1.4 Technical Support

If a problem arises with your system , you should turn to your dealer for he lp first. Your system has most
likely been configure d by t hem, a nd the y should have the best ide a of wh at har dware and so ftwa re your
system contains. Hence, they shou ld be of the mo st assist anc e. F urt her more, if you p urch ase d you r sys­tem from a dealer near you, you can actual ly bring your system t o them to have it service d, instead of
attempting to do so yourself (which can have expensive consequences).

Help Resources:

1. See the FAQ and beep codes section of this manual.

2. See the Tyan website for FAQ, bulletins, driver updates, and other
information: http://www.tyan.com

3. Contact your dealer for help BEFORE calling Tyan.

4. Check the Tyan user group: alt.comp.periphs.mainboard.tyan

34-pin floppy cable

ATA-66/100 IDE cable (with blue connector)

Trinit y 450 use r’s ma nua l

Tyan driver CD

2.2 Installation

You are now ready to install your mothe rb oar d. T he m oun ti ng ho le p atte rn of the Trinity 450 matche s the
ATX board specifications, so your chassis must be capa ble of supporting an ATX board (check the moth­erboard dimensions provided on p. 5).

2.3 How to install our products right.. the first time.

Question: what’s the first thing I should do?

The first thing you should do is read the user’s manual. It contains important information wh ich will make
configuration and setup much easier, as well as provide information on device installation and component
set up.. By reading through the manual completely before installing your motherboard, you will have a
complete overview on the installation.

http://www.tyan.com

Here are some safety tips:

(1) Ground yourself properly before removing your motherboard from the antistatic bag. Unplug

the power from your computer power supply and touch any metal part on the computer case. (You

might also want to 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 pl ace it on a grounded a ntistatic surface, com ponent side up.
Inspect the board for damage.

NOTE: DO NOT APPLY POWER T O THE BOARD IF IT HAS BEEN DAMAGED!

Press down on any of the socketed ICs if it appear s that they are no t properly sea ted (the boa rd should
still be on an antistatic mat). Do not touc h the bottom of the boa rd. Remember, don’t take any elect ronic
device out o f it s p ro t ect i v e ba g un t i l y o u a r e r e ad y t o a c t ual l y i n s tal l i t int o t he c o mp ute r ca s e . If y o u do n ot
ground yourself, you r isk zappi ng the mothe rboard o r adap ter card . Sub sequen t prob lems may not arise
immediately because electrostatic discharge, unlike physical damage, causes the device to fail over time.

2.4 Quick References for Jumpers

In this manual, the term “close d” and “on” are used wh en referring to jumpers (or jumper pins) that are
active; “open” and “off” a re u s ed whe n re fer ring to j u mp ers (or j um per pin s) that are inactive. See Figure

2.0a and Figure 2.0c for examples of “on” and “off” pins and jumpers.

Jumpers and pins are connec ted by slipping the plastic jum per connector over the top of tw o adjacent
jumper pins (indica ted b y 1-2 or 2-3 ). Th e met al r od insid e the plast ic shell bridg es the gap b etween the
two pins, completing the circ uit. See Figure 2.0b and Figure 2.0d for more examples of 3-pin jumper
connections. NOTE: The small number “1” indicates pin 1.

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. Full page maps of the motherboard can be found on the next two pages.

2.7 Mounting the Motherboard into the Chassis

Your chassis may include mounting hardware. If mounting hardware w as included, yo u can use the fo l­lowing examples to help you in installing your motherboard into the chassis.

The chassis may have com e wit h th e stud s int egr ate d in to t he cha ssis wa ll, so in t hose ca ses you wou ld
only need to use scre ws (p ossibly i nclude d with you r chass is) to instal l the m other board . See the ex am­ples (Figure 2.0, shown below) for more details.

If the chassis includes mounting hardware without the studs pre-installed, then you will need to install the
motherboard using the mounting hardware as shown in t he examples below. Remember not to over­tighten any of the sc rews, or you might risk breaking i nternal tr aces in the su rroundi ng area, or damage
the motherboard in some ot her way .

Other examples of how to install your motherboard using other hardware (that may or may not have been
included with your chassis) are shown below.

