Introduction
Overview
The S1857 Trinity 371 is a quality, high performance motherboard designed for
Socket 370 Intel Celeron and Slot 1 Intel PII/ PIII microprocessors. The Trinity
371 utilizes the Intel 440BX AGPset with AMI BIOS (S1857-B & S1857A-B) or
a VIA VT82C693A with Award BIOS for S1857 & S1857-A models. S1857 can
support Celeron/ PII/ PIII CPU speeds of 300MHz through 600MHz, and host
bus speeds of 66MHz to 133MHz.
( The VIA chipset versions bus speed is Auto-Determined by the CPU. The
BX version can support 133Mhz by overclocking the chipset but it is not
recommended by Intel
TM
and Tyan.)
The S1857 motherboard, 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 in an ATX form factor offers far more features and
expandability than Micro ATX models. 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 371. With I/O
and drive controller support built onboard, the one AGP slot, six PCI and one

products along with FAQs, distributors list, drivers, and BIOS setting explanations.
Icons
In order to help you navigate this manual and set up your system, we have
added several icons to our format.
This icon alerts you to particularly important details regarding the
setup or maintenance of your system. This icon often appears next
to information that may keep you from damaging your board or
system. While we will often point out the most vital paragraphs in a
chapter, you should always read every word in the text. Failing to do so can
lead to exasperation and expense.
Wherever possible, we have included step-by-step instructions for
setting up your system, which are indicated by this icon. However, it
is in your best interest to read an entire section (and perhaps the
entire manual) before you begin to fiddle with your motherboard.
While we have alerted you to potential dangers in several places in
the manual with this icon, these warnings should not be regarded as
the whole of your safety regimen. Never forget that computers are
electrical devices, and are capable of delivering a shock. Prevent damage to
yourself and to your board: always ensure that your system is turned off and
unplugged whenever you are working with it, and that you are equipped with a
static safety device.

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).
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

INSTALL
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!
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. 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 example of pin connections.
Figure 2-1 Figure 2-2
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 full-page map of the motherboard can be found on the next two pages.

1. Setting Jumpers
1-A. CPU Speed Settings (Jumpers JP10, JP11, JP12, JP13)
There are two steps to set the CPU speed. First, set the clock multiplier with
jumpers JP10 -13 according to the specification of your CPU using the chart
below. After the system is ready to boot up you will need to set the bus speed
in the BIOS setup. This is covered in detail in Chapter 3 of this manual.
Presently all Celeron CPUs use a 66MHz bus speed. (Tyan does not recommend operating CPUs, memory, or PCI Bus at higher than rated speed. Tyan
takes no responsibility for any problems related to overclocking any bus or
component on the system board.)

If you have been locked out of your system because you forgot your password or set the CMOS incorrectly, follow the instructions below.
1. Power off the system
2. Set jumper JP2 to pins 2 and 3
3. Wait for 2 seconds, then return jumper JP2 to pins 1 and 2.
4. Power on the system again.
By following this procedure, you will erase your password and reset the
CMOS to the BIOS defaults.
1-H Fan Speed Detect
When using Intels LANDesk system management software, you may monitor
the status of the CPU Fans by connecting them to the Fan1 connector. You
will NOT be able to monitor your CPU fan with the other Fan connectors.
1-I Soft Power Connector
The Soft Power Connector is part of
jumper block J16. The Trinity 371 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-J Sound disable (JP17)
By closing this jumper you will disable the on-board sound support which is
routed through the Creative Labs ES 1373 PCI sound chip.
The settings are closed (No onboard sound) or Open (Default).

1-L 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-M Creative Labs Audio Connectors
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 MPEG connector
(J20) is for DVD and TV cards; the VIDEO connector is (J22); the CD connector
(J23) is for CD-ROMs.
1-N External SMI
The EXTSMI (External System Management Interface) connector, jumper JP16,
is used by some plug-in cards. Certain applications associated with these plugin cards use the interface for hardware control and queries.
1-O Intrusion Alarm Connector
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.
1-P 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 440BX or Via Apollo Pro Plus 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).
S1857 Trinity 371

Flash EEPROM
The Trinity 371 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 68).
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 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 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.

important!
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.

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.
Place the DIMMs in an anti-static bag as soon as you remove them to avoid
static damage.

