Introduction 3

There are two ways to set the CPU type and both ways are
controlled by JP18 and JP19:

1. Use SW1 (hardware): JP18/JP19 must be closed at pin 2­3 (default). Refer to the following pages (page 4~6).

2. Use BIOS (jumperless): JP18/JP19 must be closed at pin
1-2. Refer to page 28 for detail description.

System Memory Configuration

This 82440LX motherboard supports 168 pin DIMM of 4MB,
8MB, 16MB, or 32MB to form a memory size between 8MB
to 1GB (EDO) or 512MB (SDRAM). 82440LX chipsets
provide ÒTable-FreeÓ function. It means that users can
install DRAM with any configuration and in any bank, and
that is why the DRAM table is not needed but do remember
that the DRAM must be 3.3V type.

Clock Gen.

CPU Installation

Follow the following steps in order to install your Intel
Pentium II (Klamath) properly.

Step 1:

Be sure you are in contact with heat sink vendors for
attaching the heat sink on to the CPU.

Heat Sink

Intel Pentium II (Klamath)

CPU Side View

Heat Sink

Latch

Intel Pentium II (Klamath)

CPU Top View

Notice that the heat sink may be different from the drawings
shown here.

Step 2:

Install the 2 pairs of screws, which are shown in the
following drawing, onto the mainboard under the word
KLAMATH.

Two of the screws are right around the word of KLAMATH
and the other pair of screws should be inserted opposite the
first pair.

The screws should be inserted from the bottom of the
motherboard upward.

Hardware Installation 7

Step 3:

Retention clip is shown in the following figure:

Set the board according to the following diagram before
installing the retention clip.

CPU Heatsink

should be on this side.

The retention clip should be inserted so that the small
rectangle window is more toward to the right hand side of
the board.

8

If installed incorrectly, you will not be able to insert the CPU
into the retention clip and in this situation you might need
to rotate the retention clip by 180¡.

Tighten the 4 screws on the retention clip till the neck of the
screws can not be seen from the bottom of the board

Step 4:

Pull the latches up on the base of the CPU supporter and
insert it into the two holes directly to the left of the retention
clip so that the larger hole is on the bottom.

Press the base of the CPU supporter down in to the holes
and lock the latches.

Latch Latch

Side View of CPU Supporter Base

Step 5:

Flatten the two latches on the side of CPU. Insert the CPU
into the retention clip and notice that the heat sink is on the
right hand side of the board. Lock the two latches to secure
the CPU.

Hardware Installation 9

Step 6:

Insert the clip portion of the CPU supporter so that the heat
sink can sit on the top of the whole CPU supporter.

Top View of CPU Support Clip

Notice that the base and the clip of CPU Supporter may be
different from the figures shown here.

Note: 1. If the JP2 is fixed by jumperwire then the board does

not support keyboard power on function.

2. When the keyboard power on function shows any
compatible problem, choose Disabled and report the
keyboard model to the vendor/maker.

3. Keyboard power on function must be set from the
BIOS. Refer to the ÒIntegrated PeripheralsÓ section
in the Chapter 3.

IDE LED Activity Light: (J1 pin1–4)

This connector connects to the hard disk activity indicator
light on the case.

Infrared Port Module Connector (J1 pin6–10)

The system board provides a 5-pin infrared connectorÑIR1
as an optional module for wireless transmitting and
receiving. Pin 6 through 10 are Transmit, GND, Receive

(low speed), Receive (high speed), and Vcc, respectively.

J1 pin12, 13: PWR Switch

Power Switch: Toggle this pin for turnning on/off of the
power supply (for ATX power only).

SLEEP Switch (J1 pin14, 15)

Toggle this jumper forces the system to sleep and the system
wonÕt wake up until the hardware event is coming. (The
BIOS Power Management setting muse be Enabled.)

Speaker Connector (J2 pin1–4)

The speaker connector is a 4-pin connector for connecting
the system and the speaker. (See the following drawing for
jumper position.)

Reset Switch (J2 pin5, 6)

The system board has a 2-pin connector for rebooting your
computer without having to turn off your power switch.
This prolongs the life of the systemÕs power supply.

Hardware Installation 13

Power LED and Keylock Switch (J2 pin8–12)

The keylock switch is a 5-pin connector for locking the
keyboard for security purposes. (See the following drawing
for jumper position, and pin1~3 is connected to power LED
and pin 4~5 is connected to keylock switch.)

allows you to determine the number
of the CPU clocks allocated for the
RAS to accumulate/charge it before
the DRAM is refreshed.

Use the default setting. Burst
read/write requests are generated
by the CPU in four separate parts.
The 1st part provides the location
within the DRAM where the read or
write is to take place while the
remaining three parts provide the
actual data. The lower the timing
