Chapter 2: Board Installation
Installation
You are now ready to install your motherboard. The mounting hole pattern of the Trinity i845DDR
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 which 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 the power supply.
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.
(3) Avoid touching the motherboard components, IC chips, connectors, and leads.
(4) Avoid touching memory module contacts and IC chips
(5) Place the motherboard on a grounded antistatic surface or on the antistatic bag from
which it came in.
Having reviewed the precautions above, the next step is to take the motherboard out of the
cardboard box and static bag, hold it by its edges and place it on a grounded antistatic surface,
component side up. Inspect the board for damage.
The following pages will detail for you on how to install your motherboard into your chassis, install
processor(s), memory, hard drive and floppy cables/drives and heatsinks.
NOTE DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN DAMAGED

2.0 – Board
The following is an image of the S2095 Trinity i845DDR.
The above photograph is only a representation of the actual board. Because boards tend to
be updated and go through different revisions, certain components may change and or be
repositioned. The picture above may or may not look exactly like the board you received.
The following page will detail vital components of this board.

2.1: Board Jumpers
2.2 Front Panel Connector (J20)
Your chassis will usually come with connectors to install onto the motherboard, such as HDD and
Power LEDs. The Front Panel Connector (J20) has been implemented for such purposes.

Use this connector for your chassis’ internal PC speaker. With it, the motherboard can
report to you using sequences of beeps to identify any errors that you may encounter.

Use this connector to attach a rear panel or front chassis USB ports. Front chassis USB
ports are dependant on the chassis used and the manufacturer that makes them. Check
your chassis manufacturer’s website for models that include front USB ports.

5 5
TIP: For convenience, look for a compatible chassis that also includes U SB connectors. This will
provide a convenience if you should ever need to connect devices like digital cameras or other
USB devices.

2.7 – 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 colored. Usually, the chassis
manufacturer will preinstall the support studs in ATX form factor. While this ensures general
compatibility, your TYAN product is specialized and may require you to install a few extra studs. If
you’re not sure which stud goes where, simply lay the motherboard inside the chassis, aligning the
screw holes of the motherboard to the studs inside the case. If there are any studs missing, you’ll
know right away since the motherboard will not be able to be securely installed.
Some chasses include plastic studs instead of metal ones. These ones are also usable but TYAN
recommends using metal studs with screws to make sure the motherboard does not get jarred
during shipping or lots of movement.
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.

2.8 – Installing the Memory
Before attempting to install any type of memory, make sure that the memory you have is
compatible with the motherboard as well as the processor. For example, while PC1600 DDR
SDRAM modules are compatible with all DDR based motherboards, they will not work if you are
required to run the motherboard and processor 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 website at: www.tyan.com
The following diagram shows the types of RAM modules you may encounter depending on your
board:
Here are a few key points to note before installing memory into your Trinity i845DDR:
• At least ONE DDR SDRAM module must be installed for the system to turn on and
POST (power on self test).
• 128MB, 256MB, and 512MB, 1024MB PC2100/PC1600 DDR SDRAM memory modules
are supported.
• All installed memory will be automatically detected so there is no need to set any
jumpers or settings.
• The Trinity i845DDR supports up to 2GB of memory.
