Introduction
Overview
The S1598 Trinity ATX is a quality, high performance mainboard designed for
Socket 7 microprocessors. This mainboard utilizes the VIA MVP3 100MHz
AGPset and host bus speeds of 66MHz to 100MHz. For CPU speed support,
please refer to the CPU Compatibility Chart in T yan’ s website
(http://www .tyan.com/support/html/socket_7_compatibility.html). The Trinity
ATX also has 100MHz Front Side Bus support, which allows you to take full
advantage of 100MHz SDRAM memory modules.
The S1598 mainboard, with built-in AGP slot, provides high performance
capabilities that are ideal for a wide range of demanding applications such as
CAD, CAM, CAE, desktop publishing, 3D animation, and video production.
This system board achieves high reliability with numerous features and yet is
small enough to be supported in an ATX form factor. Some of the features
included are onboard dual channel PCI PIO, Bus Master IDE and UltraDMA/
66, onboard floppy controller, and onboard high speed I/O. Flexibility and
expandability have been designed into the Trinity ATX. With I/O and drive
controller support built onboard, the one AGP slot, five PCI and two ISA slots
(one shared, seven usable) are free for numerous add-on expansion cards.

T echnical 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 to 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).

Precautions
INST ALL
What’s the first thing I should do?
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 follow when installing your motherboard:
(1) Ground yourself properly before removing your motherboard
from the antistatic bag. Unplug the power from your computer
S1598 Trinity A TX

Chapter 2
Board Installation
and then touch any metal part on the computer case. (Or wear a

important!
grounded wrist strap.)
(2) Hold the motherboard by its edges and do not touch the bottom of
the board.
(3) A void touching motherboard components, IC chips, connectors,
and leads.
(4) A void 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 APPL Y POWER T O THE BOARD IF IT HAS BEEN DAMAGED!
warning
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, don’t 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.
*Power Supply Requirement: If you use an A TX Power Supply , it should be
2.01 compliant. Standby curr ent must be 750mA or higher (SB5V = 0.75A)
Installation Steps
You are now ready to install your mainboard. The mounting hole pattern of the
S1598 matches the ATX system board specifications. Your chassis should
have standard ATX mainboard form factor mounting holes and an ATX power
supply.

What is a Jumper?
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. The square pin in the diagram is Pin 1.
Jumpers and pins are connected by slipping the blue 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 examples of pin connections.
The tables and maps on the following pages will help you set the jumpers for CPU
speed, Infrared, and external connector pin assignments, among others. The
miniature motherboard maps will help you locate the jumpers on your board. A

ACPI Bi-Color LED Connector (J5)
This connector provides a bi-color (green / yellow) LED for your computer
chassis. When the computer system is On, the Green LED will light up. If the
system is on stand-by mode, the Yellow LED will light up. Whenever there is
an incoming message, the LED will flash on and off.
Soft Power Connector
The Soft Power Connector is located on pins 6 and 8 of jumper block J3.
Pressing the Soft Power Button will turn the sytem on and off. Holding this
button for more than four seconds (when the system is on) will power down
the system. Pressing it again will reboot the system.
Speaker Connector Installation
The Trinity ATX provides a 4-pin header to connect the speaker. The speaker
is connected to jumper block J4.
CMOS RTC
The VIA MVP3 AGPset includes a Real Time Clock (R TC) circuit, which
provides the date and time for the system. If the external battery for the RTC is
low , you will lose your BIOS settings. 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).
USB
There are two ATX Universal Serial Bus ports on the back of the board. The
board also has an additional USB header (USB2, USB3) on the edge of the
board near the third PCI slot. This header can be used to connect a USB port
on the front of the chassis.
Flash EEPROM
The Trinity ATX uses flash memory to store BIOS programs. It can be easily
updated if necessary using the flash utility (see page 57). Tyan does not
recommend flashing the BIOS unnecessarily . Check the Tyan web site for the
latest BIOS revision.
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
http://www.tyan.com
16
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 motherboard and possibly break internal traces in the surrounding area. The hole you
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. 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 brand-name 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 competitor’s
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 Corsair Microsystems,
Kingston Memory, and QesTec Incorporated. These DIMMs have proven to
be very stable on our boards and perform extremely well. For a list of recommended memory vendors, please visit T yan’s website at www .tyan.com (go to
the Memory Support area in the Support section).
This table lists some
of the possible memory
configurations. Not all
possible configurations
are listed.
Note: This board does NOT

Figure 2-3
*The image above is used to illustrate a concept and may not represent the actual image of
your motherboard.
T o 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 2-3
above 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.
T o 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 2-4 on the next page).
T o remove your DIMM, simply pull the clips back, and pull up on the module.
Place the DIMMs in an anti-static bag as soon as you remove them to avoid
static damage.
The Trinity 100AT uses a 64-bit data path from memory to CPU and can
accommodate up to 384MB 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 Figure 2-5 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 7 processors (see Specifications
on page 5) can be used on the Trinity
A TX. Please refer to page 14 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.
• Before the CPU is installed, the
mainboard must be placed on a flat
surface. You should be able to insert
the CPU with minimal, but firm,
pressure. Do not press down hard on the
CPU.
In Figure 2-6, you can see the CPU and the
ZIF socket. Notice that the arm of the ZIF
socket is up. When this arm is up, the CPU
is unlocked from the socket and allows
you to remove or install a CPU. As the ZIF
socket is keyed to the processor that you
are using, you will only be able to install
the CPU one way, thus eliminating the
chance for error. 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. 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.
important!
Figure 2-6
Figure 2-7
Push down lightly on the CPU, and lower the arm on the ZIF socket to secure
the CPU. A squeaking noise is normal as the arm lowers. After the CPU is
securely seated, install the appropriate cooling device (Figure 2-7). T yan
strongly recomends a heatsink/fan combination. Consult with your case
manufacturer for other cooling options.
http://www.tyan.com

Figure 2-8
Locate the cooling fan connector (e.g. CPU Fan, Fan1) on the motherboard. Plug
the CPU’s cooling fan cable into the cooling fan connector on the board. There
will be a plastic clip assembly similar to that of the ATX power connector that will
force you to connect the fan cable correctly (see Figure 2-8 above).

connector. In Figure 2-9 on
the previous page, you can
see how the IDE cables
should look when they are
connected to your hard
drive. Notice how Pin 1
(denoted by a red stripe) is
connected so that it is next
to the power connector of
the drive. The primary IDE
connector is black; the
secondary IDE connector is
white.
Pin 1
In most cases, this is the
proper way of connecting
Figure 2-10
your IDE cable to the harddrive. Figure 2-10 shows the IDE cable properly
connected to the motherboard. Contact your hard disk drive manufacturer or
documentation for more information.
A TA-66 IDE hard drives require a special IDE cable which has additional
grounding wires. The cable is sold separately, and is required when using
ATA-66 drives. This cable will also support all legacy IDE drives.
Some symptoms of incorrectly installed HDDs are:
• Hard disk drives are not auto-detected: may be a Master / Slave problem
or a bad IDE cable. Contact your vendor.
• Hard Disk Drive Fail message at bootup:may be a bad cable or lack of
power going to the drive.
• No video or beeps on bootup: usually means the cable is on backwards.
• Hard drive lights are constantly on: bad IDE cable or defective drives/
motherboard. Try another HDD.
• Hard drives do not power up: check power cables and cabling. May
also be caused by a bad power supply or IDE drive.
