The new ASUS UEFI BIOS is a Unied Extensible Interface that complies with UEFI
architecture, offering a user-friendly interface that goes beyond the traditional keyboard-
only BIOS controls to enable a more exible and convenient mouse input. You can easily
navigate the new UEFI BIOS with the same smoothness as your operating system. The
term “BIOS” in this user manual refers to “UEFI BIOS” unless otherwise specied.
BIOS (Basic Input and Output System) stores system hardware settings such as storage
device conguration, overclocking settings, advanced power management, and boot
device conguration that are needed for system startup in the motherboard CMOS. In
normal circumstances, the default BIOS settings apply to most conditions to ensure
optimal performance. DO NOT change the default BIOS settings except in the following
circumstances:
• An error message appears on the screen during the system bootup and requests you
to run the BIOS Setup.
• You have installed a new system component that requires further BIOS settings or
update.
Inappropriate BIOS settings may result to instability or boot failure. We strongly
recommend that you change the BIOS settings only with the help of a trained service
personnel.
• When downloading or updating the BIOS le, rename it as Z270A.CAP for this
motherboard.
• BIOS settings and options may vary due to different BIOS release versions. Please
refer to the latest BIOS version for settings and options.

• The BIOS setup screens shown in this section are for reference purposes only, and
may not exactly match what you see on your screen.
• Ensure that a USB mouse is connected to your motherboard if you want to use the
mouse to control the BIOS setup program.
• If the system becomes unstable after changing any BIOS setting, load the default
settings to ensure system compatibility and stability. Select the Load Optimized
Defaults item under the Exit menu or press hotkey <F5>. See section 3.10 Exit Menu
for details.
• If the system fails to boot after changing any BIOS setting, try to clear the CMOS and

guards drives that do not have password protection by freezing them prior to booting.
If the drive is frozen, a power off or hard reset of your PC must be performed to
proceed with the Secure Erase.
• Locked. SSDs might be locked if the Secure Erase process is either incomplete
or was stopped. This may be due to a third party software that uses a different
password dened by ASUS. You have to unlock the SSD in the software before
proceeding with Secure Erase.

RAID Support

Chapter 4: RAID Support
4.1 RAID configurations
The motherboard supports Intel® Rapid Storage Technology with RAID 0, RAID 1, RAID 5,
and RAID 10 solution.
If you want to install a Windows® operating system to a hard disk drive included in a RAID
set, you have to create a RAID driver disk and load the RAID driver during OS installation.
Refer to section 4.2 Creating a RAID driver disk for details.
4.1.1 RAID definitions
RAID 0 (Data striping) optimizes two identical hard disk drives to read and write data in
parallel, interleaved stacks. Two hard disks perform the same work as a single drive but at a
sustained data transfer rate, double that of a single disk alone, thus improving data access
and storage. Use of two new identical hard disk drives is required for this setup.
RAID 1 (Data mirroring) copies and maintains an identical image of data from one drive to
a second drive. If one drive fails, the disk array management software directs all applications
to the surviving drive as it contains a complete copy of the data in the other drive. This RAID
conguration provides data protection and increases fault tolerance to the entire system. Use
two new drives or use an existing drive and a new drive for this setup. The new drive must be
of the same size or larger than the existing drive.
RAID 5 strips both data and parity information across three or more hard disk drives. Among
the advantages of RAID 5 conguration include better HDD performance, fault tolerance, and
higher storage capacity. The RAID 5 conguration is best suited for transaction processing,
relational database applications, enterprise resource planning, and other business systems.
Use a minimum of three identical hard disk drives for this setup.
RAID 10 is data striping and data mirroring combined without parity (redundancy data) having
to be calculated and written. With the RAID 10 conguration you get all the benets of both
RAID 0 and RAID 1 congurations. Use four new hard disk drives or use an existing drive
and three new drives for this setup.
4-2 Chapter 4: RAID Support
Chapter 4
4.1.2 Installing Serial ATA hard disks
The motherboard supports Serial ATA hard disk drives. For optimal performance, install
identical drives of the same model and capacity when creating a disk array.
To install the SATA hard disks for a RAID conguration:
1. Install the SATA hard disks into the drive bays.
2. Connect the SATA signal cables.
3. Connect a SATA power cable to the power connector on each drive.
4.1.3 Intel® Rapid Storage Technology in UEFI BIOS
To enter the Intel® Rapid Storage Technology in UEFI BIOS:
1. Enter the BIOS Setup during POST.
2. Go to the Advanced menu > PCH Storage Configuration, then press <Enter>.
3. Set the SATA Controller Mode Selection item to [RAID Mode].
4. Go to the Boot menu > CSM (Compatibility Support Module) > Launch CSM, then
set the item to [Disabled].
5. Save your changes and exit the BIOS Setup, then enter the BIOS Setup again.
6. Go to the Advanced menu > Intel(R) Rapid Storage Technology, then press <Enter>
to display the Intel® Rapid Storage Technology menu.
Refer to Chapter 3 for details on entering and navigating through the BIOS Setup.
Due to chipset limitation, when SATA ports are set to RAID mode, all SATA ports run at
RAID mode together.
