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 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).

Help resources:

1. See FAQ and beep codes sections of this manual.

2. See Tyan web site for FAQ, bulletins, driver updates, etc.

http://www.tyan.com

3. Contact your dealer or distributor for help BEFORE calling Tyan.

4. Check the Tyan user group: alt.comp.periphs.mainboard.tyan

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

Board Installation

How to install our products right...the first time.

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.

2.

3.

procedure

(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) Avoid touching motherboard components, IC chips, connectors,
and leads.

(4) Avoid 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 APPLY POWER TO 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.

*Power Supply Requirement: ATX Power Supply should be 2.01 compliant.
Standby current must be 750mA or higher (SB5V = 0.75A)

1. Setting Jumpers

1-A. CPU Speed Settings (Switch S4)

There are two steps to set the CPU speed. If you have a Pentium II processor,
set the clock multiplier with jumpers S4 according to the specification of your
CPU using the chart below. There is no need to set the bus speed. The
motherboard auto-detects 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 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.

Audio 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 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
(J12) is for CD-ROMs.

*** Plastic Jumper connectors are not provided. Setting is OFF or Enabled
by default.
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 12 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.

http://www.tyan.com

18

CMOS RTC

The Real Time Clock (RTC) 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 84).

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.

INSTALL

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
Tyan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.

To 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

!

shove one end in first; doing so will bend the DIMM pins.

important!

To lock the DIMM into place, push the plastic clips on either end of the slot
onto the notches at 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. To 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.

4. Installing the CPU and Cooling Fan

Pentium II or Pentium III processors can be used on the Thunderbolt. Please refer
to page 14 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.

There two types of cooling mechanisms are produced for Pentium II proces­sors: active (figure 2-6) and passive (figure 2-7). 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.

S1837UANG-L Thunderbolt

Chapter 2

Board Installation

To 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.

Figure 2-8 - Pentium II Slot Connec­tor and Key Pin

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. FAN1) on the mother­board. 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.

To 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.

To 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.

One type of retention module for securing the SECC2 CPU consist of two small
components that resemble bookends. (See Figure 2-14 ) This specific type of
retention may or may not be included in your motherboard package.

The first installation step is to set the
retention braces properly against the sides Slits
of the CPU. The lower tabs of the
aluminum heat sink and the bottom
corners of the plastic enclosure should
loosely fit within the two slits of the braces.

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.

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.

Installing SECC2 CPUs - Option 2

Another method to secure an
SECC2 CPU is by using the
Universal Retention Module
(included in package). The
universal retention module is
designed to accommodate most
versions of the Pentium II / III
CPUs. Included in this solution is
an overhead clip to lock the CPU
into its slot along with the side
universal braces. See Figure 2-18

and secure both braces using
a screw driver.

Next, carefully insert the
CPU between the braces
and onto the CPU slot
(see Figure 2-20). Make
sure the CPU fan faces
towards the center of the
motherboard.

Removing CPU - Removal of the CPU is basically the reverse order of the
installation steps. First remove the overhead clip. You need to push BOTH
side tabs (see Figure 2-22 above) inwards in order to unlock it
from the side braces.

After removing the overhead clip, you need to release the CPU
from the braces one side at a time. Press the center release
tab of one of the side braces (see Figure 2-23 right) while
gently pulling that side of the CPU out of its slot. Repeat the
procedure for the other side brace. When both ends of the
CPU is loose from the side braces and the slot, you will be able
to remove it from the motherboard.

5. Connecting IDE and Floppy Drives

The colored stripe on a ribbon cable should face toward the battery on the
motherboard. In Figure 2-24 below, you can see how the IDE cables should
look when they are connected to your hard drive. Notice how Pin 1 (denoted
by a red stripe) is connected so that it is next to the power connector of the
drive. The primary IDE connector is black; the secondary IDE connector is
white.

Figure 2-24

In most cases, this is the proper way of connecting your IDE cable to the
harddrive. Figure 2-25 on the following page shows the IDE cable properly
connected to the motherboard. Contact your hard disk drive manufacturer or
documentation for more information.

INSTALL

Some symptoms of incorrectly installed HDDs are:

 Hard disk drives are not auto-detected: may be a Master / Slave

problem or a bad IDE cable. Contact your vendor.

 Hard Disk Drive Fail message at bootup: may be a bad cable or lack

of power going to the drive.

 No video or beeps on bootup: usually means the cable is on

backwards.

 Hard drive lights are constantly on: bad IDE cable or defective

drives/motherboard. Try another HDD.

 Hard drives do not power up: check power cables and cabling.

May also be a bad power supply or IDE drive.

