USB BIOS Flashback
USB BIOS Flashback allows you to easily update the BIOS without entering the existing
BIOS or operating system. Simply insert a USB storage device to the USB port, press the
USB BIOS Flashback button for three seconds, and the BIOS is updated automatically.
To use USB BIOS Flashback:
1. Insert a USB storage device to the USB Flashback port.
We recommend you to use a USB 2.0 storage device to save the latest BIOS version for
better compatibility and stability.
2. Visit https://www.asus.com/support/ and download the latest BIOS version for this
motherboard.
3. Rename the le as C8F.CAP, then copy it to your USB storage device.
4. Shut down your computer.
5. Press the BIOS Flashback button for three seconds until the Flashback LED blinks
three times, indicating that the BIOS Flashback function is enabled.
• Do not unplug portable disk, power system, or press the CLR_CMOS button while
BIOS update is ongoing, otherwise update will be interrupted. In case of interruption,
please follow the steps again.
• If the light ashes for ve seconds and turns into a solid light, this means that
the BIOS Flashback is not operating properly. This may be caused by improper
installation of the USB storage device and lename/le format error. If this scenario
happens, please restart the system to turn off the light.
• Updating BIOS may have risks. If the BIOS program is damaged during the process
and results to the system’s failure to boot up, please contact your local ASUS Service
Center.
For more BIOS update utilities in BIOS setup, refer to the section 3.11 Updating BIOS in
Chapter 3.

2.4 Starting up for the first time
1. After making all the connections, replace the system case cover.
2. Ensure that all switches are off.
3. Connect the power cord to the power connector at the back of the system chassis.
4. Connect the power cord to a power outlet that is equipped with a surge protector.
5. Turn on the devices in the following order:
a. Monitor
b. External SCSI devices (starting with the last device on the chain)
c. System power
6. After applying power, the system power LED on the system front panel case lights
up. For systems with ATX power supplies, the system LED lights up when you press
the ATX power button. If your monitor complies with the “green” standards or if it has
a “power standby” feature, the monitor LED may light up or change from orange to
green after the system LED turns on.
The system then runs the power-on self tests (POST). While the tests are running,
the BIOS beeps (refer to the BIOS beep codes table) or additional messages appear
on the screen. If you do not see anything within 30 seconds from the time you turned
on the power, the system may have failed a power-on test. Check the jumper settings
and connections or call your retailer for assistance.

2.5 Turning off the computer
While the system is ON, press the power button for less than four seconds to put the system
on sleep mode or soft-off mode, depending on the BIOS setting. Press the power button
for more than four seconds to let the system enter the soft-off mode regardless of the BIOS
setting.

Chapter 3: BIOS Setup
3.1 Knowing BIOS
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 C8F.CAP for this motherboard.

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
reset the motherboard to the default value. See section 2.3.1 Rear I/O connection
for information on how to erase the RTC RAM via the Clear CMOS button.
• The BIOS setup program does not support the Bluetooth devices.
Please visit ASUS website for the detailed BIOS content manual.

Chapter 4: RAID Support
4.1 AMD RAID Array configurations
The motherboard comes with the RaidXpert2 Conguration Utility that supports Volume,
RAIDABLE, RAID 0, RAID 1, and RAID 10 (depends on system licensing) congurations.
For more information on conguring your RAID sets, please refer to the RAID
Configuration Guide which you can nd at https://www.asus.com/support.
4.1.1 RAID definitions
Volume provides the ability to link-together storage from one or several disks, regardless
of the size of the space on those disks. This conguration is useful in scavenging space on
disks unused by other disks in the array. This conguration does not provide performance
benets or data redundancy, disk failure will result in data loss.
RAIDABLE arrays (also known as RAID Ready) are a special type of Volume (JBOD) that
allows the user to add more storage space or create a redundant array after a system is
installed. RAIDABLE arrays are created using Option ROM, UEFI, or rcadm.
The ability to create RAIDABLE arrays may vary per system.
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 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.
