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.

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 C8HW.CAP for this
motherboard.

3.11.3 ASUS CrashFree BIOS 3
The ASUS CrashFree BIOS 3 utility is an auto recovery tool that allows you to restore the
BIOS le when it fails or gets corrupted during the updating process. You can restore a
corrupted BIOS le using the motherboard support DVD or a USB ash drive that contains
the BIOS le.
The BIOS le in the motherboard support DVD may be older than the BIOS le published
on the ASUS ofcial website. If you want to use the newer BIOS le, download the le at
https://www.asus.com/support/ and save it to a USB ash drive.
Recovering the BIOS
To recover the BIOS:
1. Turn on the system.
2. Insert the motherboard support DVD to the optical drive, or the USB ash drive
containing the BIOS le to the USB port.
3. The utility automatically checks the devices for the BIOS le. When found, the utility
reads the BIOS le and enters ASUS EZ Flash 3 automatically.
4. The system requires you to enter BIOS Setup to recover the BIOS setting. To ensure
system compatibility and stability, we recommend that you press <F5> to load default
BIOS values.
DO NOT shut down or reset the system while updating the BIOS! Doing so can cause
system boot failure!

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.
