Chapter 2: Board Installation
Installation
You are now ready to install your motherboard. The mounting hole pattern of the S2662 matches
the ATX specifications. Before continuing with installation, confirm that your chassis supports a
standard ATX motherboard.
How to install our products right…. the first time!
The first thing you should do is read this user’s manual. It contains important information that will
make configuration and setup much easier. Here are some prec autions you should take when
installing your motherboard:
(1) Ground yourself properly before removing your motherboard from the antistatic bag.
Unplug the power from your computer power supply and then touch a safely grounded
object to release static charge (i.e. power supply case). For the safest conditions, Tyan
recommends wearing a static safety wrist strap.
(2) Hold the motherboard by its edges. Do not touch the bottom of the board or flex the
board in any way.
(3) Avoid touching the motherboard components, IC chips, connectors, memory modules,
and leads.
(4) Place the motherboard on a grounded antistatic surface or on the antistatic bag that the
board was shipped in.
(5) Inspectthe board for damage.
The following pages include details on how to install your motherboard into your chassis, as well
as installing the processor, memory, disk drives and cables.
NOTE DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN DAMAGED

2.16 –Mounting the Motherboard
Before installing your motherboard, make sure your chassis has the necessary motherboard
support studs installed. These studs are usually manufacturer pre-installed, metal and are gold in
color. If you are unsure of stud placement, lay the motherboard inside the chassis and align the
studs.
NOTE YOU MUST make sure that there are no studs where there are no screw holes.

15
http://www.tyan.com
2.17 –Installing the Memory
Before attempting to install any memory, make sure that the memory you have is compatible with
the motherboard as well as the processor. For example, DDR200 and DDR266 memory
modules can be used for FSB=400MHz Intel Pentium 4 processor but only DDR266 memory
modules can be used for FSB=533MHz Intel Pentium 4 processor. For important memory
information, please check Tyan’s web site at: www.tyan.com for recommendations.
DDR200 (PC1600) DDR266(PC2100)
Pentium 4 mPGA478 FSB=400MHz Yes Yes
Pentium 4 mPGA478 FSB=533MHz No Yes
Celeron mPGA478 FSB=400MHz Yes Yes
Here are a few key points to note before installing memory modules onto your board.
•All installed memory will be automatically detected-no need to set any jumpers

Memory InstallationProcedure
When installing memory modules, make sure the modules align properly with the memory socket.
There should be a key (small indent) on your memory module that fits according to the key in the
memory socket. DDR modules and sockets have only one key, which is slightly off-center of the
module/socket.The method of installing memory modules is detailed in the following diagrams.
Once the memory modules are firmly seated in the socket, two clamps on either side will close
and secure the module into the socket. Sometimes you may need to close the clamps manually.
To remove the memory module, simply push the clamps outwards until the memory module pops
up. Then remove the module.
TIP: When installing memory, a module may require a considerabl e amount of force to seat
properly, although this is very rare. To avoid bending and damaging your motherboard, place it on
itsanti-static bag and onto a flat surface, then proceed with memory installation.
For important memory information, please check Tyan’s web site at www.tyan.com for
recommendations.
NOTE YOU MUST unplug the power supply before performing system hardware
changes in order to avoid damaging the board or expansion device.

2.18 –Installing theProcessor and Heatsink
The S2662 supports the mPGA478 Pentium 4 processors technologies from Intel. For important
CPU information, please check Tyan’s web site at: www.tyan.com .
The following diagrams will detail how toinstallyour processor:
The processors you choose to use may not look exactly like the one pictured above, nor will the
socket look exactly the same. The diagram is a visual guide to help you install processors.
1. Lift the lever on the socket as far back as possible to the socket.
2. Align the processor with the socket. There are keys underneath the processor just like
on memory modules to ensure that they insert the correct way.
3. Seat the processor firmly into the socket by gently pressing down until the processor
sitsflush with the socket.
4. Placethe socket lever back downuntil it snapsinto place.
5. Yourprocessor isinstalled.
Take care when installing the processor as it has fragile connector pins that can bend and
breakif inserted improperly.
Heatsink Installation
After you are done installing the processor, you should proceed to installing the heatsink. The
heatsink will ensure that the processor does not overheat, and will continue to operate at
maximum performance. An overheated processor is also dangerous to the long-term reliability of
themotherboard.

19
http://www.tyan.com
The following diagram will illustrate how to install the most common heatsinks:
Install the mounting bracket onto the motherboard by
aligning the bracket with the four holes around the
processor socket. Once the bracket is aligned, press
down on the four white pegs on the bracket until they
insert securely, locking the bracket onto the
motherboard. Then proceed to installing the heatsink.
Instructions on how to install heatsinks should be
provided with the heatsink itself.
First, use thermal compound (also called heatsink
compound or thermal grease) and apply a small amount
on to the processor’s core –the small shiny square in
the center of the processor.
Then, at an angle, clip one side of the heatsink onto the
socket and then lay the heatsink flat onto the processor.
Then clip the other end of the heatsink down by using a
flathead screwdriver.
Some heatsinks have a small clip on the inside of one of
the clips which you can insert a small flathead screw
driver into to secure the heatsink.
Because one side of the socket is raised (and usually
has “SOCKET” imprinted into it) heatsinks have an
indent on one side to secure flush with the raised side of
thesocket.
Be sure to carefully observe which side your heatsink is
seated before securing it down to avoid damaging the
processor,the heatsink or both.
Finishing Installing the Heatsink
After you finish installing the heatsink onto the processor and socket, attach the end wire of the
fan (which should already be attached to the heatsink) to the motherboard. The following diagram
illustrates how to connect fans onto the motherboard.
After you have finished installing all the fans you can connect your drives (hard drives, CD-ROM
drives, etc.) to your motherboard.

20
http://www.tyan.com
2.19 –Installing Add-In Cards
Before installing add-in cards, it is helpful to know if they are fully compatible with your
motherboard. For this reason, we have provided the diagrams below showing the most common
slots that may appear on your motherboard. Not all of the slots shown will necessarily appear on
your motherboard. However, there will be combinations of what you see here.
Find the appropriate slot for your add-in card and insert the card firmly. Do not force any add-in
cards (or anything else) into any slots if they will not seat in place.
NOTE YOU MUST unplug the power supply before performing system hardware
changes in order to avoid damaging the board or expansion device.
Before Continuing onto section Connecting External Devices, make sure everything is properly
connected. Things like jumpers and case wiring are the most common causes of troubleshooting
frustrations, both for the end-userandforanycompanydoingtechnicalsupport.
