T echnical 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 you, you can actually bring your system to them to
have it serviced, instead of attempting to do so yourself (which can have
expensive consequences).
If your dealer is unable to assist you,
try our web page, http:// www.tyan.com

Returning Merchandise for Service
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.
For Resellers Only:
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

What’s the first thing I should do?
3.
The first thing you should do is read this user’s manual. It contains important
procedure
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.)
!!

!!
important!
(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!
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.
*Power Supply Requirement: A TX Power Supply should be 2.01 compliant.
Standby curr ent must be 750mA or higher (SB5V = 0.75A)

Quick References for 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

1. Setting Jumpers
1-A. CPU Speed Settings (Switch S4)
There are two steps to set the CPU speed. First, set the clock multiplier with
jumpers S4 according to the specification of your Pentium II CPU using the
chart below. There is no need to set the bus speed. The motherboard autodetects the bus speed of the CPU. Pentium III and newer CPUs have their
clock multiplier preset - as a result, those CPUs will ignore the S4 setting.
Presently all Celeron CPUs use a 66MHz bus speed. Tyan does not recom-

There are four black 4-pin connectors onboard which are used for various
peripherals’ audio signals. The digital signal that comes in through these
connectors is directed through the Ensoniq 1373 PCI sound chip, and the
digital signal is turned into an audio signal which goes out through the
speaker. The TDA connector (J10) is for modem audio; the MPEG connector
(J9) is for DVD and TV cards; the VIDEO connector is (J11); the CD connector

Chapter 2
Board Installation
If you have been locked out of your system because you forgot your password or set the CMOS incorrectly , follow the instructions below .
1. Power off the system
2. Set jumper JP9 to pins 2 and 3 (see page 14 for location of JP9).
3. Wait for at least 2 seconds, then return jumper JP9 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.
Soft Power Connector
The Soft Power Connector is part of jumper block J15. The Thunderbolt uses
the chipset 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 at least four seconds.
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.
CMOS RTC
The Real Time Clock (R TC) circuit, which provides the date and time for the
system is integrated into the 440BX/GX AGPset. If the external battery for the
RTC is low, you will most likely lose your BIOS settings. 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 (CR2032).
Flash EEPROM
The Thunderbolt uses flash memory to store BIOS firmware. It can be updated
as new versions of the BIOS become available. You can upgrade your BIOS
easily using the flash utility (see page 86).

2. Mounting the Motherboard in the Chassis
Follow the instructions provided by the case manufacturer for proper installation guidelines. TYAN recommends that you make use of all mounting holes to
screw down the motherboard. 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.
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 a TYAN board though it may work well in a competitor’s
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. For a list of recommended memory vendors, please visit
T yan’s website at www.tyan.com - go to the “Memory Support” area in the
Support Section. The website memory compatibility lists include DIMMs that
have proven to be very stable on our boards and perform extremely well.

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 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

important!
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 on the next page).
In some cases, pushing the memory module into the DIMM slot will move the
plastic clips inward, automatically locking the module into place. T o remove
your DIMM, simply pull the clips back, and pull up on the module.
Place the DIMMs in an antistatic bag as soon as you remove them to avoid
static damage.

The Thunderbolt uses a 64-bit data path from memory to CPU and can
accommodate up to 2 GB of SDRAM. 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 below). All installed memory will be automatically detected, so there is no need to set any jumpers.

Cache Memory
Celeron processors have the L2 (Level 2) cache built into their architecture, so
there is no need for an L2 cache on the motherboard. The Celeron processor
has a physical L2 cache size of 128KB and a cacheable memory area of 512MB.