Connecting Floppy Drives

Figure 2-25

Pin 1 on the floppy cable is usually denoted by a red or colored stripe down
one side of the cable (see Figure 2-26 below). Most of the current floppy drives
on the market require that the colored stripe be positioned so that it is right
next to the power connector. In most cases, there will be a key pin on the cable
which will force you to connect the cable properly.

Figure 2-26

http://www.tyan.com

Drive A: is usually attached to the end of the cable with the twist in it. Drive B:
is usually connected to the middle of the cable. Refer to your installation
instructions or call your dealer if you are unsure about attaching floppy drives.
Refer to Figure 2-26 for a detailed anatomy of the floppy cable. Remember, you
can only have 2 floppy drives connected at any given time.

The color stripe on the cable should face toward the top of your chassis, or
toward the big white B printed on the motherboard. Please refer to your
documentation for proper installation.

Some symptoms of incorrectly installed floppies are:

 Floppy drives are not detected: usually caused by faulty cables,

backward cables, or a bad floppy or motherboard. Try another single
floppy drive to verify the problem or try another cable. Also, check to
see if the onboard floppy is enabled in the BIOS.

 Floppy Drive Fail message at bootup: the cable, floppy, or

motherboard may be faulty. Try another cable or floppy drive to
verify.

 Light on the floppy is on constantly: a dead giveaway that the cable

is on backwards. Reverse the cable at the motherboard end and try
again.

6. Connecting the Power Supply

Tyan recommends using an ATX power supply that conforms to industry
standard revision 2.01. The Thunderbolt motherboard comes equipped with
two onboard power connectors.

Figure 2-27 on the following page shows an ATX power connector. When
plugging in the power connector, make sure that the plastic clip on the power
connector is aligned with the plastic tab on the onboard connector (see Figure
2-28 on the following page).

INSTALL

Make certain that you do not miss any pins because if you do, you will void
your warranty and cause damage to yourself or your motherboard when you
turn the system on. After connecting the power, make sure the connector is
seated firmly into its socket so it will not become loose or fall off when the

warning

computer is jostled or moved. NOTE: When installing your power supply,
make sure the power supply switch is turned Off. You may turn the switch
back On once youve finished building your system.

7. Installing Add-on Cards

There are a few rules you need to follow when plugging in a card. In order to
assure proper operation and a quick installation, adhere to these guidelines:

!

important!

 If you are going to install a PCI-Bus interface card on your system,

be aware that any one of the PCI slots can support a Master
or Slave device.

 NEVER force a card into a slot. If it doesnt fit, look at the socket

on the computer to make sure there are no wires or other
obstructions to the slot.

 NEVER plug an ISA card into a PCI slot or a PCI card in an ISA

slot. You will void your warranty and damage your system board if
you do this.

 When plugging the card in, especially when installing long cards,

try to push the entire card in at one time. Dont force one end of
the card into the socket first and then the other. This will create a
rocking motion between the card and the slot and it will damage the

pins within the socket.
 Make sure that the cards are seated securely into the slots.
 Before turning on the system, make sure no cards are touching

34

http://www.tyan.com

If you follow these basic guidelines, there shouldnt be any problems with
installation. However, if you do encounter any problems, have a qualified
professional install your cards for you or contact your card manufacturer.

Remember, always read the manuals and installation notes that come with the
adapter cards. They contain important information which will help you install
the components right, the first time.

8. Connecting PS/2, USB, Serial & Parallel Devices

This board includes ports for USB, PS/2 mouse, and PS/2 keyboard devices.
Note that, for this board, the PS/2 mouse port is the upper PS/2 port, and the
PS/2 keyboard port is the lower PS/2 port.

The PS/2 connectors are probably quite familiar to you. The USB connectors,
however, may be foreign. The USB (Universal Serial Bus) is a versatile port.
This one port type can function as a serial, parallel, mouse, keyboard, or
joystick port. It is fast enough to support video transfer, and is capable of
supporting up to 127 daisy-chained peripheral devices.

Connecting Com and Printer Ports

Warning: When plugging in your keyboard and mouse, or when plugging
anything into a serial or Com port, make sure that the power is off. Connecting
these devices and ports while the power is on is called hot plugging, and
may damage your system.

Intel Ethernet Setup and Use

The S1837UANG-L models have the Intel 82559 10/100 Ethernet chip onboard,
which makes setting up your Ethernet connection quite simple. The following
installation and configuration instructions are courtesy of Intel, and the
copyright on the information belongs to Intel Corporation. For more informa­tion, data sheets, white papers, or demos, visit their networking web site at
http://www.intel.com/network.