The Trinity 371 uses a 64-bit data path from memory to CPU and can accommodate up to 768MB (1.5GB for VIA) of SDRAM. The 168-pin DIMMs (Dual Inline 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 automati-
cally detected, so there is no need to set any jumpers.

Some details of memory installation:
At least one unbuffered DIMM must be installed for the system to POST.
The mainboard supports 32MB, 64MB, 128MB SDRAM; and supports
256MB registered SDRAM DIMM modules, but not in combination with
non-registered modules.
PC-100 DIMM is required if CPU bus speed is at 100MHz
The table below shows some of the possible memory configurations. Not all
possible configurations are listed.
Cache Memory
Celeron A processors have the L2 (Level 2) cache built into their architecture,
so there is no need for an L2 cache on the motherboard. The Celeron processor has a physical L2 cache size of 128KB and a cacheable memory area of
512MB.

4. Installing the CPU and Cooling Fan
Socket 370 type Celeron processors (300 through 533MHz) and Pentium II/III can
be used on the Trinity 371. Please refer to page 17 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.
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.
Note: If two CPUs
are installed
simultaneously,
only the CPU in the
socket will be
detected. Further-
more, the socketed
CPU will have its
multiplier locked at
2.0. In order for you
to change the
multiplier, you
should only use one
CPU at a time.
Figure 2-8
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. Tyan strongly
recomends a heatsink/fan combination. Consult with your case manufacturer
for other cooling options.

Chapter 2
Board Installation
Currently, two types of cooling mechanisms are produced for Pentium II processors: active (figure 2-9a) and passive (figure 2-9b). These two types of cooling
methods essentially perform the same function. The active cooler is equipped
with a cooling fan and heat sink, while the passive cooler is simply a larger heat
sink with no fan. The type of cooler used has no effect on performance, and both
types can be installed in the CPU slot on the Trinity 371 board.
Currently S1857 does not support some older Slot 1, 66Mhz bus Pentium IIs
that use a 2.8 core voltage. Please refer to this link for the most updated
information on CPU support for the Trinity 371.
Installing CPU Retention
Modules
Installation of a Pentium II / III/
Celeron processor requires a CPU
retention module, which is first
secured onto the motherboard.
Figure 2-11 Pentium II Slot Connector and Key Pin
Note: Tyan provides a variety of
retention modules. For detailed
installation procedures of your
module, please refer to Appendix 2
located at the back of the manual.

To attach the retention module, place the motherboard on a flat surface. Locate
the key pin on one end of the CPU slot on the board. Then carefully line up the
key notch on the retention module with the key pin on the CPU slot(the key
pin on the CPU slot indicates the correct orientation of the CPU) See Figure 211 on the previous page.
Drop the retention module (Figure 2-12
right) down over the CPU slot so that
the retention module sits flat against the
motherboard. Secure the module with
the pins or screws provided.
Figure 2-14 below shows a side view of a retention brace securing both sides
of the SECC2 CPU. When both sides are properly positioned, press both
braces against the sides of the CPU and carefully lift them over the CPU slot
on the motherboard.

Line up the retention brace with the holes provided on the motherboard. At
the same time, make sure the CPU is lined up with the CPU slot. Lower the
CPU onto the motherboard. The mountings on the retention brace should fit
through the holes of the motherboard and the CPU should fit into the slot.
See Figure 2-15). Secure the retention brace. The end result should look like
Figure 2-16.

If you have an active cooler, you will also need to connect the CPUs cooling
fan cable to the cooling fan power connector on the board. Locate the cooling
fan connector (e.g. FAN1) on the motherboard. Plug the CPUs 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 2-17 below.
When removing the CPU, pull lightly on the pegs sucuring the retention brace
and remove the CPU and retention brace at once. This may require careful firm
tugs to pull the CPU out of its slot.
Note: The CPU fan activates after the VGA card is initalized and not when the
system boots up, therefore you may experience a 5 second delay before the
CPU fan is enabled.
5. Connecting IDE and Floppy Drives
The colored stripe on a ribbon cable should face toward the battery on the
motherboard. Make sure that 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. In most cases, this is the
proper way of connecting your IDE cable to the hard drive. Figure 2-18 on the
next page shows the IDE cable properly connected to the motherboard.
Contact your hard disk drive manufacturer or documentation for more information.

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 onbootup: usually means the cable is on back
wards.
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 a bad power supply or IDE drive.
