Introduction
Overview
TheS1590S-100 (S1590) Trinity 100ATis a quality, high performance mainboard
designed for Socket 7 microprocessors. This mainboard utilizes the VIA MVP3
100MHz AGPset and can support CPU speeds of 75MHz through 300MHz+
(see specifications section following), and host bus speeds of 66MHz to
100MHz. The Trinity 100AT also has 100MHz Front Side Bus support, which
allows you to take full advantage of 100MHz SDRAM memory 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 integrated system board achieves high reliability with numerous features
and yet is small enough to be supported in an AT 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 the Trinity 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).

ReturningMerchandiseforService
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.
ForResellersOnly:
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.

How to install our products right...the first time.
What’sthefirstthing Ishoulddo?
The first thing you should do is read this user’s manual. It contains important
information which will make configuration and setup much easier.
The next step is to properly ground yourself. First, unplug the power from
your computer case and then touch the metal casing of the power supply or
any metal part on the computer case. This will discharge any electricity from
your body. Take the motherboard out of the cardboard box and static bag,
holding it by its edges, and place it on a grounded anti-static surface, compo-
nent 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 anti-static 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 don’t 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.
Installthemotherboardintoyourcase.
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
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.

The Trinity 100AT has both AT and ATX power supply connectors. The
photos below show the ATX power connector before (Figure 1) and after
(Figure 2) it has been plugged in. The plastic clip on the power connector
should lock over the plastic tab on the onboard connector. You shouldn’t be
