Chapter 2: Board Installation

Installation

You are now ready to install your motherboard. The mounting hole pattern of the Tomcat K7M matches the ATX system board specifications. Your chassis should support a standard ATX motherboard form factor.

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 precautions 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 and 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) Inspect the 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

2.13 – Mounting the Motherboard

Before installing your motherboard, make sure your chassis has the necessary motherboard support studs installed. These studs are usually metal and are gold in color. Usually, the chassis manufacturer will pre-install the support studs. If you’re unsure of stud placement, simply lay the motherboard inside the chassis and align the screw holes of the motherboard to the studs inside the case. If there are any studs missing, you will know right away since the motherboard will not be able to be securely installed.

Some chassis’ include plastic studs instead of metal. Although the plastic studs are usable, TYAN recommends using metal studs with screws that will fasten the motherboard more securely in place.

Below is a chart detailing what the most common motherboard studs look like and how they should be installed.

TIP: Use metal studs if possible, as they hold the motherboard into place more securely than plastic standoffs.

http://www.TYAN.com

2.14 – 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, while PC1600 DDR modules are compatible with all DDR based motherboards, they will not work if you are required to run the motherboard and processor buses at 133MHz. For this, PC2100 DDR modules are required. Critically important is whether you’re using the recommended memory for the current board you have. For this information, please check TYAN’s web site at: www.TYAN.com

The following diagram shows the types of RAM modules you may encounter.

Use only 184-pin unbuffered non-ECC memory for S2498.

Note: The Tomcat K7M has two DIMM sockets, which supports a maximum of four banks of DDR memory (only supports 64 MB, 128 MB, 256 MB, 512MB and 1GB technologies for x8 and x16 devices.)

2.15 – Memory Installation Procedure

When you install the memory modules, make sure the module aligns properly with the memory slot. The modules are keyed to ensure that it is inserted only one way. The method of installing memory modules are detailed by the following diagrams.

Unbuffered Non-ECC = 8 Chips

Unbuffered ECC = 9 Chips

http://www.TYAN.com

Once the memory modules are firmly seated in the slot, two latches on either side will close and secure the module into the slot. Sometimes you may need to close the latches yourself.

To remove the memory module, simply push the latches outwards until the memory module pops up. Then simply remove the module.

NOTE

2.16 – Installing the Processor and Heatsink

Your brand new Tomcat K7M supports the latest processor technologies from AMD. Check TYAN’s website for latest processor support:

Due to the PCI v2.2 specifications, you MUST unplug the power connector to the motherboard before performing system hardware changes to avoid having your motherboard boot-up automatically.

http://www.TYAN.com

The following diagrams will detail how to install your processor:

The processor you choose to use may not look exactly like the one pictured above, nor will the socket look exactly the same. For example, your processor may appear to be in a different color and have different markings on it. The diagram is provided as a visual guide to help you install the processor.

1. Lift the lever on the socket until it is approximately 90 socket.

or as far back as possible to the

http://www.TYAN.com

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 sits flush with the socket.

4. Place the socket lever back down until it snaps into place.

5. Your processor is installed.

Take care when installing K7 Geode processors as they have very fragile connector pins below the processor and can bend and break if 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 the motherboard.

Because there are many different types of heatsinks available from many different manufacturers, many have their own method of installation. For the safest method of installation and information on choosing the appropriate heatsink, please refer to TYAN’s website: http://www.TYAN.com

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’re finished installing all the fans you can connect your drives (hard drives, CD-ROM drives, etc.) to your motherboard.

2.17 – Attaching Drive Cables

Attaching IDE cables to your drives is simple because they only go in one way. TYAN motherboards have two on-board IDE channels for you to use, each supporting two drives. There is a white and a black IDE connector on your motherboard. The black connector is the Primary

IDE channel and the white connector is the Secondary IDE channel.

Attaching IDE cables to the IDE connectors is illustrated below:
