This symbol indicates a CAUTION or WARNING.
It identifies operations or situations that may be
harmful or dangerous to you or your equipment.
For your safety and to protect your equipment,
read and observe all cautions and warnings.
Explanation of symbols used in this guide:
This symbol indicates a NOTE. It identifies items
of special interest that pertain to the section or
procedure you are reading. Notes typically clarify
or expand the material in the text.

Step 1—Check your computer's BIOS.
Caution: Failure to update an incompatible BIOS will
cause your computer to lock up after installation.
The system control program (BIOS) in some computers doesn't support the
higher speed of the Pentium OverDrive processor with MMX technology.
You must update an incompatible BIOS before installing the processor.
Failure to update your incompatible BIOS will cause your computer to lock
up after installation. This lock-up may occur every time you start your
computer or only after you install new hardware such as graphics or audio
cards.
Follow these steps to determine whether your computer's BIOS must be
updated.
1. Insert the OverDrive Processor Diagnostic diskette in drive A.
2. Choose File (for Windows* 3.1 or Windows NT*)
or Start (Windows 95 or Windows NT 4.0).
3. Choose Run.
4. Type a:\diag, click OK, then choose Run Diagnostics from the menu.
If your computer's BIOS is incompatible with the Pentium OverDrive
processor with MMX technology, you must update the BIOS before
installing the Pentium OverDrive processor with MMX technology (see
"BIOS update needed" on page 17).
A successful result indicates that the likelihood of encountering a
problem due to a BIOS incompatibility is low. Please continue the
installation with Step 2. This diagnostic is limited to certain BIOS
tests only; it does not test for other possible incompatibilities
between the Pentium OverDrive processor with MMX technology and a
particular PC hardware configuration.
If you experience problems after installing the Pentium OverDrive
processor with MMX technology, contact Intel customer support for more
information. (See "Getting Help" on page 21.)
First check your computer owner's manual to see if it has a section on
installing computer upgrade hardware such as the Pentium OverDrive
processor with MMX technology. If it does, follow the owner's manual
procedure. Otherwise, use this manual.

Step3—Unplugcomputerandremovecover.
Step 2—Ground yourself.
To prevent damaging the Pentium OverDrive processor with MMX
technology and your computer with a static discharge, ground yourself by
touching the metal back or side panel of your computer’s system unit.
Warning: Danger to equipment! The Pentium
OverDrive processor with MMX technology can be
damaged by static discharge. Before handling the
Pentium OverDrive processor with MMX technology,
be sure to ground yourself by touching the metal on
your computer. Limiting your movements during
installation reduces static electricity.
Warning: Don't burn yourself! Many components can
become hot enough to cause mild skin burns. Wait at
least 15 minutes after turning off the power before
handling any parts.
Turn off the computer and any attached equipment (such as a monitor or
printer), unplug the power cord, and remove the cover.

Step 4—Find the computer's Pentium
processor.
Find the Pentium processor in the computer. The Pentium processor in
most computers looks like the following:
Some computers have a power cable attached to the Pentium processor's fan
or have a passive heat sink (which may be attached with a clip) on top of
the Pentium processor .

Your computer's owner's manual may show the location of the processor. If
you can't locate your computer's original processor, contact your dealer or
your computer manufacturer for assistance.
Some computers have an empty second socket next to
the processor. For more information on the installation
process for these computers, see page 15.

After locating the processor, examine the socket to determine the socket
type. Most Pentium processor-based computers use a socket with a handle
that locks and unlocks, called a zero insertion force (ZIF) socket.
If the socket in your computer doesn't have a handle,
Intel strongly recommends that you have a qualified
professional install the Pentium OverDrive processor
with MMX technology rather than installing it yourself.

(with handle)
Some computers use a socket without a handle, called a low insertion force
(LIF) socket.
• If your computer has either a power cable attached to the Pentium
processor's heat sink or a heat sink attached with a clip, go to step 5.
• If your computer doesn't have a power cable attached to the heat sink
and doesn't have a heat sink attached with a clip, skip step 5 and go to
step 6.

The heat sink on your computer's original processor is either clipped to the
socket or fastened directly to the top of the processor. If the heat sink is
fastened directly to the processor without a clip and doesn't have a fan
cable, go to step 6 now.
You do not need the fan, fan cable, or clip to install the
Pentium OverDrive processor with MMX technology.
After removing these parts, store them with your
original processor.

Unplugthefanpowercable
Some computers have a power cable attached to the fan. Carefully unplug
the fan power cable from the power source.
After unplugging the fan power cable, carefully fold the
power source cable out of the way so it doesn't touch
any computer components.

Removingtheheatsinkclip
If the heat sink is clipped to the socket, remove the clip by pressing down
and unfastening it from the tab on the socket. Be sure to hold your hand
over the clip while unfastening it to prevent it from flying loose.

Typical passive heat sink clip
Some heat sinks clamp tightly over the socket tab and require a tool such as
a screwdriver to loosen the clip enough to slide over the tab. Carefully
insert the tool between the heat sink and the socket, just above the socket
tab, and gently pry outward to allow the heat sink to slip over the tab. You
should then be able to completely release the heat sink from all the other
socket tabs.

Push the handle slightly sideways to slide it over the lever lock tab, then
move the handle to a 90-degree, upright position. Be sure the socket is
completely open. Don't use excessive force. Your computer’s motherboard
should not bend or flex while you are opening the socket. Once the socket
is open, remove the processor.
Be sure the socket is
completely open.

Some manufacturers use thermal grease to attach the
heat sink to the processor. Thermal grease is a
conductive material and can damage your computer if it
gets on socket pin holes, processor pins, or other
components. Avoid getting thermal grease residue on
your hands or the computer when you remove the heat
sink from the processor.
Save the original processor in case you need it later. Store it in a safe place,
such as in the box that the Pentium OverDrive processor with MMX
technology came in.

Step 7—Insert the Pentium OverDrive
processor with MMX technology into the
socket.
Correctly orienting your Pentium OverDrive processor with MMX
technology in the socket is crucial to the success of your installation. The
Pentium OverDrive processor with MMX technology fits in the socket only
one way.
Incorrectly aligning your Pentium OverDrive processor
with MMX technology can damage the processor and
your computer.
Orient the notch on one corner of the OverDrive processor with MMX
technology to the notch on one corner of the socket. Place the Pentium
OverDrive processor with MMX technology on the socket and align the
pins with the pin holes.

Once the pins and pin holes are properly aligned, gently insert the processor
into the socket. Don't use force to insert the processor in the socket.
