Installing the Motherboard
Safety Precautions
• 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
Choosing a Computer Case
There are many types of computer cases on the market. The motherboard complies with
the specifications for the Micro ATX system case. First, some features on the motherboard
are implemented by cabling connectors on the motherboard to indicators and switches on
the system case. Make sure that your case supports all the features required. Secondly,
KM400-M2 supports one or two floppy diskette drives and four enhanced IDE drives.
Make sure that your case has sufficient power and space for all 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 carries a Micro ATX form factor of 244 x 221 mm. Choose a case that
accommodates this form factor.
Installing the Motherboard in a Case
Refer to the following illustration and instructions for installing the motherboard in a case.
Most system cases have mounting brackets installed in the case, which correspond 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.

8
Installing the Motherboard
Do not over-tighten the screws as this can stress the motherboard.
Checking Jumper Settings
This section explains how to set jumpers for correct configuration of the motherboard.
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 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

necting the motherboard components. Refer to the following:
1 Connect the CPU cooling fan cable to CPUFAN1.
2 Connect the case cooling fan connector to CASFAN1.
3 Connect the case switches and indicator LEDs to the PANEL1.
If there are 3 pins in the case LED cable, connect to SJ1.

Installing the Motherboard
Hard Drive Activity LED
Connecting pins 1 and 3 to a front panel mounted LED provides visual indication 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 interface. 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 pin 5 and 7 to a momentary-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 de-
bounce circuitry. After receiving a power on/off signal, at least two seconds elapses before
the power supply recognizes another on/off signal.
Installing Hardware
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
resistors 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
motherboard 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 over-clock processors or other components to run
faster than their rated speed.

13
Installing the Motherboard
This motherboard has a Socket-462 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.
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 pin
hold noticeably missing). Align and insert the CPU
correctly.
3 Press the lever down and apply thermal
grease on top of the CPU.
4 Put the CPU Fan down on the retention
module and snap the four retention legs of
the cooling fan into place.
5 Flip the levers over to lock the heat sink in
place and connect the CPU cooling Fan
power cable to the CPUFAN connector. This
completes the installation.
CPU Installation Procedure
The following illustration shows CPU installation components.
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 installa-
tion procedures may vary with the type of CPU fan/heatsink supplied. The
form and size of fan/heatsink may also vary.
Warning: Over-clocking components can adversely affect the reliability
of the system and introduce errors into your system. Over-clocking can
permanently damage the motherboard by generating excess heat in
components that are run beyond the rated limits.

14
Installing the Motherboard
Installing Memory Modules
This motherboard accommodates two 184-pin 2.5V unbuffered Double Data Rate
(DDR)SDRAM (Synchronous Dynamic Random Access Memory) memory modules. It can
support DDR333/266/200 (PC2700/PC2100/PC1600 Double-Data-Rate DRAM) memory
modules. The total memory capacity is 2GB.
DDR SDRAM memory module table
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.
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 installed 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.