2.8 Installing Memory

Please keep in m ind t hat although some m em or y m od ules m ay ap pear to be high -q ualit y, they may con­tain inferior or subs tandard parts . The type of m emory you choo se to install sho uld be checked ag ainst
the memory compatibility list, which is available from Tyan’s website at http://www.tyan.com

Memory Installation Procedure

Here are some details of memory installation for this board:

At least one unbuffered DIMM must be installed for the system to POST.

The motherboard supports 64MB, 128MB, 256MB, and 512MB PC100/133 SDRAM.

All installed memory will be automatically detected, so there is no need to set any jumpers.

The motherboard supports up to 1.5 (3 DIMMs)* or 2 GB (4 DIMMs)* of memory.

Step

Step

Step

* 2.0GB total memory @ 4 unbuffered DIMMs only, when using 100MHz SDRAM

1.5GB total memory @ 3 unbuffered DIMMs only, when using 133MHz SDRAM
Check the Tyan website for details on memory compatibility: http://www.tyan.com

Insert the DIMM by pushi ng the module in to the socket with e ven force. Do not insert one

1

end and then the other : install the whole modul e at once or you might bend the DIMM pins.
Make sure the DIMM is securely seated.

Line your module up so that the pins fit into the socket. There is only one way your DIMM can

2

fit properly. Make sure that the short row of pins is lined up with the short gap in the DIMM
socket.

Lock the DIMM into place by pu shing the clips back on either end of th e socket onto the

3

notches in the ends of the DIMM (see pictures below for details).

16

http://www.tyan.com

Removing a DIMM

Removing a DIMM is just the reverse: simpl y pu ll back the cl ips fro m the DIM M (see pictur es bel o w), and
carefully pull the module straight out. Place the DIMMs in an anti-static bag as soon as you remove them
to avoid static damage.

2.9 Installing the CPU and Cooling Fan

Intel Pentium III FC-PGA processors (500 MHz through 1 GHz) or a single FC-PGA type Celeron proces­sor can be used on this board. For more information on CPU compatibility, check Tyan’s website at:
http://www.tyan.com.

When installing your CPU, remember the following:

The CPU is a sensitive electronic component and can easily be damaged by static electricity

Do not touch the CPU pins with your finger s

You should be able to insert the CPU into the socket with virtually no force

Do not press down hard on the CPU as you might bend or break pins, or otherwise damage the
CPU

The CPU voltage will automatically be detected by the motherboard, so there is no need to set any jump­ers or BIOS setting.

Installing the Intel Pentium III FC-PGA CPU

Before installing the CPU, check it for any visible damage. Make sure none of the pins ar e bent or miss­ing. Be sure where Pin 1 is on both the CPU and the socket. The following steps each have a correspond­ing picture next to it to help guide you through the installation.

Installing the Cooling Fan

After the CPU has been installed, you will need to install the proper co oling de vice for the CPU. This
device, a heatsink/fan com bination , can be purc hased at ma ny compute r retail store s. Installat ion of the
cooling device may vary depe nding on the fan manufacturer ’s design. You should also take space into
consideration when in stall a c ooli n g d evice : m ake su re th e cooling device is no t to o big, or e l se y ou ma y
end up damaging components around the CPU socket.

Tyan highly recommends that you use some type of
thermal compound (available from computer retail
stores), between the CPU and heat sink, to maximize dis­tribution of heat away fr om the CPU. Please use extra
caution when installing any type of clamp-style fan, or
else damage may occur to the CPU sock et, and/or the
CPU itself. See Figure 2.2 (see right) for a n example o f
how to connect the cooling fan’s power supply. Another
diagram has also be en pro vi de d be low, to aid in C PU fan
installation onto the socket. Check with your cooling
device vendor for more details about installation.

2.11 Installing Add-on Cards

There are a few rules you need to follow when installing add-on cards. In order to assure proper operation
and a quick installation, adhere to the following guidelines:

If you are going to install a PCI-bus interface card on your system, be aware that any one of the
five PCI slots can support a Master or Slave device.

NEVER force a card into a slot. If it doesn’t fit, look at the socket on the motherboard to make

sure there are no wires or other obstructions to the slot.