You can use your modem or Internet connection to download drivers, trouble­shooting tips, and more. When downloading new drivers, make sure the
archive is for the PRO/100+ adapter (not PRO/100). This information can be
found on Intels website, as well as their FTP site and BBS service. You may
find the driver in Tyans CD.

Connect the Network Cable.

Connect a single network cable to the PRO/100+ adapter. The cable will only fit
one way. For 100BASE-TX, your network cable must be category 5, twisted­pair wiring. If you plan on running the adapter at 100 Mbps, it must be
connected to a 100BASE-TX hub (not a 100BASE-T4 hub). For 10BASE-T, use
category 3, 4, or 5 twisted-pair wiring.

100BASE-T Wiring: Twisted Pair Ethernet (TPE). Use category 5 cable and RJ­45 connector for this adapter. Do not use category 3 wiring at 100 Mbps. At
100 Mbps, connect to a TX hub, not a T4 hub. Note: For more information on
100BASE-T wiring requirements and limitations, see Fast Ethernet Wiring in
this guide and refer to the README files on the installation disk.

To configure the adapter, continue with the procedures specific to your
operating system on the pages which follow.

Enable Wake-on LAN Power Jumper (JP34) ­For Add-on Ethernet Cards only

In order for the Wake On LAN (WOL) feature to work correctly, the adapter
must be connected to a continuous power source. This allows the PRO/100+
adapter to listen to the network even when the computer is turned off. The
WOL power connector (JP34) is enabled when the jumper is connected or
closed (ON). Warning: As always, turn off and unplug power to the computer

before setting the WOL jumper. The WOL connector on your motherboard is

impor­tant!

live when the computer is plugged in to a power outlet. Failure to do so could
damage the adapter or computer. Also, be sure that your ATX power supply is

2.01 compliant or better. This level of quality is required because WOL requires
800 mAmps of 5V standby current. Due to power supply requirements, the
ethernet add-on card must have the Intel 82559 Chip for wake-up.

Using Wake-on LAN

In order to use the onboard LAN wake-up feature, you must enable the LAN
Wake-up for Onboard LAN option in the Power Management Setup of the
BIOS. The Wake-on LAN feature operates according to a published specifica­tion. In simple terms, the specification allows designers to build network
adapters that are capable of listening to network activity even when the
computer is turned off. WOL adapters have a special low power standby mode
that is active when the rest of the computer is without power. The adapter will
respond to a special wake-up packet sent by another computer or network
device. Typically this wake-up packet causes the adapter to signal the com­puter to power up and run a predefined program.

INSTALL

The wake up packet structure and behavior is defined in the WOL specifica­tion, available from the website at http://www.us.pc.ibm.com/infobrf/iblan.html.
See the Troubleshooting section on page 45 for Wake-on LAN trouble­shooting tips.

Configuration and Drivers

The Ethernet driver can not be installed directly from the Tyan Driver CD.
Before installing the Intel 82559 Ethernet drivers, the complete LAN 82559
directory and all its contents must first be copied from the Tyan Driver CD
onto your hard drive. The 82559 driver can then be installed from your hard
drive.

Installing Multiple Adapters

All users: The adapters 12-digit, hexadecimal Ethernet address is on a sticker
on the motherboard near the LAN controller chip. The Ethernet address is
sometimes called the node address or the MAC address. Note that the PCI slot
number may not correspond with the physical connector in your computer.
Install only one active WOL adapter per computer. You can install additional,
non-WOL adapters.

NetWare users: The server drivers use the PCI slot number to identify each
installed adapter. You can correlate the PCI slot number to the adapter by
using the Ethernet address that is printed on a label on the adapter. Run Setup
from the Intel disk to view the Ethernet address and slot number for each
installed adapter. For more information, see the README files. NetWare 4.11
server installations use unique slot numbers that are assigned during sever
setup.

Windows NT and Windows 95 users: Repeat the configuration procedure for
each adapter you want to install (add only one adapter at a time). In Windows
NT, be sure to click the Show all PRO Adapters box in the Configuration
window. See the README file for more information.

Select Duplex Mode (optional)

INSTALL

Duplexing is a performance option that lets you choose how the adapter sends
and receives data packets over the network. The PRO/100+ adapter can
operate at full duplex only when connected to a full duplex 10BASE-T,
100BASE-TX switching hub, or another full duplex adapter. To summarize:

 Auto (requires a full duplex adapter or switching hub with auto-negotiation

capability). The adapter negotiates with the hub to send and receive
packets at the highest rate. This is the default setting. If the hub does not
provide auto-negotiation, the adapter runs at half duplex.

