Step 1
CPU Installation:
This mainboard supports Intel Pentium 4/Celeron , Socket 478 series CPU.
Please follow the step as below to finish CPU installation.
Be careful of CPU orientation when you plug it into CPU socket.
1. Pull up the CPU socket lever and 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, then insert the CPU
into the socket.
CPU pin 1 and cut edge
CPU socket lever up to
90 degree

- 13 -
3. Press down the CPU socket lever and finish CPU installation.
Note:Note:
Note:Note:
Note: If you do not match the CPU socket Pin 1 and CPU cut edge
well, it may damage the CPU.
4. The Intel Pentium 4 /Celeron processor requires a set of heatsink/fan to en
sure proper cooling of the processor. If heatsink/fan have not been already
bundled with your CPU, you must purchase the heatsink/fan separately and
have it installed. Plug the cable through the heatsink/fan in the CPU fan
power connector located nearby. Note that there are several types of CPU
fan connectors. Normally, if your mainboard supports the hard ware moni
toring function, a 3-pin fan power connector should allow your system to
detect the CPU fan's speed. The CPU fan can also run with a 2-pin fan
power connector, however, detection of CPU fan's speed is not supported.
Another type of CPU fan may feature a large 4-pin fan power connector,
which does not support CPU fan's speed detection and must be directly
connected to the system's power supply unit.

- 14 -
Step 2.
Set Jumpers
This mainboard is jumperless! 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. Boot ROM protection
3. Enable/Disable LAN
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 opti-
mum system performance. For the advanced users who wish to customize
their system, section 3.2 Jumper Settings3.2 Jumper Settings
3.2 Jumper Settings3.2 Jumper Settings
3.2 Jumper Settings will provide detailed information
on how to configure your mainboard manually.
Step 3
Install DDR SDRAM System Memory
To install memory, insert DDR-SDRAM memory module(s) in any one or two
DIMM banks. Note that SDRAM modules are directional and will not go in
the DIMM banks if they are not properly oriented. After the module is fully
inserted into the DIMM bank, lift the clips of both sides of the DIMM bank to
lock the module in place.

- 15 -
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 de-
scribed 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 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.

- 16 -
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:Note:
Note:Note:
Note: 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 arent enough matching holes, then make sure
to install at least 4 mounting studs to ensure proper attachment of
the mainboard.

- 17 -
Step 6
Connect Front Panel Switches/LEDs/Speaker/USB
You can find there are several different cables already existing in the system
case and originating from the computer's front-panel devices (HDD LED,
Power LED, Reset Switch, PC Speaker, or USB devices etc.) These cables
serve to connect the front-panel switches, LEDs, and USB connectors to the
mainboard's front-panel connectors group (JP11), as shown below.