NEVER plug an ISA card into a PCI slot. You will void your warranty and damage your system

board if you do this.

When plugging the card in, especially when installing long cards, try to push the entire card in at
one time. Don’t force one end of the card into the socket first and then the other, or a rocking
motion between the card and the slot might occur, and could damage the pins within the socket.

Make sure the cards are seated securely into their slots.

Before turning on the system, make sure no cards are touching.

When installing the add-on cards, make sure the cards are installed with even force; do not insert one
end and then the other. See the before (Figure 2.6a) and after (Figure 2.6b) example ins ta ll a t ion i mag es
below for details.

2.12 Connecting PS/2, USB, and Serial Devices

This motherboard includes ports for PS/2 mouse and keyboard, Universal Serial Bus (USB) devices, and
serial and parallel* devices. Please note that the upper PS/2 port is the mouse port, and the lower PS/2
port is for the keyboard (see Figure 2.7 below).

The PS/2 connectors are probably quite familiar to you, while the USB connectors may not be. A USB
port can function as a serial, parallel, mouse, keyboard, display, or joystick port. It is capable of supporting
up to 127 daisy-chained peripheral devices. All external ports are labeled in Figure 2.7, shown below.

2.13 Connecting the power supply

This motherboard requires an ATX power supply. Tyan recommends using one that conforms to industry
standard Revision 2.01. The images below show the ATX power connector before (Figure 2.8a) and after
(Figure 2.8b) it has been plugged in. The clip on the power connector should lock over the tab on the
onboard connector. You shouldn’t be able to plug the power connector in any other way but just to be
safe, make sure it looks like Figure 2.8b. Make certai n that you do not miss connecting any of the pins
because if you do, you will void your warranty and possibly cause damage to yourself and/or your moth­erboard when the power is turned on. After connecting the power, make sure the connector is seated
firmly into its socket so it will not become loose or fall off when the computer is jostled or moved.

You are done!

Other than checking the jumper settings and cable connections, and putting the case back on, you are
done. Installing a new motherboard may seem difficult, but by following these directions, you should have
a fairly uneventful time installing our products. If you do encounter problems, your dealer will be able to
help you, or you can consult one of our many technical support resources (see p. 7).

2.14 Frequently Asked Questions (FAQ)

Q: My system sometimes becomes unstable. How should I check the system?
A: The first thing to do is to check and see if you have any device conflicts related to the IRQ, or DMA. If
you are using Microsoft Windows, the Control Panel is a good place to start investigating the conflict.
Please consult your operating system documentation for details. Secondly, slowing down the memory tim­ing in the BIOS’ chipset setup section will help the situation as well. Many memory modules are not suit­able for high performance systems and are probably the main source of your problem. Also check to
make sure you are using an ATX 2.01 compliant or better power supply. Lastly, make sure the mother­board is receiving adequete cooling.

Q: I have a question about memory compatibility; what memory will work on my motherboard?
A: Memory compatibility information can be found on Tyan’s website at: http://www.tyan.com

Q: Where can I get additional accessories for my Tyan motherboard?*
A: You can purchase additional accessories such as USB cables, as well as other Tyan-approved acces­sories at the Tyan Computer Online Store: http://www.etyan.com

Q: Where do I get pinout information for my motherboard?
A: Pinouts of certain headers are available on the Tyan website: http://www.tyan.com

Q: My motherboard is dead, how do I return it?
A: Contact the place of pu rchase or your distributor for assistance to return the motherboard for service.

Q: How do I upgrade my BIOS?
A: Check the section about the Flash Utility (see p.37) for information on upgrading your BIOS. BIOS
update files, flash utilities, and instructions on how to install them are also available from the Tyan website
at: http://www.tyan.com

Q: Why do I get a “CMOS checksum invalid” error message during POST?
A: If you get the above error message or “Invalid configuration, run Setup” message, it is an indication that
the CMOS battery needs to be changed. Contact your dealer for assistance. Once you’ve replaced your
battery, don’t forget to check the Clear CMOS section (see p.12) so that you can reset your CMOS.

* If your chassis supports frontside USB, it will usually come with those cables. Please check if your
chassis supports a frontside USB port configuration. Check with your chassis vendor for more details.

