Introduction
Overview
The Thunderbolt family is a quality, high performance motherboard designed
for Intel Pentium II and Pentium III microprocessors. This motherboard utilizes
the Intel 440BX or 440GXAGPsets and can support CPU speeds of 233MHz
through 550MHz and host bus speeds of 66MHz to 100MHz (please see
Tyan’s website for up-to-date CPU support information).
The motherboard, with built-inAGPslot, provides high performance capabili-
ties that are ideal for a wide range of demanding applications such as CAD,
CAM, CAE, desktop publishing, 3D animation, and video production.
This integrated high-performance system board is supported in an Extended
ATX form factor. Some of the features included are onboard UltraDMA/33,
onboard dual channel Ultra2 SCSI (Adaptec 7896 chip), onboard Creative
ES1373Audio, onboard Intel Ethernet 82559, and onboard high speed I/O.
With I/O and drive controller support built onboard, the oneAGP slot, six PCI
and one ISA slots (one shared, seven usable) are free for numerous add-on
expansion cards.

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.

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 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,

Installation
You are now ready to install your motherboard. The mounting hole pattern of
the Thunderbolt matches the ATX system board specifications. Your chassis

http://www.tyan.com

should be that of an extended ATX motherboard form factor.
How to install our products right...the first time.
What’sthe firstthingIshould 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 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.
DONOTAPPLYPOWERTOTHEBOARDIFITHASBEEN 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 dis-
charge damage, unlike physical damage, causes the device to fail over time.

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 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 and maps on the following pages will help youset 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. 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 auto-
detects the bus speed of the CPU. PentiumIIIand newer CPUs have their
clockmultiplier preset - asa result, thoseCPUs willignore the S4setting.
Presently all Celeron CPUs use a 66MHz bus speed. Tyan does not recom-
mend 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.

monitored at one time.
1-K. Fan3 Speed Detect (J21) and Fan4 Detect (J22)
J21 and J22 are 2-pin jumpers that control the monitoring of Fan3 or Fan4
respectively. If J21 is set to the ON (closed) position, Fan3 can be monitored
by LANDesk. If set to the OFF (open) position, the Fan will NOT be moni-
tored by LANDesk.
When using Intel’s LANDesk system management software, you may monitor
the status of the CPU Fans by connecting them to the Fan1 and/or Fan2
connectors. You will NOT be able to monitor your CPU fan with the other Fan
connectors.

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 TDAconnector (J10) is for modem audio; the MPEG connector
(J9) is for DVD and TV cards; the VIDEO connector is (J11); the CD connector

Board Installation
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 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 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.
CMOS RTC
The RealTime Clock (RTC) circuit, which provides the date and time for the
system is integrated into the 440BX/GXAGPset. 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
replaceit witha new 3Vlithium 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).
