Introduction
Overview
TheS1590S-100 (S1590)Trinity 100ATis aquality, highperformancemainboard
designed for Socket 7 microprocessors. This mainboard utilizes the VIA MVP3
100MHzAGPset and host bus speeds of 66MHz to 100MHz. For CPU speed
support, please refer to the CPU Compatibility Chart inTyan’s website
(http://www.tyan.com/support/html/socket_7_compatibility.html). TheTrinity
100AT also has 100MHz Front Side Bus support, which allows you to take full
advantageof 100MHzSDRAMmemory modules.
The S1590 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 a BabyAT form factor. Some of the features
included are onboard dual channel PCI PIO, Bus Master IDE and UltraDMA/
33, onboard floppy controller, and onboard high speed I/O.
Flexibility and expandability have been designed into theTrinity 100AT. With
I/O and drive controller support built onboard, the one AGP slot, four PCI and
four ISA slots (one shared, eight usable) are free for numerous add-on expan-
sion cards.

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.

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 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).

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
discharge damage, unlike physical damage, causes the device to fail over time.

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 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 Figure2-2 for more examples of pin connections.
Thetables andmapson the followingpageswill helpyouset the jumpersforCPU
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
**Default Setting(2.2V)
The CPU speed is controlled by setting the bus speed and the multiplier with
the jumpers described above that are appropriate for your CPU and memory.
You must have a 100MHz processorAND PC/
100 memory to run at a bus speed of 100MHz.
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 componenet
on the system board.

JP11 is used to set CPU I/O voltage. Most newer P55C type CPUs such as AMD K6/
K6-2 have 3.3V I/O voltage and a lower core voltage, so this jumper should be
OFF. For certain older P54C type CPUs the Core voltage is the same as the I/O
voltage so this jumper should be closed (on). Check the specs on your CPU
before you set this jumper.
Note: AGPClockSpeed is 66MHz.
CPU Clock Speed is set in
section 1-A on previous page.
**Note: JP7 and JP14 are provided on
some S1590 boards. If your board does
not have JP7 and JP14, please disregard
the above chart - the correct settings
are already built-in to the motherboard.

HardwareCMOS&PasswordReset
If you have been locked out of your system because you forgot your pass-
word or set the CMOS incorrectly, follow the instructions below.
1. Power off the system
2. Set jumper JVBAT1 to pins 2 and 3
3. Wait for 2 seconds, then return
jumper JVBAT1 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.
SoftPowerConnector
The Soft Power Connector is located on pins
1 and 2 of jumper block J5. 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.
SpeakerConnectorInstallation
The Trinity 100AT provides a 4-pin header to
connect the speaker. The speaker is con-
nected to pins 24-27 of jumper block J5.
HardwareResetSwitchConnectorInstallation
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. The Reset switch is a 2-pin connector
and should be installed on pins 22 and 23 of jumper block J5.

CMOSRTC
TheVIAMVP3AGPset includesaRealTime
Clock (RTC) circuit, which provides the date
and time for the system. 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
anew3V lithium battery(Sony CR2032).
FlashEEPROM
The Trinity 100AT uses flash memory to store BIOS programs. It can be easily
updated if necessary using the flash utility (see page 59). Tyan does not
recommend flashing the BIOS unnecessarily. Check theTyan web site for the
latest BIOS revision.
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. 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 aTYAN board though it may work well in a competitor’s

Board Installation
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.
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 2-3
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.
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 2-4 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.
TheTrinity 100ATuses a 64-bit data path from memory to CPU and can
accommodateup to384MBof SDRAM.The168-pin DIMMs (DualIn-line
Memory Modules) must be of the 3.3V, unbufferedvariety. The position of the

notch in the SDRAM key position will tell you whether or not a DIMM is
unbuffered (see the Figure 2-5 below). All installed memory will be automati-
cally detected, so there is no need to set any jumpers.

Somedetails ofmemoryinstallation:
• At least one unbuffered DIMM must be installed for the system to POST.
• Themainboard supports32MB,64MB, 128MB SDRAM.
• PC-100 DIMM is required if CPU bus speed is at 100MHz
• EDO,SDRAM, Parity,and ECC (usingParitymemory) memory issup-
