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. CPU Frequency

3. BIOS Flash Protection

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 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.

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 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 there are a lot of mounting holes on your computer chassis
and mainboard. To match the holes on both properly, the key point is to
make the back panel of the mainboard in a close fit with your system case,
as shown below.

2. Position the studs between the chassis and the mainboard. The studs are
used to fix the mainboard and to keep a certain distance between the
them, for avoiding any electrical shorts in-between.

(If your computer case is already equipped with mounting studs, you need
to tighten the screws to attach the mainboard.)

Note: In most computer housings, you can find 4 or more holes to place

studs for fixing the mainboard. If there aren't enough matching holes,
screw at least 4 studs to ensure the proper attachment of the main­board.

ATX Power Supply Connectors (ATX1/ATX2)

This motherboard uses 20-pin ATX power header (ATX1), and comes with
the other one header (ATX2). Please make sure you plug each in the right
direction. It is essential to have these two power supply connectors plugged
or your system won't boot up.

ATX1 ATX2

ATX1

A traditional ATX system remains in the power-off stage when AC power re­sumes from power failure. However, it is inconvenient for a network server or
workstation if there is not an UPS to execute power-on. Thus, this motherboard
supports an AC Power Auto Recovery function to solve this problem. You may
enable the function, "PWRON After PWR-Fail," in the sub-menu of "Power
Management Setup" within the BIOS setup program.

Note 1: The ATX power connector is directional and will not go in

unless the guides match perfectly, making sure that pin#1 is
properly positioned.

ATX2

Note 2: Make sure the latch of the ATX power connector clicks into

place to ensure a solid attachment.

Note 3: Your ATX power supply must be supplied to ACPI+5V stand-

by power and at least 720mA compatible.

Note 4: Make sure your power supply have enough power for higher
