Step 1

CPU Installation:

This mainboard supports Intel Pentium 4/Celeron Socket 478 series CPU.
Please follow the steps as follows to finish CPU installation.

Note the CPU orientation when you plug it into CPU socket.

1. Pull up the CPU socket lever to 90-degree angle.

CPU socket lever up to
90-degree angle

2. Locate Pin 1 in the socket and look for a black dot or cut edge on the CPU
upper interface. Match Pin 1 and cut edge, and insert the CPU into the

socket.

CPU Pin 1 and cut edge

3. Press down the CPU socket lever and finish CPU installation.

Note: The CPU might be
damaged if you do not match
the CPU socket Pin 1 and cut
edge well.

4. Intel Pentium 4/Celeron processors require a set of heatsink and fan to cool
down the processor. You need to purchase a heatsink and fan if they are not
bundled with your CPU. Required is that install the set and plug its cable in
the CPU fan power connector. Note that there are kinds of CPU fan connec­tors. Normally, if your mainboard supports a hardware monitoring function,
a 3-pin fan power connector can have your system detect the CPU fan's
speed. A CPU fan with a 2-pin or 4-pin fan power connector does not sup­port the detection of the CPU fan's speed, and must directly be connected to
the system's power supply unit.

- 12 -

Step 2.

Set Jumpers

The default jumper settings have been set for the common usage standard of
this mainboard. Therefore, you do not need to reset the jumpers unless you
require special adjustments as any of the following cases:

1. Clear CMOS

2. BIOS flash protect

For first-time DIY system builders, we recommend that you do not change the
default jumper settings if you are not totally familiar with the mainboard
configuration procedures. The factory-set default settings are tuned for opti­mum system performance. For the advanced users who wish to customize
their system, section 3.2 Jumper Settings will provide detailed information
on how to configure your mainboard manually.

Step 3

Install DDR SDRAM System Memory

To insert memory , insert DDR SDRAM memory module(s) in DIMM slot(s).
Note that DDR SDRAM modules are directional and will not go in the DIMM
slots unless properly oriented. After the module is fully inserted into the
DIMM slots, lift the chips of both sides of the DIMM slot to lock the module in
place.

DDR SDRAM

Step 4

Install Internal Peripherals in System Case

Before you install and connect the mainboard into your system case, we
recommend that you first assemble all the internal peripheral devices into the
computer housing, including but not limited to the hard disk drive (IDE/
HDD), floppy disk drive (FDD), CD-ROM drive, and ATX power supply unit.
This will greatly facilitate in making the connections to the mainboard de­scribed below.

To install IDE & FDD drives, follow this procedure:

1. Set the required jumpers on each device according to the instructions

provided by the manufacturer. (IDE devices, HDD, and CD-ROM, have

to set jumpers to Master or Slave mode depending on whether you install

more than one device of each kind.)

2. Connect IDE cable and FDD cable on the back-panel of the internal
peripheral devices to the corresponding headers on board. Note that

the cable should be oriented with its colored stripe (usually in red or
magenta) connected to pin#1 both on the mainboard IDE or FDD

connector and on the device as well.

3. Connect an available power cable from your system power supply unit
to the back-panel of each peripheral device. Note that the power cable

is directional and cannot fit in if not properly positioned.

- 14 -

Step 5

Mount the Mainboard on the Computer Chassis

1. You may find that there are a lot of different mounting hole positions

both on your computer chassis and on the mainboard. To choose

correct mounting holes, the key point is to keep the back-panel of the

mainboard in a close fit with your system case, as shown below.

2. After deciding on the proper mounting holes, position the studs be
tween the frame of the chassis and the mainboard. The studs are used

to fix the mainboard and to keep a certain distance between the system

chassis and the mainboard, in order to avoid any electrical shorts between

the board and the metal frame of the chassis. (If your computer case is
already equipped with mounting studs, you will need to tighten screws to
attach the mainboard.)

Note:

1. In most computer housings, you will be able to find 4 or more attachment

points to install mounting studs and then fix the mainboard. If there aren't
enough matching holes, then make sure to install at least 4 mounting
studs to ensure proper attachment of the mainboard.

2. There are two rubber pads attached on the solder-side of the mainboard. It

prevents the mainboard damaged by the improper force while installing
devices such as IDE cable, DIMM modules. You may also move the
rubber pad's position varies with your chassis design.

Step 12

First Time System Boot Up

To assure the completeness and correctness of your system installation, you
may check the above installation steps once again before you boot up your
system for the first time.

1. Insert a bootable system floppy disk (DOS 6.2x, Windows 95/98/NT, or
others) which contains FDISK and FORMAT utilities into the FDD.

2. Turn on the system power.

3. First, you must use the FDISK utility to create a primary partition of the hard
disk. You can also add an extended partition if your primary partition does
not use all of the available hard disk space. If you choose to add an ex­tended partition, you will have to create one or more logical partitions to
occupy all the space available to the extended partition. The FDISK utility
will assign a drive letter (i.e., C:, D:, E:,...) to each partition which will be
shown in the FDISK program. After FDISK procedure, reboot your system by
using the same system floppy disk.

Note : DOS 6.2x and Windows 95A can only support up to 2.1GB of

HDD partition. If you use the FDISK utility with one of the opera­ting systems mentioned above, you can only install your HDD into
partitions no larger than 2.1GB each.

4. Now, use the FORMAT utility to format all the partitions you’ve created.
When formatting the primary partition (C:), make sure to use the FORMAT

C: /S command.

Note : FORMAT C: /S can transfer all the necessary system files into the

primary partition of your hard disk. Then, your HDD will become
a bootable drive.
