System Memory Configuration

This 82440EX motherboard supports 168 pin DIMM of 4MB,
8MB, 16MB, 32MB, 64MB to form a memory size between
8MB to 256MB (EDO) or 256MB (SDRAM). 82440EX
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 Unbuffered type.

CPU Installation

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

Step 1:

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

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

Hardware Installation 7

Step 2:

Install the 2 pairs of screws, which are shown in the
following drawing, onto the mainboard under the SLOT1
socket.

Two of the screws are right around the SLOT1 socket 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.

Step 3:

Retention clip is shown in the following figure:

8

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

CPU Fan in 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.

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.

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.

10

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.

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

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.)

12

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.

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.)

Turbo LED (J2 pin14, 15)

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

appears prompting you to confirm the password:

“Confirm Password:”

4. Enter exact the same password you just typed again to

confirm the password and press <Enter>.

5. Move the cursor to Save & Exit Setup to save the

password.

6. If you need to delete the password you entered before,

choose the Supervisor Password and press <Enter>. It
will delete the password that you had before.

7. Move the cursor to Save & Exit Setup to save the option

you did, otherwise the old password will still be there
when you turn on your machine next time.

8. Press <ESC> to exit to the Main Menu.

Note: If you forget or lose the password, the only way to access

the system is to clear the CMOS RAM by setting JP5.
All setup information will be lost and you need to run the