Chapter 3: BIOS Setup

Introduction to the BIOS setup

The BIOS is the basic input/output system, required by the computer to perform functions such as CPU
and hard drive support. This chapter describes different settings for Award BIOS that can be used to con­figure your system.

The BIOS section of the manual is subject to change without notice and is provided here for refer­ence purposes only. The settings and configurations of the BIOS are current at the time of print,
and therefore they may not be exactly the same as that displayed on your screen.

The manual describes the Award BIOS setup program. The setup program lets you modify basic configu­ration settings. The settings are then stored in a dedicated battery-backed memory, called NVRAM, that
retains the information when the power is turned off.

The Award BIOS in your computer is a customized version of an industry-standard BIOS for IBM
PC AT-compatible personal computers. It supports Intel x86 and compatible processors. The
BIOS provides critical low-level support for the system central processing, memory, and I/O sub­systems.

The BIOS has been customized by adding important, but non-standard, features such as virus and
password protection, power mangement, and detailed fine-tuning of the chipset controlling the
system. The rest of this manual is intended to guide you through the process of configuring your
system using the Award BIOS setup program.

Starting Setup

The BIOS is immediately activated when you first turn on the computer. The BIOS reads system configu­ration information in CMOS RAM and begins the process of checking out the system and configuring it
through the Power-On Self Test (POST).

When these preliminaries are finished, the BIOS seeks an operating system on one of the data storage
devices (HDD, FDD, etc.) and if one is found, the BIOS will launch that operating system and hand control
of system operations to it. During POST, you can start the setup program by pressing the [DEL] key when
the “Press DEL key to enter BIOS setup” message appears on the screen.

In Case of Problems

If you discover that you have trouble booting the com puter after making and saving changes with the
BIOS setup program, you can restart the computer by either:

Pressing [CTRL]+[ALT]+[DEL] (all three keys at the same time), or

Holding the power button down until the computer shuts off, then reset the CMOS (see p. 15)

Trinity 450 S2507S

27

The best advice is to alte r only sett ings th at you th oroughl y under stand. I n particu lar, do not change set­tings in the Chipset sc reen unless you are absolutely sure that you need to. The Chipset defaults were
carefully chosen for the best performanc e and r eliability. Even a seem ingly sm all change to the Ch ipset
setup may cause the system to become unstable.

Setup V ariations

Not all systems have the same setup program. While th e basic look and functio n of the setup program
remains more or less the same for all system, the appearance of your Setup screen may differ from other
Award BIOS screens. Each system design an d chipset combination require custom configurations. In
addition, the final appearance of the setup program depends on your system designer. You system
designer can decide tha t certain item s should not be available for use r configurati on, and remove t hem
from the BIOS setup program.

General Help

At any time, you can pres s [F1] to bring up a Gen era l Hel p scre en in ca se yo u wa nt to l ea rn the sho rtcu t

Note: If you experience problems with setting up your system, always check the following things in the

following order:

CPU, MEMORY, VIDEO

By checking these items, you will most likely find out what the problem might have been when setting up
your system. For more info rmation on troubleshooting, check the Tyan website a t http://www.tyan.com

4.1 Beep Codes

Fatal errors, which halt the boot process, are communicated through a series or audible beeps. For exam­ple, if the Award BIOS POST can initialize the video but an error occurs, an error message will be dis­played. If it cannot display video, it will convey a series of beeps.

If you hear one long beep followed by two short beeps, then a video problem has probably occured and
the BIOS is having difficulty initializing the video display. Any other beep sequences that may or may not
occur are probably due to memory problems.

4.2 Displayed Error Messages

If an error occurs after the system display has been initialized, an error message will be displayed as fol­lows:

Appendix I: Glossary

ACPI (Advanced Configuration an d Power Interface): a pow er m anage ment s pecific ation th at al lows the

operating system to control the amount of power distributed to the computer’s devices. Devices not in use
can be turned off, reducing unnecessary power expenditure.

