Introduction
Technical Support
If a problem arises with your system, you should turn to your dealer for help
first. Your system has most likely been configured by them, and they should
have the best idea of what hardware and software your system contains.
Hence, they should be of the most assistance. Further, if you purchased your
system from a dealer near you, you can actually bring your system in to them
to have it serviced, instead of attempting to do so yourself (which can have
expensive consequences). Please refer to your dealer for specific warranty
coverage details.
Help resources:
1. See FAQ and beep codes sections of this manual.
2. See Tyan web site for FAQ, bulletins, driver updates, etc.
http://www.tyan.com
3. Contact your dealer or distributor for help BEFORE calling Tyan.
4. Check the Tyan user group: alt.comp.periphs.mainboard.tyan
Returning Merchandise for Service
During the warranty period, contact your distributor or system vendor FIRST
for any product problems. This warranty only covers normal customer use and
does not cover damages incurred during shipping or failure due to the
alteration, misuse, abuse, or improper maintenance of products.
For Resellers Only:
A receipt or copy of your invoice marked with the date of purchase is required
before any warranty service can be rendered. You can obtain service by calling
the manufacturer for a Return Merchandise Authorization (RMA) number. The
RMA number should be prominently displayed on the outside of the shipping
carton and the package should be mailed prepaid, or hand-carried to the
manufacturer. TYAN will pay to have the board shipped back to you.

Here are some precautions you should follow when installing your motherboard:
(1) Ground yourself properly before removing your motherboard
from the antistatic bag. Unplug the power from your computer
and then touch any metal part on the computer case. (Or wear a
grounded wrist strap.)
(2) Hold the motherboard by its edges and do not touch the bottom of
the board.
(3) Avoid touching motherboard components, IC chips, connectors,
and leads.
(4) Avoid touching pins of memory modules and chips.
(5) Place motherboard on a grounded antistatic surface or on the
antistatic bag.
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.
!
DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN DAMAGED!
important!
Press down on any of the socket ICs if it appears that they are not properly
seated (the board should still be on an antistatic mat). Do not touch the bottom
of the board. Remember, dont take any electronic device out of its protective
bag until you are ready to actually install it into the computer case. If you do
not ground yourself, you risk zapping the motherboard or adapter card.
Subsequent problems may not arise immediately because electrostatic discharge damage, unlike physical damage, causes the device to fail over time.

Quick References for Jumpers
In this manual, the terms closed and on are used when referring to jumpers
(or jumper pins) that are active; open and off are used when referring to
jumpers (or jumper pins) that are inactive. See the Figure 2-1 for examples of
on and off pins and jumpers.
Jumpers and pins are connected by slipping the plastic jumper connector
overtop of two adjacent jumper pins (indicated by 1-2 or 2-3). The metal rod
inside the plastic shell bridges the gap between the two pins, completing the
circuit. See Figure 2-2 for more example of pin connections.

1-G Soft Power Connector
The Soft Power Connector is part of jumper block J16. The Trinity 400 uses the
chipset for power management, including turning on and off the system. If the
Power Button Function option in the BIOS Power Management Menu is set to
On/Off (which is the default), pressing the power button once after the BIOS
has booted up will turn the system on and off. If the Power Button Function
option is set to Suspend, pressing the power button once will wake the system
or send it to Suspend mode. In this case, you cannot turn the system off
unless you shut down through the Windows operating system or you hold the
power button down for four seconds.
1-H Hardware Reset Switch Connector Installation
The Reset switch on your cases display panel provides you with the Hardware Reset function, which is the same as power on/off. The system will do a
cold start after the Reset button is pushed. (J16 pin 7 & 8)
1-I Creative Labs Audio Connectors (optional)
There are four black 4-pin
connectors onboard which are
used for various peripherals
audio signals. The digital signal
that comes in through these
connectors is directed through
the Creative Labs ES1373 PCI
sound chip, and the digital signal
is turned into an audio signal
which goes out through the
speaker. The TDA connector
(J21) is for modem audio; the
VIDEO connector is (J22); the CD
connector (J23) is for CD-ROMs.

The J7 connector is an intrusion alarm, that can be connected to the system
chassis. When active (J7 is connected to the chassis), this alarm will alert the
system administrator anytime someone opens the systems case.
http://www.tyan.com

