Startup Screen

The following startup Logo screen will appear when the computer boots.(Sample BIOS Version: E1)

There are two different BIOS modes as follows, and you can use the <F2> key to switch between the two modes. The Classic Setup 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.

Configuring a RAID Set

RAID Levels

Before you begin, please prepare the following items:

At least two SATA hard drives or SSDs. (Note 1) (To ensure optimal performance, it is recommended that you use two hard drives with identical model and capacity). (Note 2)
Windows setup disk.
Motherboard driver disk.
A USB thumb drive.

Configuring the Onboard SATA Controller

A. Installing SATA hard drive(s) in your computer Install the hard drives/SSDs in the Intel® Chipset controlled connectors on the motherboard. Then connect the power connectors from your power supply to the hard drives.

B. Configuring SATA controller mode in BIOS Setup Make sure to configure the SATA controller mode correctly in system BIOS Setup. Steps:

Go to Peripherals\SATA And RST Configuration, make sure SATA Controller(s) is enabled. To create RAID, set SATA Mode Selection to Intel RST Premium With Intel Optane System Acceleration. Then save the settings and restart your computer. Note: When using a PCIe SSD, make sure to set the Use RST Legacy OROM item under Peripherals\SATA And RST Configuration to Disabled. Then depending on the M.2 connector you use, set the corresponding PCIe Storage Dev on Port XX item to RST Controlled. Finally, save the settings and exit BIOS Setup.
To use the EZ RAID feature, follow the steps in "C-1." To configure UEFI RAID, follow the steps in "C-2." To enter the legacy RAID ROM, refer to "C-3" for more information. Finally, save the settings and exit BIOS Setup.

The BIOS Setup menus described in this section may differ from the exact settings for your motherboard. The actual BIOS Setup menu options you will see shall depend on the motherboard you have and the BIOS version.

Using EZ RAID

GIGABYTE motherboards provide you with the EZ RAID feature, allowing you to quickly configure a RAID array with simplified steps. Steps:

After restarting the computer, enter the BIOS Setup and go to Peripherals. Press <Enter> on the EZ RAID item. Select the type of hard drives you use for RAID in the Type tab and then press <Enter>.
Go to the Mode tab to select a RAID level. RAID levels supported include RAID 0, RAID 1, RAID 10, and RAID 5 (the selections available depend on the number of hard drives being installed). Then press <Enter> to move to the Create tab. Click Proceed to begin.
After completing, you'll be brought back to the Intel(R) Rapid Storage Technology screen. Under RAID Volumes, you can see the new RAID volume. To see more detailed information, press <Enter> on the volume to check for information on RAID level, stripe block size, array name, and array capacity, etc. (Note 1) An M.2 PCIe SSD cannot be used to set up a RAID set either with an M.2 SATA SSD or a SATA hard drive. (Note 2) Refer to "1-7 Internal Connectors," for the installation notices for the M.2 and SATA connectors.

UEFI RAID Configuration Steps:

In BIOS Setup, go to BIOS and set CSM Support to Disabled. Save the changes and exit BIOS Setup.
After the system reboot, enter BIOS Setup again. Then enter the Peripherals\Intel(R) Rapid Storage Technology sub-menu.
On the Intel(R) Rapid Storage Technology menu, press <Enter> on Create RAID Volume to enter the Create RAID Volume screen. Enter a volume name with 1~16 letters (letters cannot be special characters) under the Name item and press <Enter>. Then, select a RAID level. RAID levels supported include RAID 0, RAID 1, RAID 10, and RAID 5 (the selections available depend on the number of hard drives being installed). Next, use the down arrow key to move to Select Disks.
Under Select Disks item, select the hard drives to be included in the RAID array. Press the <Space> key on the hard drives to be selected (selected hard drives are marked with "X"). Then set the stripe block size. The stripe block size can be set from 4 KB to 128 KB. Once you have selected the stripe block size, set the volume capacity.
After setting the capacity, move to Create Volume and press <Enter> to begin.
After completing, you'll be brought back to the Intel(R) Rapid Storage Technology screen. Under RAID Volumes, you can see the new RAID volume. To see more detailed information, press <Enter> on the volume to check for information on RAID level, stripe block size, array name, and array capacity, etc.

Configuring Legacy RAID ROM

Enter the Intel legacy RAID BIOS setup utility to configure a RAID array. Skip this step and proceed with the installation of the Windows operating system for a non-RAID configuration. Steps:

In BIOS Setup, go to BIOS and set CSM Support to Enabled and Storage Boot Option Control to Legacy. Next, go to Peripherals\SATA And RST Configuration and make sure Use RST Legacy OROM is set to Enabled. Save the changes and exit BIOS Setup. After the POST memory test begins and before the operating system boot begins, look for a message that says "Press <Ctrl-I> to enter Configuration Utility". Press <Ctrl> + <I> to enter the RAID Configuration Utility.
After you press <Ctrl> + <I>, the MAIN MENU screen will appear. If you want to create a RAID array, select Create RAID Volume in MAIN MENU and press <Enter>.
After entering the CREATE VOLUME MENU screen, enter a volume name with 1~16 letters (letters cannot be special characters) under the Name item and press <Enter>. Then, select a RAID level. RAID levels supported include RAID 0, RAID 1, RAID 10, and RAID 5 (the selections available depend on the number of hard drives being installed). Press <Enter> to proceed.
Under Disks item, select the hard drives to be included in the RAID array. If only two hard drives are installed, they will be automatically assigned to the array. Set the stripe block size if necessary. The stripe block size can be set from 4 KB to 128 KB. Once you have selected the stripe block size, press <Enter>.
Enter the array capacity and press <Enter>. Finally press <Enter> on the Create Volume item to begin creating the RAID array. When prompted to confirm whether to create this volume, press <Y> to confirm or <N> to cancel.
When completed, you can see detailed information about the RAID array in the DISK/VOLUME INFORMATION section, including the RAID level, stripe block size, array name, and array capacity, etc. To exit the RAID BIOS utility, press <Esc> or select 6. Exit in MAIN MENU.

Install the SATA RAID/AHCI 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 Intel® RAID/AHCI driver, you do not need to install separate RAID/AHCI driver during the Windows installation process. After the operating system is installed, we recommend that you install all required drivers from the motherboard driver disk using "Xpress Install" to ensure system performance and compatibility. If the operating system to be installed requires that you provide additional SATA RAID/AHCI driver during the OS installation process, please refer to the steps below:

Copy the IRST folder under \Boot in the driver disk to your USB thumb drive.
Boot from the Windows setup disk and perform standard OS installation steps. When the screen requesting you to load the driver appears, select Browse.
Then browse to the USB flash drive and select the location of the driver. The location of the driver is as follows: \IRST\f6flpy-x64
When a screen as shown, select Intel Chipset SATA RAID Controller and click Next to load the driver and continue the OS installation.