 Full duplex (requires a full duplex switching hub or adapter). The adapter

can send and receive packets at the same time. This mode can increase
adapter performance capability. If the full duplex hub provides auto­negotiation, the adapter runs at full duplex. If the full duplex hub does not
provide auto-negotiation, you need to set the adapter duplex mode manu
ally (see following paragraphs)

 Half duplex. The adapter performs one operation at a time; it either sends or

receives.

Note: If your hub is running at 100 Mbps and half duplex, your potential
bandwidth is higher than if you run at 10 Mbps and full duplex.

Push Installation for Windows 95

If you are a LAN Administrator setting up server-based push installation of
Windows 95 as defined in Microsoft Windows 95 Resource Kit, additional

Troubleshooting

If the adapter cant connect to the network:

• Make sure the cable is installed properly. The network cable must be

securely attached at both RJ-45 connections (adapter and hub). If the
cable is attached but the problem persists, try a different cable. The
maximum allowable distance from adapter to hub is 100 meters. If youre
directly connecting two computers (no hub), use a crossover cable. Most
hubs require a straight-through cable, while most switches require a
crossover cable (see your hub or switch documentation to verify). See the
Cabling Information README file for more information on crossover
cables.

• Check the LED lights on the adapter. The onboard cable connector has

two diagnostic LEDs. These lights help indicate if theres a problem with
the connector, cable, or hub. The table below describes the LEDs, and the
drawing on the next page shows their location.

adapter have the same duplex setting. If you configured the adapter for
full duplex, make sure the hub port is also configured for full duplex.
Setting the wrong duplex mode can degrade performance, cause data loss,
or result in lost connections.

Testing the adapter

Test the adapter by running Intel diagnostics. For DOS or Windows 3.1
computers, run Setup on the Intel Drivers and Configuration disk. For Win­dows NT and Windows 95 run Intel PROSet by double-clicking the Intel
PROSet Icon in the Control Panel. Click Help from the main PROSet window to
get complete diagnostics information and instructions.

Common problems and solutions

SETUP.EXE reports the adapter is Not enabled by BIOS.

 The PCI BIOS isnt configuring the adapter correctly.

The computer hangs when the drivers are loaded.

 Change the PCI BIOS interrupt settings.
 If you are using EMM386, it must be version 4.49 or newer (this version

ships with MS-DOS 6.22 or newer).

Diagnostics pass, but the connection fails or errors occur.

 At 100 Mbps use category 5 wiring and make sure the network cable is

securely attached.

 For NetWare clients, make sure you specify the correct frame type in our

NET.CFG file.

 Make sure the duplex mode setting on the adapter matches the setting on

the hub.

 At 100 Mbps, connect to a 100BASE-TX hub only (not T4).

The LNK LED doesnt light.

 Make sure youve loaded the network drivers.
 Check all connections at the adapter and the hub.
 Try another port on the hub.
 Make sure the duplex mode setting on the adapter matches the setting on

the hub.

 Make sure you have the correct type of cable between the adapter and the

hub. 100 BASE-TX requires two pairs. Some hubs require a crossover cable
while others require a straight-through cable. See the Cabling README file
for more information on cabling.

Technical Information

Fast Ethernet Wiring

100BASE-TX Specification: The 100BASE-TX specification supports 100
Mbps transmission over two pairs of category 5 twisted-pair Ethernet (TPE)
wiring. One pair is for transmit operations and the other for receive operations.
Segment lengths are limited to 100 meters with 100BASE-TX for signal timing
reasons. This complies with the EIA 568 wiring standard.

Fast Ethernet Hub and Switches

The two basic types of hubs are shared hubs and switching hubs. Intel PRO/
100+ adapters can be used with either type of hub for 10 Mbps. At 100 Mbps,
a TX hub or switch is required.

S1837UANG-L Thunderbolt

Chapter 2

Board Installation

Shared hubs

In a shared network environment, computers are connected to hubs called
repeaters. All ports of the repeater hub share a fixed amount of bandwidth, or
data capacity. On a 100 Mbps shared hub, all nodes on the hub must share the
100 Mbps of bandwidth. As stations are added to the hub, the effective band­width available to any individual station gets smaller. Shared hubs do not
support full duplex.

Think of a shared repeater hub as a single-lane highway that everyone shares.
As the number of vehicles on the highway increases, the traffic becomes
congested and transit time increases for individual cars.

On a shared hub all nodes must operate at the same speed, either 10 Mbps or
100 Mbps. Fast Ethernet repeaters provide 100 Mbps of available bandwidth,
ten times more than whats available with a 10BASE-T repeater.