1-K Power LED Connector
Jumper D31 is a three pin power LED header that can be used if you have a 3
pin Power LED. Otherwise refer to panel connector J16 for 2 pin LEDs. 3 pin
LEDs can still be used on J16 where pin 13 would be for the Ground pin.
CMOS RTC
The Real Time Clock (RTC) circuit, which provides the date and time for the
system is integrated into the Via Apollo Pro Plus 133A AGPset. If the external
battery for the RTC is low, it will prevent your system from POSTing, and you
will not get a display. Normally the life span of an external battery is 2 years. If
yours is running low, you will need to replace it with a new 3V lithium battery
(Sony CR2032).
Flash EEPROM
The Trinity 400 uses flash memory to store BIOS firmware. It can be updated as
new versions of the BIOS become available. You can upgrade your BIOS easily
using the flash utility (see page 60).
2. Mounting the Motherboard in the Chassis
Follow the instructions provided by the case manufacturer for proper installation guidelines. TYAN recommends that you use only one screw to hold down
the motherboard. The rest of the mounting holes should be used for the plastic
standoffs. If your case does not have a hole for a standoff, simply cut off the
bottom of the plastic standoff so that the flat portion rests on the metal. The
adapter cards and the screws holding them down will keep your board flat. The
fastening screw should not short any of the traces on the motherboard. Make
certain that you do not overtighten the screw, as it will damage the mother-
!
board and possibly break internal traces in the surrounding area. The hole you
important!
should use is located at the top-center of the board where the adapter cards
are fastened to the case.

3. Installing Memory
Since TYAN boards are manufactured with performance in mind, you should
use add-in components that match. It is highly recommended that the memory
DIMMs are installed prior to connecting the power supply. Some DIMM
modules may seem to be high quality because of name or feel but that does not
guarantee real-world usability. Some cheaper or OEM memory may have brandname components, but they may contain inferior or substandard parts which
do not meet the critical tolerances our products require. Because of this, your
memory may not work correctly in a TYAN board though it may work well in a
competitors board. This is because many of our competitors do not adhere to
the strict tolerances required for high performance. If you buy a TYAN board,
you are getting the best system available. To make installation easy and
trouble free, get high quality parts. Some brands we recommend are Advantage
Memory, Corsair Microsystems, Millenium, Kingston Memory, QesTec
Incorporated, Unigen, Micron Technology, and Crucial Technology. These
DIMMs have proven to be very stable on our boards and perform extremely
well.
warning
This motherboard operates on a 3.3 volt standby for the DIMM banks .
Because of this, you need to UNPLUG the AC power cord before installing
your DIMM memory modules. Otherwise, the motherboard may automatically
power up when the memory is inserted into the slot.
20
http://www.tyan.com
Figure 2-5*
*Note: The image above is used to illustrate a concept and may not represent the actual
image of your motherboard.
To install your DIMMs, line your module up so that the pins fit into the slot.
There is only one way that your DIMM can fit properly. Make sure that the
short row of pins is lined up with the short gap in the DIMM slot. Figure 2-5
shows how to sit the DIMM into its slot. To insert the DIMM, push down
vertically on the module with even force, as shown in the photo. Do not shove
one end in first; doing so will bend the DIMM pins.
To lock the DIMM into place, push the plastic clips on either end of the slot
onto the notches in the ends of the DIMM (see Figure 2-6 on the next page).
To remove your DIMM, simply pull the clips back, and pull up on the module.
INSTALL
Place the DIMMs in an anti-static bag as soon as you remove them to avoid
static damage.

The Trinity 400 uses a 64-bit data path from memory to CPU and can accommodate up to 768MB of SDRAM. The 168-pin DIMMs (Dual In-line Memory
Modules) must be of the 3.3V, unbuffered variety. The position of the notch in
the SDRAM key position will tell you whether or not a DIMM is unbuffered
(see the Figure 2-7 below). All installed memory will be automatically detected,
so there is no need to set any jumpers.

4. Installing the CPU and Cooling Fan
Socket 370 type Celeron processors (300 through 533MHz) and Slot 1 type Pentium
II/III can be used on the Trinity 400. Please refer to page 15 for the correct CPU
jumper settings for your CPU. Remember:
The CPU is a sensitive electronic component and it can easily be damaged
by static electricity. Do not touch the CPU pins with your fingers. You
should be able to insert the CPU into the socket with virtually zero force.
Do not press down hard on the CPU as you will bend or break pins.
Installing Socket 370 Type CPUs
Pin 1 on the CPU is denoted by a small dot on one of the corners and Pin 1 on
the ZIF socket is denoted by an angled corner.
Note: If two CPUs

are installed
important!
simultaneously,
there is a tremendous risk of
shorting out both
CPUs and the
motherboard. DO
NOT install 2CPUs
at the same time!
Figure 2-8
Push down lightly on the CPU, and lower the arm on the ZIF socket to secure
the CPU. (Figure 2-8) A squeaking noise is normal as the arm lowers. Never
force a CPU into a socket. Forcing a CPU to seat will bend the pins on the CPU
and possibly damage the motherboard. Check with your vendor or manufacturer for proper voltage selection.After the CPU is securely seated, install the
appropriate cooling device. Tyan strongly recommends a heatsink/fan combination. Consult with your case manufacturer for other cooling options.
