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 install 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
TechnicalSupport
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.
Helpresources:
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 BEFOREcalling Tyan.
4. Check the Tyan user group: alt.comp.periphs.mainboard.tyan

Here are some precautions you should follow when installing your mother-
board:
(1) Groundyourselfproperlybeforeremovingyourmotherboard
fromthe 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) Holdthemotherboardbyitsedgesanddonottouchthebottomof
theboard.
(3) Avoidtouchingmotherboardcomponents,ICchips,connectors,
andleads.
(4) Avoidtouchingpinsofmemorymodulesandchips.
(5) Placemotherboardonagroundedantistaticsurfaceoronthe
antistaticbag.
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.
DONOTAPPLYPOWERTOTHEBOARDIFITHASBEENDAMAGED!
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 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 Figure2-2 for more example of pin connections.
Figure 2-1 Figure2-2
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 the BUS Speed is auto-detected.
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 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 case’s display panel provides you with the Hard-
ware 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
theCreative LabsES1373 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
VIDEOconnector is (J22);the CD
connector(J23) is for CD-ROMs.
1-J 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-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
LED’s 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
(SonyCR2032).
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.