Repeaters use a well-established, uncomplicated design, making them highly
cost effective for connecting PCs within a workgroup. These are the most
common type of Ethernet hubs in the installed base.

Switching hubs

In a switched network environment, each port gets a fixed, dedicated amount
of bandwidth. In the highway scenario, each car has its own lane on a multi­lane highway and there is no sharing.
In a switched environment, data is sent only to the port that leads to the
proper destination station. Network bandwidth is not shared among all
stations, and each new station added to the hub gets access to the full
bandwidth of the network.

If a new user is added to a 100 Mbps switching hub, the new station receives
its own dedicated 100 Mbps link and doesnt impact the 100 Mbps bandwidth
of another station. Switching hubs can effectively increase the overall band­width available on the network, significantly improving performance. Switching
hubs can also support full duplex.

Frequently Asked Questions

Q: Why dont I get a display after I put in my old DIMM module?
A: The 440BX/GX chipset requires the memory manufacturer to program an

EEPROM chip with SPD (Serial Presence Detection) on the module in order for
the BIOS to program the chipsets timing registers properly. Your DIMM may
not have the EEPROM chip on the module, or the EEPROM may not contain
the correct program. The figure below shows a DIMM module with an SPD
EEPROM chip. One solution is to change the Method of Memory Detection in
the Advanced Chipset Setup of the BIOS to the Auto Only setting.

INSTALL

EEPROM

168-pin DIMM

Q: My system sometimes becomes unstable. How should I check the system?
A: The first thing to do is to check and see if you have any device conflict in I/

O address, IRQ, or DMA. If you are using Windows 95, the Device Manager is
a good place to start. Please consult your operating system manual for details.
Second of all, slowing down the memory timing in the BIOSs chipset setup
section will help the situation, as well. Many memory modules are not suitable
for high performance systems and are probably the main source of your

S1837UANG-L Thunderbolt

Board Installation

problem.

Q: Can I use EDO DIMMs on this motherboard?
A: No. The Intel 440BX/GX AGPset does not support EDO memory.

Q: What is AGP?
A: AGP (Accelerated Graphics Port) is a new bus architecture for 3D graphics.

The AGP slot eliminates the PCI bandwidth bottleneck by bypassing the PCI
interface and accessing the system memory directly. Currently, the AGP
supports 1X and 2X modes, which yield bandwidths of 266MB/s (at 33MHz
bus speed) and 533MB/s (at 66MHz bus speed), respectively. Compare this
with the mere 132MB/s (at 33MHz bus speed) that you get from the PCI bus.

Q: Does my operating system support AGP?
A: Currently, only Windows 98 and Windows 2000 will have built-in support

for AGP. Some AGP cards require Windows 95 OSR2.1 or a special driver from
Intel. Please check with your graphics vendor for more details.

Q: How do I install the onboard NIC drivers for WinNT 4.0?
A: The Ethernet driver can not be installed directly from the Tyan Driver CD.

Before installing the Intel 82559 Ethernet drivers, the complete 82559 directory
and ALL its components must first be copied from the Tyan CD onto your hard
drive. The 82559 installation program can then be copied normally from your
hard drive.

ONBOARD

Q: How can I disable the keyboard detection in the BIOS?
A: You need to enable the Quick Boot option in CMOS - then the BIOS will not

check for a keyboard.

Q: I cannot install Windows NT when I use an LS/120-type floppy disk drive.
What should I do?
A: SYMPTOM - When you are trying to install Windows NT, you may

experience any of the following symptoms:

1) When you boot from the installation disks, the following error message

may be displayed when disk 2 is inserted:

Stop 0x0000007B Inaccessible Boot Device
(0xFF109C50, 0x00000000, 0x00000000, 0x00000000)

2) When you are attempting to create a set of installation disks using the

http://www.tyan.com

50

WINNT /ox or WINNT32 /ox command, the following error message may be

displayed:

This floppy disk is not formatted as high-density, not formatted
with a standard Windows NT or MS-DOS format, or is corrupted.
Setup is unable to use this disk.

CAUSE OF THE PROBLEM: You are using a LS/120-type floppy disk drive.

RESOLUTION - To work around this issue, install Windows NT Worksta

tion with the /b switch. This causes Windows NT Workstation Setup to run

without requiring the installation disks.

If you are using the S1837D or are installing with Adaptec 3940 with AIC-

7896 chip then you must install NT 4.0 with a standard 1.44MB floppy disk.

Q: Where can I get Intel PRO/100+ Management Adapter drivers?
A: You will find the drivers located in the Tyan Drivers CD under the

subdirectory LAN82559. Please note: You must use the drivers provided

in the Tyan CD only. These drivers have been tested and approved by

Tyan engineering.

