2.3 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.

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.

BIOS settings and options may vary due to different BIOS release versions. Please refer to

the latest BIOS version for settings and options.

The new ASUS UEFI BIOS is a Unied 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 specied.

BIOS (Basic Input and Output System) stores system hardware settings such as storage

device conguration, overclocking settings, advanced power management, and boot

• Secure Erase is only supported on Intel SATA port. For more information about Intel

SATA ports, refer to section 1.1.2 Motherboard layout of this manual.

Status definition:

• Frozen. The frozen state is the result of a BIOS protective measure. The BIOS 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

dened by ASUS. You have to unlock the SSD in the software before proceeding with

Secure Erase.

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 ofcial 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!

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

conguration 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 conguration include better HDD performance, fault tolerance, and

higher storage capacity. The RAID 5 conguration 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 conguration you get all the benets of both

RAID 0 and RAID 1 congurations. 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 conguration:

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.