4. Installing the CPU and Cooling Fan
Pentium II or Pentium III processors can be used on the Thunderbolt. Please refer
to pages 16-20 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
!!

important!
flat surface. You should be able to insert the CPU with minimal, but
firm, pressure. Do not press down hard on the CPU.
Currently, two types of cooling mechanisms are produced for Pentium II
processors: active (figure 2-6a) and passive (figure 2-6b). These two types of
cooling methods essentially perform the same function. The active cooler is
equipped with a cooling fan and heat sink, while the passive cooler is simply a
larger heat sink with no fan. The type of cooler used has no effect on performance, and both types can be installed in the CPU slot on the Thunderbolt
board.

Installing CPU Retention Modules
Installation of a Pentium II / III processor requires a CPU retention module,
which is first secured onto the motherboard. Tyan offers a variety of retention
mechanisms for the different CPU types. See Appendix 1 for options.
Installation of SECC2 CPUs (Figure 2-7 above) with the retention modules
require a little more attention and care. Instructions for SECC2 CPU installation
can be found on pages 27-32.

Board Installation
T o attach the retention module, place
the motherboard on a flat surface.
Locate the key pin on one end of the
CPU slot on the board. Then carefully
line up the key notch on the retention
module with the key pin on the CPU slot
(the key pin on the CPU slot indicates
the correct orientation of the CPU) See
Figure 2-8.
Drop the retention module (Figure 2-9) down over
the CPU slot so that the retention module sits flat
against the motherboard. Tighten the screws in a
clockwise manner to secure the module to the
board. Warning: Do not overtighten the screws as
Figure 2-9
you may damage the module and/or the motherboard.

Installing the CPU with Active Cooling
When the retention module is securely installed, you are ready
to plug in the CPU. Press down firmly on the CPU until you
hear a “click” (see Figure 2-10). This clicking sound indicates
that the CPU is fully locked into the retention module. If you
have an active cooler, you will also need to connect the CPU’s
cooling fan cable to the cooling fan power connector on the
board.
Locate the cooling fan connector (e.g. F AN1) on the mother board. Plug the CPU’s cooling fan cable into the cooling fan
connector on the board. 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 2-11 on the following page).

Removing the CPU.
T o remove the CPU, move the locks to the center of the CPU. A click will be
heard when the CPU has been unlocked. Gently pull up on the CPU, taking care
not to bend the motherboard or the CPU retention module.
T o remove the lock from the retention module, gently press the ends of the locks
inward and pull.

Installing SECC2 CPUs - Option 1
The major physical difference between regular Pentium II’s and Pentium SECC2 is
the plastic CPU enclosure. As Figure 2-12 indicates, the plastic CPU enclosure
covers the entire CPU card of regular Pentium II’s. On the other hand, the plastic
CPU enclosure covers only the side faces of the SECC2 Pentium II / III card.
Due to the physical differences in the SECC2 CPU, installing the retention
modules requires a different technique than the ones previously discussed.

Currently , the retention module recommended for securing the SECC2 CPU is
included in the motherboard package. The retention braces consist of two
small components that resemble ‘bookends’. (See Figure 2-14 )
The first installation step is to set the retention braces properly against the
sides of the CPU. The lower tabs of the
aluminum heat sink and the bottom Slits
corners of the plastic enclosure should
loosely fit within the two slits of the braces.

Figures 2-15 below show a top view and side view of a retention brace
positioned against one side of the SECC2 CPU.

When both braces are properly positioned, press both braces against the sides
of the CPU and carefully lift them over the CPU slot on the motherboard.
Warning - Because the braces ar e loosely held against the CPU, they can
easily fall off. You must hold both braces against the CPU while lifting all
three components above the motherboard. (See Figure 2-16 on the following
page.)

Be sure to line up the holes of the retention brace with the screws protruding
from the motherboard. At the same time, make sure the CPU is lined up with
the CPU slot. Lower the three components onto the motherboard. The screws
on the motherboard should fit through the holes of the retention braces and
the CPU should fit into the slot. Secure the retention braces with the nuts
provided in the package. The end result should look like Figure 2-17.

When removing the CPU, unscrew the nuts on the retention braces and
remove all three components at once. This may require careful firm tugs to pull
the CPU out of its slot.
