Step 1
CPU Installation:
This mainboard supports Intel® Pentium® 4 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 le er 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 le er and finish CPU installation.
Note: If you do not match the CPU socket Pin 1 and CPU cut
edge well, it may damage the CPU.

- 14 -
Step 2.
Set Jumpers
This mainboard is jumperless! The default jumper settings ha e 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 Write Protection
3. Enable/Disable IDE RAID
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 ad anced users who wish to customize
their system, section 3.2 Jumper Settings will pro ide 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
or three DIMM banks. Note that DDR 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 de ices into the
computer housing, including but not limited to the hard disk dri e (IDE/
HDD), floppy disk dri e (FDD), CD-ROM dri e, and ATX power supply unit.
This will greatly facilitate in making the connections to the mainboard de-
scribed below.
To install IDE & FDD dri es, follow this procedure:
1. Set the required jumpers on each de ice according to the instructions
pro ided by the manufacturer. (IDE de ices, HDD, and CD-ROM, ha e to
set jumpers to Master or Sla e mode depending on whether you install
more than one de ice of each kind.)
2. Connect IDE cable and FDD cable on the back-panel of the internal
peripheral de ices 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 de ice as well.
3. Connect an a ailable power cable from your system power supply unit
to the back-panel of each peripheral de ice. 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 between
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 a oid 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
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.

- 17 -
Step 6
Connect Front Panel Switches/LEDs/Speaker/USB
You can find there are se eral different cables already existing in the system
case and originating from the computers front-panel de ices (HDD LED,
Power LED, Reset Switch, PC Speaker, or USB de ices etc.) These cables
ser e to connect the front-panel switches, LEDs, and USB connectors to the
mainboards front-panel connectors group (J5 and JUSB1/3/4), as shown
below.
1. ATX Soft Power On/Off (Power ON)
2. System Management Interface Button (EPMI)
3. Green-LED/Power-LED (Green LED/Power LED)
4. HDD-LED (HDD LED)