AGP (A

ccelerated Graphics Port): a PCI-base d inte rfa ce whic h was de sign ed spe ci fical ly for dem and s of
3D graphics applications. Th e 32-bi t AGP chann el directl y links the grap hics con troller to the main mem­ory. While the channel runs at only 66 MHz, it supports data transmission during both the rising and falling
ends of the clock cycle, yielding an effective speed of 133 MHz.

AMR (A

udio Modem Riser) : a mod em tha t can b e used on Intel Refe rence Mothe rboard platfor ms using
Intel’s core logic chipsets supporting AC-link 2.1. It supports fax and all data feedback modes. It provides

AT: the original form factor of IBM’s PC.

ATAPI (AT

the disk controller on the dev ice itsel f. It all ows CD -ROMs an d tape dr ives to be co nfigure d as maste r or
slave devices, just like HDDs.

ATX: the form factor designed to repl ace the AT form factor. It improves on the AT design by rotating the
board 90 degrees, so tha t the IDE connecto rs are close r to the drive b ays, and the CPU is closer to the
power supply and cooling fan. The keyboard, mouse, USB, serial, and parallel ports are built-in.

Bandwidth: refers to carrying cap aci ty. The greater the ban dw idt h, th e m ore dat a the bus, phone line, or
other electrical path, can carry. Greater bandwidth, then, also results in greater speed.

BBS (B
center for users to post messages and access information.

BIOS (B
instructions for controlling your computer’s hardware. Both the operating system and application software
use BIOS routines to ensure compatibility.

Buffer: a portion of RAM which is u sed to te mp ora ril y sto re d ata , usu all y fr om an a pplic a tion , tho ugh i t is
also used when printing, and in most keyboard dr ivers. The CPU can manipulat e data in a buffer before
copying it, all at once, to a disk drive. While this improves syst em performance --- readin g to or writing
from a disk drive a single time is much fa ster than doing so repeatedly --- there is also the possi bility of
losing your data should the system cr ash. Inf ormatio n sto re d in a bu ffer is te mp orarily st ore d, n ot p erma­nently saved.

Bus: a data pathway. The term is used especially t o refer to the connec tion bet ween the pr ocessor and

system memory, and between the processor and PCI or ISA local buses.

Bus mastering: allows peripheral devices and IDEs to access the system memory without going through
the CPU (similar to DMA channels).

Cache: a temporary storage area for data that will be needed often by an application. Using a cache low­ers data access times, since th e ne ed ed i n for mat ion is stored in the SRAM instea d o f in the sl ow DR AM .
Note that the cache is also mu ch sm al le r th an your re gu lar m em or y: a typi ca l cach e size i s 51 2KB , wh ile
you may have as much as 1GB of regular memory.

Cache size: refers to the physical size of the cache onboard. This should not be confused with the cache­able area, which is the total amoun t of m emory wh ich ca n be sc anned by the syste m in se arch of da ta to
put into the cache. A ty pical setup would b e a ca che si ze o f 512KB , an d a ca cheable area of 5 12MB. In
this case, up to 512KB of the main memory onboard is capable of being cached. However, only 512KB of
this memory will be in the cache at any given moment. Any main memory above 512MB could never be
cached.

Closed and open jumpers: jumpers and jumper pins are active when they are “on” or “closed”, and inac­tive when they are “off” or “open”.

DIMM (D
need to be installed in pairs.

DIMM bank: sometim es called DIMM sockets, because the physical slot and th e logical unit are the

bank.

DMA (D

GLOSSARY

I/O (Input/Output): the connection between your computer and another piece of hardware (mouse, key-

board, etc.)

IRQ (Interrupt Request): an electronic request that runs from a hardware device to the CPU. The interrupt
controller assigns priorities to incoming requests and delivers them to the CPU. It is important that there is
only one device hooked up t o each IRQ line; d oubling u p devices o n IRQ lin es can lock u p your sys tem.
Plug-n-Play operating systems can take care of these details for you.

ISA (I

ndustry Standard Architecture): a slower 8- or 16-bit bus (data pathway).

Latency: the amount of time that one part of a system spends waiting for another part to catch up. This is
most common when the syste m s end s da ta o ut t o a per iphe ra l device, and it waiting for th e p erip her al to
send some data back (peripherals tend to be slower than onboard system components).

Mirroring: see RAID.

