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.
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.
3. Press down the CPU socket lever and finish CPU installation.
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 connec-
tors. Normally, if your mainboard supports a hardware monitoring function,
a 3-pin fan power connector can have your system detect the CPU fan's spe-
ed. 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.
CPU socket lever up to
90-degree angle
CPU Pin 1 and cut edge
Note:The CPU might be damaged if you
do not match the CPU socket Pin 1
and cut edge well.

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
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 con-
figuration procedures. The factory-set default settings are tuned for optimum
system performance. For the advanced users who wish to customize their sys-
tem, section 3.2 Jumper Settings will provide detailed information on how to
configure your mainboard manually.
Before clearing CMOS, please make sure to unplug AC cable connector.
Step 3
Install DDR SDRAM System Memory
To install 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 clips of both sides of the DIMM slot to lock the module in place.
Do not remove memory modules while DIMM LED is on. It might cause short
or other unexpected damages due to the 2.5V standby voltage.
Remove memory modules only when AC Power cord is disconnected.

Step 4
Install Internal Peripherals in System Case
Before you install and connect the mainboard into your system case, we rec-
ommend that you first assemble all the internal peripheral devices into the com-
puter 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 pro-
vided 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 periph-
eral devices to the corresponding slots 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.

- 15 -
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 between the
frame of the chassis and the mainboard. The studs are used to fix the main-
board and to keep a certain distance between the system's 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 :In most computer housings, you will be able to find 4 or more
attachment points to install mounting studs and then fix the main-
board. If there aren't enough matching holes, then make sure to
install at least 4 mounting studs to ensure proper attachment of
the mainboard.

- 16 -
Step 6
Connect Front-Panel Switches/LEDs/Speaker connectors
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 or PC Speaker etc.) These cables serve to connect the front-
panel switches and LEDs to the mainboard's front-panel connectors group
(JP 2), as shown below.
1. ATX Power On/Off Switch Connector (PWON)
2. Green LED/Power LED Connector (GLED/PLED)
