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

procedure
What’s the first thing I should do?
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 motherboard:
(1) Ground yourself properly before removing your motherboard
from the 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) Hold the motherboard by its edges and do not touch the bottom of
the board.
(3) A void touching motherboard components, IC chips, connectors,
and leads.
(4) A void 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 place it
on a grounded antistatic surface, component side up. Inspect the board for
damage.
DO NOT APPL Y POWER T O THE BOARD IF IT HAS BEEN DAMAGED!
!!
!
!!
important!
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
2 Pin Jumpers
OFF ON
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.
Figure 2-1
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.

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 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 5 & 7 OR pins 7 & 8 of jumper JP20.
External SMI
The EXTSMI (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.
http://www.tyan.com
2-10
Chassis Intrusion Alarm Connector
The J8 connector is an intrusion alarm, that can be connected to the system
chassis. When active (J8 is connected to the chassis), this alarm will alert the
system administrator anytime someone opens the system’s case.
CMOS RTC
The 440GX AGPsets include a Real Time Clock (R TC) 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 a new 3V lithium battery (Sony CR2032).
Flash EEPROM
The Thunder 100 uses flash memory to store BIOS programs. It can be
updated as new versions of the BIOS become available. You can upgrade your
BIOS easily using the flash utility (see page 3-31).

2.4 Memory Installation
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 use 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.
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. T o make installation easy and trouble free, get high quality parts.
Some brands we recommend are Advantage Memory, Corsair Microsystems,
Millennium, 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.
Figure 2-3
T o 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 set the DIMM into its slot. To insert the DIMM, push
http://www.tyan.com

!!
!
!!
important!
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.
T o 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 below). To remove
your DIMM, simply pull the clips back, and pull up on the module.
INST ALL
Figure 2-4
Place the DIMMs in an antistatic bag as soon as you remove them to avoid
static damage.
The Thunder X uses a 64-bit data path from memory to CPU and can accommodate up to 1024MB of SDRAM (2GB of SDRAM has not been validated).
The 168-pin DIMMs (Dual In-line Memory Modules) must be of the 3.3V ,
unbuffered variety . 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 on the
following page). All installed memory will be automatically detected, so there
is no need to set any jumpers.

Cache Memory
Pentium II Xeon processors have the L2 (Level 2) cache built into their
architecture, so there is no need for an L2 cache on the motherboard. The
Pentium II Xeon processor has a physical L2 cache size of 2MB and a
cacheable memory area of 2MB.
2.5 CPU Installation
Pentium II Xeon processors (400 through 500MHz) can be used on the Thunder
X. Please refer to page 2-4 for the correct CPU jumper settings for your board.
Remember:
• The CPU is a sensitive electronic component and it can easily be damaged
by static electricity. Do not touch the CPU pins with your fingers.
• Before the CPU is installed, the motherboard must be placed on a
flat surface. You should be able to insert the CPU with minimal, but
firm, pressure. Do not press down hard on the CPU.
Currently , Intel produces two types of Pentium II processors: the active (or
boxed) cooling processor and the passive cooling processor (see Figure 2-6
below). These two types of processors are essentially the same in design; the
only difference lies in their cooling methods. The active cooling processor is
equipped with a cooling fan and heat sink, while the passive cooling processor
is equipped with a heat sink alone. Both types of CPUs provide the user with
the same performance, and both types can be installed in the Pentium II slot on
the Thunder X.

Board Installation
First Install the motherboard into your case.
Make sure that your case/chassis is compatible with Intel’s MarlinSpike
MS440GX Slot 2 chassis! Four bolts on the chassis should fit through the
motherboard holes located near the CPU slots (see Figure 2-7 below). Follow
the instructions provided by the case manufacturer for proper installation
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.

Installing CPU Retention Brace
Installation of a Pentium II Xeon processor requires a pair
of CPU retention braces (see Figure 2-8), which is first
secured onto the motherboard.
To attach the retention braces, locate the small retention
brace hole and the bolt hole near the CPU slots on the
board (see Figure 2-7 on previous page). Carefully line up
the pins on the bottom of the brace with the retention
brace holes. At the same time, make sure the chassis bolts
are in line with the bolt holes on the retention brace. There
is only one correct orientation for the modules to be set
properly.
Set the braces in place and fasten them to the bolt using a nut. Tighten the
warning
nut in a clockwise manner to secure the brace to the board. W arning: Do
NOT overtighten as you may damage the retention brace and/or the
motherboard. Your fastened retention braces should look like Figure 2-9
below..

Installing the Processor
Before the CPUs can be
plugged into the slots, you
must attach a handle to each
CPU (See Figure 2-10). The
handles secure the alignment
of the CPUs with each slot and
fasten on top of the retention
brace to lock the CPUs in place.

Figure 2-10
On each side of the handle is a small hook
that fits nicely into the notches on the
sides of the CPU (See Figure 2-11). In order to attach the handle, slide the handle
over the top side of the CPU until the handle
snaps into place (See Figure 2-12)

NOTE: The orientation of the handle to the CPU depends on which slot the CPU
will be inserted to. (See page 2-4 for location of the slots.)
Installing CPU 1
First attach the handle to the top of CPU1. Align the handle so that the screw
holes of the handle are on the OPPOSITE side of the cooling fan or heat sink.
See Figure 2-13.

When the handle is securely installed, you are ready to plug in the CPU. Slide the
CPU between the two retention braces and onto CPU1 slot. Make sure that the
fan or heat sink is facing away from the edge of the motherboard. Press down
firmly on the handle until the CPU is securely in the slot (see Figure 2-14 below).
Be sure to screw the handles onto the retention braces after CPU is inserted.

Installing CPU 2
Attach the handle to the top of CPU 2. Align the handle so that the screw holes
of the handle are on the SAME side of the cooling fan or heat sink. See Figure 215 below.

Figure 2-15
Install CPU2 into the CPU2 slot the same way you installed CPU 1. Again, make
sure that the fan or heat sink is facing away from the edge of the motherboard
(see Figure 2-14 on previous page).
If you have an active cooling processor, you will need to connect the CPU’ s fan
cable to the fan power connector on the board. Locate the fan connector (e.g.
FAN1) on the motherboard. Plug the CPU’s fan cable into the fan connector.
There will be a plastic clip assembly similar to that of the ATX power connector
that will force you to connect the fan cable correctly (see Figure 2-16 below).