NVRAM: ROM and EEPROM are both examples of Non-Volatile RAM, memory that holds its data without

power. DRAM, in contrast, is volatile.

OEMs (O
and hardware inside their case and sell them.

Parallel port: transmits the bits of a byte on eight different wires at the same time (that is, in parallel form,
eight bits at the same time).

PCI (P
bus. Local buses are those which operate within a single system (as opposed to a ne twork bus, which
connects multiple systems).

PCI PIO (PCI P
modes use the C PU for dat a transfer ( in contrast, D MA channel s do not). PCI refers to the type of bus
used by these modes to communicate with the CPU.

PCI-to-PCI bridge: allows you to connect multiple PCI devices onto one PCI slot.

Pipeline burst SRAM: a fast secondary cache. It is used as a secondary cache because SRAM is slower

than SDRAM, but usually large r. Data is cached first to the fa ster prim ary cache, and then, when the pr i­mary cache is full, to the slower secondary cache.

Pipelining: improves system perform ance by allowing the CPU to begin exe cuting a second instru ction
before the first i s com pleted. A pipeline can be l ike ned to an assembly li ne , with a given part of th e p i pe­line repeatedly executing a set part of an operation on a series of instructions.

PM timers (Pow e r M ana gem en t time rs) : software timers that count down the number of seconds or min­utes until the system times out and enters sleep, suspend, or doze mode.

PnP (P

lug-n-Play): a design standard that has become ascendant in the industry. Plug-n-Play devices
require little set-up to use. Novice end use rs can simply plu g them into a compu ter that is run ning on a
Plug-n-Play aware operatin g system ( such as Win dows 98), and go to wo rk. Devices a nd oper ating sys­tems that are not Plug-n-Play require you to reconfigu re your system each time you ad d or change any
part of your hardware.

Striping: see RAID.

RAID (R

edundant Array of Independ ent Disks): a way for the same dat a to be stor ed in different places
on many hard drives. B y using this m ethod, the data is sto red redundan tly, also the multiple hard drives
willl appear as a single drive to the operating system. RAID level 0 is is known as striping, where data is
striped (or overlapped) across multiple hard drives, but offers no fault-tolerance. RAID level 1 is known as
mirroring, which stores th e data within at least two hard dr ives, but does not stripe. RAID level 1 also
allows for faster access time and fault-toleranc e, since either hard dr ive can be read at the s ame time.
RAID level 0+1 is both str iping and mir roring, providing fault-toler ance, striping, an d faster access all at
the same time.

RAM (R

andom Access Memory): technically refers to a type of memory where any byte can be accessed
without touching the adjacent data, is ofte n used to refer to the system’s main memory. This memory is
available to any program running on the computer.

ROM (R

ead-Only Memory): a storage chip wh ich contains the BIOS ; the basic instructions req uired to

boot the computer and start up the operating system.

SDRAM (S
addresses open simultaneo usly. By transferring data alternat ely from one set of ad dresses and th en the
other, SDRAM cuts down on the delays associated with non -synchronous RAM, which mus t close one
address bank before opening the next.

Serial port: called as such because it tran smits the eight bits of a byte of data along one wire, and
receives data on another single wire (that is, the data is transmitted in serial form, one bit after another).

SIMM (S
must be installed in pairs, and do not have the carrying capacity or the speed of DIMMs.

SIMM bank/socket : SIMM s ockets are the physical slots into which you install SIM M modules. A pair o f
SIMM sockets form a SIMM bank, and act as one unit. If only one socket is filled, the bank will not op er­ate.

Sleep/Suspend mode: in this mode, all devices except the CPU shut down.

SRAM (Static RAM): unlike DRAM, thi s type of RAM doe s not need to be refreshed in o rder to preven t

data loss. Thus, it is faster, and more expensive.
Standby mode: in this mode, the video and fixed disk drive (usually the HDD) shuts down; all other
devices continue to operate normally.

UltraDMA/33/66/100: a fast version of the old DMA channel. UltraDMA is also called UltraATA. Without
the proper UltraDMA controller, your system cannot take advantage of the higher data transmission rates
of the new UltraDMA/UltraATA HDDs.

USB (U