Q: Why does my Intel Ethernet work only intermittently?
A: The Inter Ethernet only operates under standby current; therefore, your

power supply must be ATX 2.01 Compliant with a minimum SB5V current of

750mA.

INSTALL

Q: Why does my keyboard LED remain on after the system is turned off?
A: This situation is most likely caused by the enabling of Keyboard Wake-Up

Function (under the Peripheral Setup) in the BIOS. When enabled, the

motherboard would provide a standby voltage to the keyboard. This would

subsequently cause the LED to remain on.

Q: How do I enable the Keyboard Wake-Up function?
A: You will need go into the BIOS and enable the LAN Wake-Up for Onboard

LAN (under the Power Management Setup) and the Keyboard Wake-Up

Function (under the Peripheral Setup). When both functions are enabled,

you can start up your system by hitting the Ctrl key and the F1 key at the

same time. By default both the LAN Wake-Up and Keyboard Wake-Up

functions are disabled.

Auto-Detect Hard Disks

This option lets the system detect your hard disk(s) automatically for your
convenience.

Boot Sector Virus Protection

The available settings for this option are Enable and Disable.

Default Settings

Every option in AMIBIOS Setup contains two default values: a Fail-Safe
default and the Optimal default value. You can also choose to restore the
original BIOS settings (i.e. those that your board came with) at any time.
These options can be found in the Exit menu.

37.5%-50%, 50%-62.5%, 62.5%-75%, or 75-87.5%.

Display Activity

When set to Monitor, this option enables event monitoring on the video
display. If set to Monitor and the computer is in a power saving state, display
activity will cause the system to enter the Full On state. AMIBIOS reloads the
Standby and Suspend time-out timers if display activity occurs. The settings
are Monitor or Ignore.

Device n (Device identity)

When set to Monitor, these options enable event monitoring on the specified
hardware interrupt request line. If set to Monitor and the computer is in a
power saving state, any activity on the IRQ line will cause the system to enter
the Full On state. AMIBIOS reloads the Standby and Suspend time-out timers
if activity occurs on the specified IRQ line. The settings for each of these
options are Monitor or Ignore.

LAN Wake-up

When this option is Enabled, the system will wake up when a signal is received
on the Wake-on LAN header. In order for this wake up function to work, the
system must have been brought up at least past the POST before it was last
shut down (i.e. if you turn the system off before the POST, the registry will not
be set, and the system will not be able to wake up using this function). This
function requires an ATX 2.01 compliant power supply with 5V standby
(STB5V) current of at least 800mA. The settings are Enabled or Disabled.

PC98 Power LED

When this option is Enabled, your power LED will turn to yellow when your
system is in Suspend mode. Note that if you do not have a two-color LED,
your LED will turn off when the system is in Suspend mode if this option is set
to Enabled. The settings are Enabled or Disabled.

FAN OFF at Suspend

If this option is Enabled, the CPU fan will turn off when the system is in
Suspend mode. If Disabled, the CPU fan will remain on while the system is in
Suspend mode. The settings are Enabled or Disabled.

RTC Wake-up

If Enabled, this option allows you to set an hour and minute for the system to
wake up. The next two fields allow you to choose the wake up time. Note that
the time fields will not be available if this option is set to Disabled. In order for
this wake up function to work, the system must have been brought up at least

BIOS Configuration

Plug and Play Aware O/S

Set this option to Yes to inform AMIBIOS that the operating system can
handle plug and Play (PnP) devices. The settings are No or Yes.

PCI Latency Timer (PCI Clocks)

This option specifies the latency timings (in PCI clocks) for PCI devices
installed in the PCI expansion slots. The settings are 32, 64, 96, 128, 160, 192,
224, or 248.

PCI VGA Palette Snoop

When this option is set to Enabled, multiple VGA devices operating on
different buses can handle data from the CPU on each set of palette registers
on every video device. Bit 5 of the command register in the PCI device
configuration space is the VGA Palette Snoop bit (0 is disabled). For example, if
there are two VGA devices in the computer (one PCI and one ISA) and this
field is set for:

.lacitnediebotsecivedhtobfosretsigerettelapehtgnittimrep,sretsigerettelapecivedAGVASIeht

This option must be set to Enabled if any ISA adapter card installed in the
system requires VGA palette snooping.

Allocate IRQ to PCI VGA

Set this option to Yes to allocate an IRQ to the VGA device on the PCI bus.
The settings are Yes or No.

PCI IDE BusMaster

Set this option to Enabled to specify that the IDE controller on the PCI bus has
bus mastering capability. The settings are Disabled or Enabled.

