Introduction
Overview
The S1952DLU Thunder X is a quality, high performance motherboard de-
signed for dual Intel Pentium II Xeon microprocessors. This motherboard
utilizes the Intel 440GXAGPset and can support CPU speeds of 400MHz
through 500MHz, and host bus speeds of up to 100MHz.
The S1952DLU motherboard, with built-inAGPslot, provides high perfor-
mance capabilities that are ideal for a server environment and ideal for a wide
range of demanding applications such as CAD, CAM, CAE, desktop publish-
ing, 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 extendedATX form factor. Some
of the features included are onboard dual channel PCI PIO, Bus Master IDE
and UltraDMA/33, onboard floppy controller, onboard 32-bit PCI Ultra2 dual
channel SCSI, and onboard high speed I/O.
Flexibility and expendability have been designed into the Thunder X.With I/O
and drive controller support built onboard, the oneAGP slot, six PCI and one
ISA slot (one shared, seven usable slots) 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 ofTYAN’s
products along with FAQs, distributors list, drivers, and BIOS setting explana-
tions.
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.

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 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). Please keep in mind that due to the volumes
of emails and technical support calls we receive, our response time may not
necessarily be immediate.
If your dealer is unable to assist you:
1) try our web page: http://www.tyan.com
2) user newsgroup: alt.comp.periphs.mainboard.tyan
3) technical support phone line: [phone]
4)or e-mailaddress: [email protected]

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

2.3 Setting 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. 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.
Quick References for Jumpers
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- CPU Speed Settings (Jumpers JP11, JP12, JP13, JP14)
In order to adjust the speed of the CPU, change the jumper settings according
to the chart below. The clock speed settings control the clock multiplier (CPU
Core / Bus Ratio). 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 component on the system board. See the
motherboard diagram below for jumper locations
CPU Settings for 100MHz Bus
2- CMOS Clear (Jumper JP3)

12 - Reserved Jumpers
The following jumpers are preset for optimum performance. Their settings are
NOT to be changed. Tyan is not responsible for any motherboard malfunc-
tions due to the tampering of these jumper settings. Location of these jumpers
can be found on page 2-4.
JP2 / J14 / J15 / JP21 / JP22 / JP23 - RESERVED!
Soft Power Connector
The Soft Power Connector is located on pins 5 & 6 or pins 6 & 8 of jumper
block JP20. The Thunder X uses the PIIX4e chip 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.
Speaker Connector Installation
The Thunder X provides a 4-pin header to connect the external speaker. The
speaker should be connected to pins 1-4 of jumper JP35. As default, pins 3-4
of jumper JP35 are connected to the internal buzzer.
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. The Reset switch is a 2-pin
connector and should be installed on pins 5 & 7 OR pins 7 & 8 of jumper JP20.
External SMI
TheEXTSMI (External System Management Interface) connector, jumper JP17,
is used by some plug-in cards. Certain applications associated with these
plug-in cards use the interface for hardware control and queries.
