Chapter 2: Board Installation

Installation

You are now ready to install your motherboard. The mounting hole pattern of the Tomcat i845GV
matches the FlexATX system board specifications. Your chassis should support a standard
FlexATX 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

2.3 – Fan Connectors (FAN1, FAN2, FAN3)

Use these headers to connect cooling fans, both chassis and
processor fans, to your motherboard. Cooling fans help keep the
system more stable and operating reliably for its product life.

2.4 – CMOS Reset (JP1)

Connect pins 1 and 2 together to reset the CMOS settings in case an incorrect
setting causes system instability or you have forgotten your system/setup
password or have just flashed your BIOS.

Power off the system and disconnect the power supply.

- Close pins 2 and 3 on JP1

Clear CMOS

- Wait about 5 seconds

- Close pins 1 and 2 on JP1

- Reconnect the power supply and power on the system

2.5 – Front Panel Connector (J9)

Your chassis will usually come with connectors to install onto the motherboard, such as HDD and
Power LEDs. The Front Panel Connector has been implemented for such purposes.

2.9 – 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.

2.10 – 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 S2198.

Note: The Tomcat i845GV has two DIMM sockets, which supports a maximum of four banks of
DDR memory (only supports 64 Mb, 128 Mb, 256 Mb, and 512 Mb technologies for
x8 and x16 devices.)

.

Unbuffered
Non-ECC
= 8 Chips

Unbuffered
ECC
= 9 Chips

2.11 – 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.

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

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.