OffBoard PCI IDE Card

This option specifies whether or not an offboard PCI IDE controller adapter
card is used in the computer, and where it is installed. If an offboard PCI IDE
controller is used, the motherboard onboard IDE controller is automatically
disabled. The settings are Auto and Slot1 through Slot6. If Auto is selected,
AMIBIOS automatically determines the correct setting (including using the
onboard controller if no offboard controller card is detected). This option
forces IRQ 14 and 15 to a PCI slot on the PCI local bus. This is necessary to

http://www.tyan.com

support non-compliant PCI IDE adapter cards.

OffBoard PCI IDE Primary IRQ

This option specifies the PCI interrupt used by the primary IDE channel on the
offboard PCI IDE controller. The settings are Disabled, Hardwired, INTA,
INTB, INTC, or INTD.

Offboard PCI IDE Secondary IRQ

This option specifies the PCI interrupt used by the secondary IDE channel on
the offboard PCI IDE controller. The settings are Disabled, Hardwired, INTA,
INTB, INTC, or INTD.

PCI Slot n IRQ Priority

These options specify the IRQ priority for PCI devices installed in the PCI
devices installed in the PCI expansion slots. The settings are Auto, IRQ 3, 4, 5,
7, 9, 10, and 11, in priority order.

DMA Channel n

These options allow you to specify the bus type used by each DMA channel.
The settings are PnP or ISA/EISA .

IRQn

These options specify the bus that the specified IRQ line is used on. These
options allow you to reserve IRQs for legacy ISA adapter cards. These options
determine if AMIBIOS should remove an IRQ from the pool of available IRQs
passed to devices that are configurable by the system BIOS. The available IRQ
pool is determined by reading the ESCD NVRAM. If more IRQs must be
removed from the pool, you can use these options to reserve the IRQ by
assigning an ISA/EISA setting to it. Onboard I/O is configured by AMIBIOS.
All IRQs used by onboard I/O are configured as PCI/PnP. IRQ12 only appears
if the Mouse Support option in Advanced Setup is set to Disabled. IRQ14 and
15 will not be available if the onboard PCI IDE is enabled. If all IRQs are set to
ISA/EISA and IRQ14 and 15 are allocated to the onboard PCI IDE, IRQ9 will
still be available for PCI and PnP devices, because at least one IRQ must be
available for PCI and PnP devices. The settings are ISA/EISA or PCI/PnP.

BIOS

Reserved Memory Size

This option specifies the size of the memory area reserved for legacy ISA
adapter cards. The settings are Disabled, 16K, 32K, or 64K.

S1837UANG-L Thunderbolt

Reserved Memory Address

This option specifies the beginning address (in hex) of the reserved memory
area. The specified ROM memory area is reserved for use by legacy ISA
adapter cards. This option does not appear if the Reserved Memory Size
option is set to Disabled. The settings are C0000, C4000, C8000, CC000, D0000,
D4000, D8000, or DC000.

PCI Device Search Order

This option changes the BIOS scan order of the PCI slot - from first to last or
last to first. The settings are First-Last or Last-First.

BIOS Devnode for Shadow RAM

This option is used for some add-on card ROMs which do not claim the
correct memory range that they occupy. The settings are Disabled or Enabled.

Language Utility

Currently, the BIOS Setup program is available only in English.

Flash Writer Utility

The AMI Flash Writer Utility is now included in the AMIBIOS, and so it is
simpler to upgrade the BIOS of your mainboard. The system BIOS is stored on
a flash EEPROM ROM chip on the mainboard which can be erased and
reprogrammed by following the directions on the following page.

1. From the DOS prompt, rename the BIOS file that you have downloaded to
amiboot.rom and copy it on to a floppy disk.

2. Insert the floppy disk with the BIOS upgrade into the A: drive.

3. Turn the power off.

4. While holding the <Ctrl> and <Home> keys, turn the power on. The system
will begin to read from the A: drive, and write the BIOS information contained
on the floppy disk in that drive to the EEPROM ROM chip. When the BIOS
has been totally reprogrammed, the system will reboot with the new BIOS in
operation.

5. If the system does not reboot in three minutes, power down the system wait
a few seconds, and then turn the power back on again. You will be prompted to
press <F1> to run Setup. You may check your settings at this time, or simply
save and exit the program.

Beep Codes

Fatal errors, which halt the boot process, are communicated through a series of
audible beeps. If AMIBIOS POST can initialize the system video display, it
displays the error message. Displayed error messages, in most cases, allow the
system to continue to boot. Displayed error messages are described on pages
87-88. See the top of the next page for the beep code chart.

