2-6 System Info. This section provides information on your motherboard model and BIOS version. You can also select the default language used by the BIOS and manually set the system time. && Access Level Displays the current access level depending on the type of password protection used. (If no password is set, the default will display as Administrator.
2-7 Boot && Bootup NumLock State Enables or disables Numlock feature on the numeric keypad of the keyboard after the POST. (Default: On) && Security Option Specifies whether a password is required every time the system boots, or only when you enter BIOS Setup. After configuring this item, set the password(s) under the Administrator Password/User Password item. Setup A password is only required for entering the BIOS Setup program.
&& USB Support Disable Link All USB devices are disabled before the OS boot process completes. Full Initial All USB devices are functional in the operating system and during the POST. (Default) Partial Initial Part of the USB devices are disabled before the OS boot process completes. This item is configurable only when Fast Boot is set to Enabled or Ultra Fast. This function is disabled when Fast Boot is set to Ultra Fast.
&& Administrator Password Allows you to configure an administrator password. Press on this item, type the password, and then press . You will be requested to confirm the password. Type the password again and press . You must enter the administrator password (or user password) at system startup and when entering BIOS Setup. Differing from the user password, the administrator password allows you to make changes to all BIOS settings.
2-8 Save & Exit && Save & Exit Setup Press on this item and select Yes. This saves the changes to the CMOS and exits the BIOS Setup program. Select No or press to return to the BIOS Setup Main Menu. && Exit Without Saving Press on this item and select Yes. This exits the BIOS Setup without saving the changes made in BIOS Setup to the CMOS. Select No or press to return to the BIOS Setup Main Menu.

3. 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 on the volume to check for information on RAID level, stripe block size, array name, and array capacity, etc. C-2. UEFI RAID Configuration Steps: 1. In BIOS Setup, go to Boot and set CSM Support to Disabled. Save the changes and exit BIOS Setup. 2. After the system reboot, enter BIOS Setup again.
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.
A-2: Installation in Intel RST Premium With Intel Optane System Acceleration mode If the SATA controller has been configured in Intel RST Premium With Intel Optane System Acceleration mode, please follow the steps below: 1. After system restarts, go to the BIOS Setup, make sure CSM Support under the Boot menu is disabled. 2. Go to Settings\IO Ports\SATA And RST Configuration and make sure Use RST Legacy OROM is disabled and RST Control PCIe Storage Devices is set to Manual.
