There are many types of computer cases on the market. The motherboard
complies with the specifications for the Micro-ATX system case. Some fea-
tures on the motherboard are implemented by cabling connectors on the
motherboard to indicators and switches on the system case. Ensure that your
case supports all the features required. The motherboard can support one or
two floppy diskette drives and four enhanced IDE drives. Ensure that your
case has sufficient power and space for all the drives that you intend to install.
Most cases have a choice of I/O templates in the rear panel. Make sure that
the I/O template in the case matches the I/O ports installed on the rear edge
of the motherboard.
This motherboard has a Micro-ATX form factor of 244 mm x 200 mm. Choose
a case that accommodates this form factor.

Follow these safety precautions when installing the motherboard:
• Wear a grounding strap attached to a grounded device to avoid
damage from static electricity.
• Discharge static electricity by touching the metal case of a safely
grounded object before working on the motherboard.
• Leave components in the static-proof bags they came in.
• Hold all circuit boards by the edges. Do not bend circuit boards.

Refer to the following illustration and instructions for installing the mother-
board in a case:
This illustration shows an ex-
ample of a motherboard being
installed in a tower-type case:
Note: Do not overtighten
the screws as this
can stress the moth-
erboard.
Most system cases have
mounting brackets installed in
the case, which correspond to
the holes in the motherboard.
Place the motherboard over
the mounting brackets and
secure the motherboard onto
the mounting brackets with
screws.
Ensure that your case has an I/O template that supports the I/O ports and
expansion slots on your motherboard.

This section explains how to set jumpers for correct configuration of the moth-
erboard.
Setting Jumpers
Use the motherboard jumpers to set system configuration options. Jumpers
with more than one pin are numbered. When setting the jumpers, ensure that
the jumper caps are placed on the correct pins.
The illustrations below show a 2-pin jumper.
When the jumper cap is placed on both pins,
the jumper is SHORT. If you remove the
jumper cap, or place the jumper cap on just
one pin, the jumper is OPEN.
This illustration shows a 3-pin
jumper. Pins 1 and 2 are SHORT.

Front Panel Connector
The front panel connector (PANEL1) provides a standard set of switch and
LED connectors commonly found on ATX or micro-ATX cases. Refer to the
table below for information:
Pin Function Pin Function
1 Hard disk LED
(positive) 2 MSG LED [dual color or single color (+)]
3 Hard disk active LED
(negative) 4 MSG LED [dual color or single color (-)]
5 Reset Switch 6 Power Switch
7 Reset Switch 8 Power Switch
9 Reserved 10 No pin
Hard Drive Activity LED
Connecting pins 1 and 3 to a front panel mounted LED provides visual indica-
tion that data is being read from or written to the hard drive. For the LED to
function properly, an IDE drive should be connected to the onboard IDE inter-
face. The LED will also show activity for devices connected to the SCSI (hard
drive activity LED) connector.
Power / Sleep / Message Waiting LED
Connecting pins 2 and 4 to a single- or dual-color, front panel mounted LED
provides power on/off, sleep, and message waiting indication.
Reset Switch
Supporting the reset function requires connecting pins 5 and 7 to a momen-
tary-contact switch that is normally open. When the switch is closed, the board
resets and runs POST.
Power Switch
Supporting the power on/off function requires connecting pins 6 and 8 to a
momentary-contact switch that is normally open. The switch should maintain
contact for at least 50 ms to signal the power supply to switch on or off. The
time requirement is due to internal debounce circuitry. After receiving a power
on/off signal, at least two seconds elapses before the power supply recog-
nizes another on/off signal.

