1-3 Installing the CPU and CPU Cooler

Read the following guidelines before you begin to install the CPU:

•Make sure that the motherboard supports the CPU.

(Go to GIGABYTE's website for the latest CPU support list.)

•Always turn off the computer and unplug the power cord from the power outlet before

installing the CPU to prevent hardware damage.

•Locate the pin one of the CPU. The CPU cannot be inserted if oriented incorrectly. (Or you

may locate the notches on both sides of the CPU and alignment keys on the CPU socket.)

•Apply an even and thin layer of thermal grease on the surface of the CPU.

•Do not turn on the computer if the CPU cooler is not installed, otherwise overheating and

damage of the CPU may occur.

•Set the CPU host frequency in accordance with the CPU specifications. It is not recom-

mended that the system bus frequency be set beyond hardware specifications since it

does not meet the standard requirements for the peripherals. If you wish to set the fre-

quency beyond the standard specifications, please do so according to your hardware

specifications including the CPU, graphics card, memory, hard drive, etc.

Step 3:

Place the cooler atop the CPU, aligning the

four push pins through the pin holes on the

motherboard. Push down on the push pins

diagonally.

Step 4:

You should hear a "click" when pushing down each

push pin. Check that the Male and Female push pins

are joined closely. (Refer to your CPU cooler instal-

lation manual for instructions on installing the cooler.)

Use extreme care when removing the CPU cooler because the thermal grease/tape between

the CPU cooler and CPU may adhere to the CPU. Inadequately removing the CPU cooler may

damage the CPU.

Step 5:

After the installation, check the back of the

motherboard. If the push pin is inserted as the

picture above, the installation is complete.

Step 6:

Finally, attach the power connector of the CPU

cooler to the CPU fan header (CPU_FAN) on

the motherboard.

1-4 Installing the Memory

Read the following guidelines before you begin to install the memory:

•Make sure that the motherboard supports the memory. It is recommended that memory of

the same capacity, brand, speed, and chips be used.

(Go to GIGABYTE's website for the latest memory support list.)

•Always turn off the computer and unplug the power cord from the power outlet before

installing the memory to prevent hardware damage.

•Memory modules have a foolproof design. A memory module can be installed in only one

direction. If you are unable to insert the memory, switch the direction.

Due to chipset limitation, read the following guidelines before installing the memory in Dual Channel mode.

1. Dual Channel mode cannot be enabled if only one DDR2 memory module is installed.

2. When enabling Dual Channel mode with two or four memory modules, it is recommended that

memory of the same capacity, brand, speed, and chips be used and installed in the same

colored DDR2 sockets for optimum performance.

When memory modules of different capacity and chips are installed, a message which says

memory is operating in Flex Memory Mode will appear during the POST. Intel® Flex Memory

Technology offers greater flexibility to upgrade by allowing different memory sizes to be

populated and remain in Dual Channel mode/performance.

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 (500W 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.

- 33 - BIOS Setup

Chapter 2 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 introduc-

tions of the battery/clearing CMOS jumper in Chapter 1 for how to clear the CMOS values.)

4-1 Xpress Recovery2

"*" 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.

Chapter 4 Unique Features

Xpress Recovery2 is a utility that allows you to quickly compress and

back up your system data and perform restoration of it. Supporting

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 require-

ments 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® platform

•At least 64 MB of system memory

•VESA compatible graphics card

•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.

3. Select a file system (for example, NTFS) and begin the installation of the operating system (Figure 3).

Installation and Configuration

(The following procedure uses Windows XP as the example operating system.)

A. Installing Windows XP and Partitioning the Hard Drive

1. Set CD-ROM drive as the first boot device under "Advanced BIOS Features" in the BIOS Setup

program. Save the changes and exit.

2. 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).

Figure 2

Unique Features- 65 -

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 7

4. 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

In the New Partition Wizard, you MUST select Primary

partition. This will reserve unallocated space for Xpress

Recovery2 to use.

C. Using the Backup Function in Xpress Recovery2

1. Select BACKUP to start backing up your hard drive data (Figure 10).

2. Xpress Recovery2 will then begin to search the first physical hard drive as the target drive and

detect whether this hard drive contains the Windows operating system. When the Windows

operating system is detected, Xpress Recovery2 will begin the backup process (Figure 11).

Figure 10 Figure 11

2. After you use the backup function in Xpress Recovery2 for the first time, Xpress Recovery2 will

stay permanent in your hard drive. If you wish to enter Xpress Recovery2 later, simply press

<F9> during the POST (Figure 9).

(Figure 8), press any key to enter Xpress Recovery2.

Xpress Recovery2 will automatically create a

new partition to store the backup image file.

3. When finished, go to Disk Management to check disk allocation.
