With the use of the power connector, the power supply can supply enough stable power to all the
components on the motherboard. Before connecting the power connector, first make sure the
power supply is turned off and all devices are properly installed. The power connector possesses
a foolproof design. Connect the power supply cable to the power connector in the correct orientation.
The 12V power connector mainly supplies power to the CPU. If the 12V power connector is not
connected, the computer will not start.
• To meet expansion requirements, it is recommended that a power supply that can withstand
high power consumption be used (400W or greater). If a power supply is used that does not
provide the required power, the result can lead to an unstable or unbootable system.
• The main power connector is compatible with power supplies with 2x10 power
connectors. When using a 2x12 power supply, remove the protective cover from the
main power connector on the motherboard. Do not insert the power supply cable into pins
under the protective cover when using a 2x10 power supply.

The motherboard has a 4-pin CPU fan header (CPU_FAN) and a 3-pin system fan header
(SYS_FAN). Each fan header supplies a +12V power voltage and possesses a foolproof insertion
design. When connecting a fan cable, be sure to connect it in the correct orientation. Most fans are
designed with color-coded power connector wires. A red power connector wire indicates a
positive connection and requires a +12V voltage. The black connector wire is the ground wire. The
motherboard supports CPU fan speed control, which requires the use of a CPU fan with fan speed
control design. For optimum heat dissipation, it is recommended that a system fan be installed
inside the chassis.

BIOS Setup
BIOS (Basic Input and Output System) records hardware parameters of the system in the CMOS on the
motherboard. Its major functions include conducting the Power-On Self-Test (POST) during system
startup, saving system parameters and loading operating system, etc. BIOS includes a BIOS Setup
program that allows the user to modify basic system configuration settings or to activate certain system
features. When the power is turned off, the battery on the motherboard supplies the necessary power
to the CMOS to keep the configuration values in the CMOS.
To access the BIOS Setup program, press the <Delete> key during the POST when the power is turned
on. To see more advanced BIOS Setup menu options, you can press <Ctrl> + <F1> in the main menu
of the BIOS Setup program.
To upgrade the BIOS, use either the GIGABYTE Q-Flash or @BIOS utility.
Q-Flash allows the user to quickly and easily upgrade or back up BIOS without entering the
operating system.
@BIOS is a Windows-based utility that searches and downloads the latest version of BIOS from the
Internet and updates the BIOS.
For instructions on using the Q-Flash and @BIOS utilities, refer to Chapter 4, "BIOS Update Utilities."
• Because BIOS flashing is potentially risky, if you do not encounter problems using the current
version of BIOS, it is recommended that you not flash the BIOS. To flash the BIOS, do it with
caution. Inadequate BIOS flashing may result in system malfunction.
• BIOS will emit a beep code during the POST. Refer to Chapter 5, "Troubleshooting," for the
beep codes description.
• It is recommended that you not alter the default settings (unless you need to) to prevent system
instability or other unexpected results. Inadequately altering the settings may result in
system's failure to boot. If this occurs, try to clear the CMOS values and reset the board to
default values. (Refer to the "Load Optimized Defaults" section in this chapter or introductions
of the battery/clearing CMOS jumper in Chapter 1 for how to clear the CMOS values.)

This motherboard incorporates cable diagnostic feature designed to detect the status of the attached LAN
cable. This feature will detect cabling issue and report the approximate distance to the fault or short.
Refer to the following information for diagnosing your LAN cable:
When No LAN Cable Is Attached...
If no LAN cable is attached to the motherboard, the Status fields of all four pairs of wires will show
Open and the Length fields show 0.0m, as shown in the figure above.

BIOS Setup
English
SATA Port 1/3 Set to
English
When LAN Cable Is Functioning Normally...
If no cable problem is detected on the LAN cable connected to a Gigabit hub or a 10/100 Mbps hub,
the following message will appear:
Start detecting at Port.....
Link Detected --> 100Mbps
Cable Length= 30m
Link Detected
Displays transmission speed
Cable Length
Displays the approximate length of the attached LAN cable.
Note: The Gigabit hub will only operate at a speed of 10/100Mbps in MS-DOS mode; it will operate
at a normal speed of 10/100/1000Mbps in Windows mode or when the LAN Boot ROM is activated.
When a Cable Problem Occurs...
If a cable problem occurs on a specified pair of wires, the Status field will show Short and
thenlength shown will be the approximate distance to the fault or short.
Example: Pair1-2 Status = Short / Length
=
1.6m
Explanation: A fault or short might occur at about 1.6m on Pair 1-2.
Note: Pair 4-5 and Pair 7-8 are not used in a 10/100 Mbps environment, so their Status fields will
show Open, and the length shown is the approximate length of the attached LAN cable.

NTFS, FAT32, and FAT16 file systems, Xpress Recovery2 can back
up data on PATA and SATA hard drives and restore it.
Before You Begin:
• Xpress Recovery2 will check the first physical hard drive* for the operating system. Xpress
Recovery2 can only back up/restore the first physical hard drive that has the operating system
installed.
• As Xpress Recovery2 will save the backup file at the end of the hard drive, make sure to leave
enough unallocated space in advanced (10 GB or more is recommended; actual size requirements vary, depending on the amount of data).
• It is recommended to back up your system soon after the operating system and drivers are
installed.
• The amount of data and hard drive access speed may affect the speed at which the data is backed
up/restored.
• It takes longer to back up a hard drive than to restore it.
System Requirements:
•
•
•
•
Intel ® x86 platform
At least 64 MB of system memory
VESA compatible graphics card
Windows ® 2000 with SP3 or later; Windows® XP with SP1 or later
• Xpress Recovery and Xpress Recovery2 are different utilities. For example, a backup file
created with Xpress Recovery cannot be restored using Xpress Recovery2.
• USB hard drives are not supported.
• Hard drives in RAID/AHCI mode are not supported.
"*" Xpress Recovery2 checks the first physical hard drive in the following sequence: The first PATA
IDE connector, the second PATA IDE connector, the first SATA connector, the second SATA
connector and so forth. For example, when hard drives are attached to the first IDE and the first
SATA connectors, the hard drive on the first IDE connector is the first physical drive. When hard
drives are attached to the first and second SATA connectors, the hard drive on the first SATA
connector is the first physical drive.

Installation and Configuration
(The following procedure uses Windows XP as the example operating system.)
A. Installing Windows XP and Partitioning the Hard Drive
1.
2.
Set CD-ROM drive as the first boot device under "Advanced BIOS Features" in the BIOS Setup
program. Save the changes and exit.
When partitioning your hard drive (Figure 1), make sure to leave unallocated space for Xpress
Recovery2 (10 GB or more is recommended; actual size requirements vary, depending on the
amount of data) (Figure 2).

After the operating system is installed, right-click the My Computer icon on your desktop and
select Manage (Figure 4). Go to Computer Management to check disk allocation. Xpress
Recovery2 will save the backup file to the unallocated space (black stripe along the top)(Figure 5).
Please note that if there is no enough unallocated space, Xpress Recovery2 cannot save the
backup file.
Figure 5
Figure 4
5.
If your hard drive is not properly partitioned before you install the operating system, you may
create new partitions using free space on your hard drive (Figure 6, 7). However, if Disk
Management shows the hard drive only contains the System partition without any unallocated
space, you will not be able to create new partitions or use Xpress Recovery2. If this occurs,
reinstall the operating system and re-partition your hard drive.
Figure 6
In the New Partition Wizard, you MUST select Primary
partition. This will reserve unallocated space for Xpress
Recovery2 to use.