Installing the Processor
Caution: When installing a CPU heatsink and cooling fan make sure that
you DO NOT scratch the motherboard or any of the surface-mount resis-
tors with the clip of the cooling fan. If the clip of the cooling fan scrapes
across the motherboard, you may cause serious damage to the mother-
board or its components.
On most motherboards, there are small surface-mount resistors near the
processor socket, which may be damaged if the cooling fan is carelessly
installed.
Avoid using cooling fans with sharp edges on the fan casing and the
clips. Also, install the cooling fan in a well-lit work area so that you can
clearly see the motherboard and processor socket.
Before installing the Processor
This motherboard automatically determines the CPU clock frequency and
system bus frequency for the processor. You may be able to change these
settings by making changes to jumpers on the motherboard, or changing the
settings in the system Setup Utility. We strongly recommend that you do not
overclock processors or other components to run faster than their rated
speed.
Warning: Overclocking components can adversely affect the reliability of
the system and introduce errors into your system. Overclocking can per-
manently damage the motherboard by generating excess heat in
components that are run beyond the rated limits.
This motherboard has an mPGA478 socket. When choosing a processor,
consider the performance requirements of the system. Performance is based
on the processor design, the clock speed and system bus frequency of the
processor, and the quantity of internal cache memory and external cache
memory.

CPU Installation Procedure
The following illustration shows CPU installation components:
Note: The pin-1 corner is marked with an arrow
Follow these instructions to install the Retention Module and CPU:
1. Install your CPU. Pull up
the lever away from the
socket and lift up to 90-
degree angle.
2. Locate the CPU cut
edge (the corner with the
pinhole noticeably miss-
ing). Align and insert the
CPU correctly.

14
3. Press the lever down.
4. Apply thermal grease on top of the CPU.
5. Put the CPU Fan down
on the retention module
and snap the four reten-
tion legs of the cooling
fan into place.
6. Flip the levers over to lock the heat sink in place.
7. Connect the CPU Cool-
ing Fan power cable to
the CPUFAN1 connec-
tor. This completes the
installation.
Notes: To achieve better airflow rates and heat dissipation, we suggest that you
use a high quality fan with 4800 rpm at least.
CPU fan and heatsink installation procedures may vary with the type of CPU
fan/heatsink supplied. The form and size of fan/heatsink may also vary.

15
Installing Memory Modules
This motherboard accommodates two 184-pin 2.5V unbuffered Double Data
Rate (DDR) SDRAM memory modules. The memory chips must be standard
or registered SDRAM (Synchronous Dynamic Random Access Memory).
When you installed DDR333 memory modules, the memory bus can run up to
166 MHz. If you have DDR266, this can operate over a 133 MHz. For
DDR200, it can only run up to 100 MHz.
You must install at least one module in any of the two slots. Each module can
be installed with 32 MB to 1 GB of memory; total memory capacity is 2 GB.
Do not remove any memory module from its antistatic packaging until
you are ready to install it on the motherboard. Handle the modules only
by their edges. Do not touch the components or metal parts. Always
wear a grounding strap when you handle the modules.
Installation Procedure
Refer to the following to install the memory modules.
1. This motherboard supports unbuffered DDR SDRAM only. Do not attempt
to insert any other type of DDR SDRAM into the slots.
2. Push the latches on each side of the DIMM slot down.
3. Align the memory module with
the slot. The DIMM slots are
keyed with notches and the
DIMMs are keyed with cutouts
so that they can only be in-
stalled correctly.
4. Check that the cutouts on the
DIMM module edge connector
match the notches in the
DIMM slot.
5. Install the DIMM module into
the slot and press it firmly
down until it seats correctly.
The slot latches are levered
upwards and latch on to the
edges of the DIMM.
6. Install any remaining DIMM modules.

16
Installing a Hard Disk Drive/CD-ROM
This section describes how to install IDE devices such as a hard disk drive
and a CD-ROM drive.
Your motherboard has a primary and secondary IDE channel interface (IDE1 and
IDE2). An IDE ribbon cable supporting two IDE devices is bundled with the moth-
erboard.
If you want to install more than two IDE devices, get a second IDE cable and
you can add two more devices to the secondary IDE channel.
You must orient the cable connector so that the pin 1 (color) edge of the
cable corresponds to the pin 1 of the I/O port connector.
IDE1: Primary IDE Connector
The first hard drive should always be connected to IDE1.
IDE2: Secondary IDE
The second drive on this controller must be set to slave mode. The configura-
tion is the same as IDE1.
