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 PZ390A.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
reset the motherboard to the default value. See section 1.1.6 Onboard buttons and
switches 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.

3.11 Updating BIOS
The ASUS website publishes the latest BIOS versions to provide enhancements on system
stability, compatibility,and performance. However, BIOS updating is potentially risky. If
there is no problem using the current version of BIOS, DO NOT manually update the BIOS.
Inappropriate BIOS updating may result to system’s failure to boot. Carefully follow the
instructions in this chapter to update your BIOS when necessary.
Visit http://www.asus.com to download the latest BIOS le for this motherboard.
The following utilities allow you to manage and update the motherboard BIOS setup program.
1. EZ Update: Updates the BIOS in Windows® environment.
2. ASUS EZ Flash 3: Updates the BIOS using a USB ash drive.
3. ASUS CrashFree BIOS 3: Restores the BIOS using the motherboard support DVD or a
USB ash drive when the BIOS le fails or gets corrupted.
3.11.1 EZ Update
The EZ Update is a utility that allows you to update the motherboard BIOS in Windows®
environment.
• EZ Update requires an Internet connection either through a network or an ISP
(Internet Service Provider).
• This utility is available in the support DVD that comes with the motherboard package.

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!

RAID Support

4.1 RAID configurations
The motherboard comes with the Intel® Rapid Storage Technology that supports RAID 0,
RAID 1, RAID 5 and RAID 10 conguration.
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
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 stripes 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.
