2 Installing the Motherboard
This chapter describes the following:
• Installing a processor
• Preparing the motherboard for installing a boxed Pentium II processor
• Installing and removing memory
• Replacing the battery
• Installing and removing the motherboard
Before You Begin
CAUTION
Before you install this motherboard in a chassis, see Appendix B for regulatory requirements and
precautions.
• Always follow the steps in each procedure in the correct order.
• Set up a log to record information about your computer, such as model, serial numbers,
installed options, and configuration information.
• Use an antistatic wrist strap and a conductive foam pad when working on the motherboard.
WARNINGS
The procedures in this chapter assume familiarity with the general terminology associated with
personal computers and with the safety practices and regulatory compliance required for using
and modifying electronic equipment.
Disconnect the computer from its power source and from any telecommunications links,
networks, or modems before performing any of the procedures described in this chapter.
Failure to disconnect power, telecommunications links, networks, or modems before you open
the computer or perform any procedures can result in personal injury or equipment damage.
Some circuitry on the motherboard can continue to operate even though the front panel power
button is off.
CAUTION
Electrostatic discharge (ESD) can damage components. Perform the procedures described in this
chapter only at an ESD workstation. If such a station is not available, you can provide some ESD
protection by wearing an antistatic wrist strap and attaching it to a metal part of the computer
chassis.

Installing the Motherboard
Installing a Processor
To install a processor, you must:
1. Install the retention mechanism.
2. Install the processor.
3. Set the processor speed.
Detailed instructions for each of these procedures follow.
NOTE
✏
If you are installing a boxed Intel Pentium II processor, see the instructions on page 14.
Installing the Retention Mechanism
NOTE
✏
To install the retention mechanism, you need a Phillips (#2 bit) manual torque screwdriver
capable of a 6.0 in.-lb.
have a shaft longer than 2 inches.
1.0 in.-lb. (0.678 N-m ± 0.113 N-m) setting. The screwdriver also must
±
To install the retention mechanism, follow these steps:
1. Observe the precautions in “Before You Begin” (see page 11).
2. Locate Slot 1 (A in Figure 3) and the four attachment studs (B) on the motherboard.

3. To position the mechanism (C), orient it as shown in Figure 3. The tab (D) on the connector
fits into a notch in the base of the mechanism. When properly seated, the base of the
mechanism is flush with the motherboard.

AL440LX Motherboard Product Guide
CAUTION
Overtightening the captive nuts on the retention mechanism can damage the motherboard. Tighten
the captive nuts (E in Figure 3) to no more than 6.0 in.-lb.
1.0 in.-lb. (0.678 N-m ± 0.113 N-m).
±
4. Finger tighten all four captive nuts to make sure they start correctly on the threads of the
attachment studs.
5. To secure the mechanism, tighten the captive nuts with the torque screwdriver to no more than
6.0 in.-lb. ± 1.0 in.-lb. (0.678 N-m ± 0.113 N-m).
Installing the Processor
To install the processor, follow these steps:
1. Insert the processor in the retention mechanism (A in Figure 4).
2. Press down on the processor until it is firmly seated in the Slot 1 connector and the latches (B)
on the processor lock into place.

Setting the Processor Speed
After you install the processor and install the motherboard, set the processor speed by using the
Setup program. See Chapter 3 to set processor speed.
Upgrading to a Boxed Pentium® II Processor
Use the instructions in this section to prepare the motherboard for a boxed Pentium II processor
upgrade.
To prepare for a boxed Pentium II processor upgrade, you must:
1. Remove the heatsink support top bar and the installed processor.
2. Remove the heatsink support base.
3. Upgrade the processor.
Detailed instructions for each of these procedures follow.

AL440LX Motherboard Product Guide
Removing the Installed Processor
To remove the installed processor, follow these steps:
1. Observe the precautions in “Before You Begin” (see page 11).
2. Turn off all peripheral devices connected to the computer. Turn off the computer.
3. Remove the computer cover.
4. Remove the motherboard from the computer chassis. Refer to “ Installing and Removing the
Motherboard” on page 23.
5. Place the motherboard on a flat work surface and remove any components that block access to
the installed processor.
6. Remove the top bar of the heatsink support from the base as shown in Figure 6. Press in on the
latches (A) to release the top bar.

CAUTION
Pressing on the motherboard or components while removing the processor can cause damage. If
necessary, you can safely press on the motherboard’s plastic connectors to gain leverage while
removing the processor.
7. Remove the processor by pressing in on the latches (B) and pulling the processor straight up as
shown in Figure 6. Place the processor aside.

Installing the Motherboard
Removing the Heatsink Support Base
NOTE
✏
To remove the heatsink support base from the motherboard, you need a special removal tool
(MID #58982) that is available from Dexter Design (call 503-648-7000 for ordering information).
To remove the heatsink support base follow these steps:
1. With your fingers, remove the two retention pins (A) from the heatsink support base (B) as
shown in Figure 7.
