Introduction
Overview
The S1854 Trinity 400 is a quality, high performance motherboard designed for
Socket 370 Intel Celeron and Slot 1 Intel PII/ PIII microprocessors. The Trinity
400 utilizes the VIAVT82C694X withAward BIOS for S1854 & S1854-A
models. S1854 can support Celeron/ PII/ PIII CPU speeds of 300MHz through
600MHz, and host bus speeds of 66MHz to 133MHz, the VIA chipsets bus
speed is Auto-Determined by the CPU. The S1854 motherboard, with built-in
4x AGP slot, provides high performance capabilities that are ideal for a wide
range of demanding applications such as CAD, CAM, CAE, desktop publish-
ing, 3D animation, 3D Games 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 400. With I/O
and drive controller support built onboard, the one AGP slot, six PCI, a total of
seven usable are free for numerous add-on expansion cards. Remember to take
a look at TYAN Computers web site located at
http://www.tyan.com. There you can find information on all of TYANs prod-
ucts 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). 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.

INSTALL
Here are some precautions you should follow when installing your mother-
board:
(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 mother-
board 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 NOTAPPLY POWERTOTHE BOARD IF ITHAS 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, 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 dis-
charge 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 theFigure 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.

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 recom-
mend 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.)

1-G Fan Speed Detect
When using Intels LANDesk system management software, you may monitor
the status of the CPU Fans by connecting them to the Fan1 and/or Fan2
connectors. You will NOT be able to monitor your CPU fan with the other Fan
connectors.
1-H 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-I Hardware Reset Switch Connector Installation
The Reset switch on your cases
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-J 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 TDAconnector (J21) is for modem audio; the VIDEO connector is
(J22); the CD connector (J23) is for CD-ROMs.

1-K Chassis 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 systems case.
1-L 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
LEDs can still be used on J16 where pin 13 would be for the Ground pin.
1-M Suspend to RAM
The Trinity 400 has Supend to Ram; advanced power management function.
The jumper JP20 enables and disables this function.
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 133AAGPset. 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 installa-
tion 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

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 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 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.
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.

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