DIMMs. If the system still beeps, replace
the memory.

6 times... reseat the keyboard controller chip. If

it still beeps, replace the keyboard
controller. If it still beeps, try a
different keyboard, or replace the
keyboard fuse, if there is one.

8 times... there is a memory error on the video

adapter. Replace the video adapter, or
the RAM on the video adapter.

9 times... the BIOS ROM chip is bad. The

system probably needs a new BIOS
ROM chip.

11 times... reseat the cache memory on the

motherboard. If it still beeps, replace
the cache memory.

4, 5, 7, or 10 times... the motherboard must be replaced.

CPU Retention Module Options

Tyan offers two different options for securing Intels Pentium II and Celeron
CPUs onto the motherboard. Each option provides retention for both older
Pentium IIs as well as newer Pentium IIs (including Slot 1 type Celeron).

OPTION 1:

Two different types of retention modules are included in the motherboard
package. For older versions of Pentium II, use the retention module shown in
Figure 1. For newer versions of Pentium II CPUs (including Slot 1 type Celeron
and SECC2 CPUs), use the retention module shown in Figure 2. (Screws for

LSI Symbios Ultra2 LVD SCSI

1. INTRODUCTION

With the dual channel onboard Ultra2 SCSI connectors, you can connect up to
30 SCSI peripherals, such as hard disk drives, scanners, CD-ROM drives, and
tape drives. This guide provides instructions for

 Connecting SCSI peripherals
 Installing the Symbios 53C896 software

The motherboard has two independent Ultra2 LVD SCSI channels and each
has a maximum throughput of 80MBytes/sec.

Support for Non-Ultra2 SCSI Devices

The LVD signaling used for Ultra2 devices operates differently than single­ended signaling used on Ultra, Fast, and Fast Wide SCSI devices. Ultra2 SCSI
devices are designed with multimode capability so that if a single-ended device
is connected to the LVD Ultra2 SCSI bus, the Ultra2 devices automatically
switch to single-ended mode. When an Ultra2 SCSI device operates in single­ended mode it is subject to the cable distance limitations and signal noise
problems of that interface.

Appendix 2

LSI Ultra2 LVD SCSI

LSI recommends that single-ended Ultra and earlier devices be kept on a
separate channel than the LVD Ultra2 devices. This will permit the Ultra2
devices to operate at full speed and cable distances. The motherboard has a
standard narrow SCSI (50-pin) connector to simplify connecting single-ended
devices. Please refer to jumper J29 for further settings.

2. Setting Up SCSI Peripherals

Setting up SCSI peripherals before attaching them to the SCSI connectors
typically involves setting SCSI IDs and termination, mounting internal
peripherals inside your computer, and connecting power cables to each
peripheral. Since setup can vary from peripheral to peripheral, always refer to
the peripherals documentation for specific instructions. Below are some
guidelines for setting SCSI IDs and termination on your peripherals.

NOTE: If you refer to the peripherals documentation for installation

!

instructions, be sure to return to this document to continue with installa­ tion of the software included in the package.

important!

Check the SCSI IDs

The motherboard SCSI connectors and each peripheral you connect to it
requires a unique SCSI ID number ranging from 0 to 15 on each channel. ID
numbers dont have to be sequential, as long as the connector and each
peripheral has a different number for each channel.

Each SCSI channel on the motherboard is preset to ID 7 and should not be
changed. If you will be booting from a SCSI hard disk, its best to set the
disks ID at 0 or 1. Most SCSI hard disks come from the factory preset to ID 0.
The IDs for internal peripherals are usually set with jumpers; external peripher­als are usually set with a switch on the back of the peripheral.

Terminate the Ends

To ensure reliable communication on the SCSI bus, the peripheral at the end of
each cable, or the end of the cable itself, must have a terminator installed (or
enabled). The peripherals between the ends of each cable must have the
terminator removed (or disabled).

NOTE: When connecting Ultra2 SCSI peripherals, it is important to note

!

that the necessary termination of the SCSI bus is done either on the end of
the cable (with a permanent terminator) or a separate terminating connec-

important!

tor. Ultra SCSI and earlier single-ended devices had the ability to terminate
the bus directly from the device. Using an Ultra SCSI terminator on an LVD
Ultra2 SCSI bus will force the bus to single-ended mode, limiting the speed
and cable distance. For this reason be sure that you have the necessary
Ultra2 cable or terminator before installing the Ultra2 SCSI devices.

3. Connecting SCSI Peripherals

A total of 30 SCSI peripherals can be connected to the onboard SCSI connec­tor, with 15 on each channel. Before connecting peripherals to the connectors,
be sure to also review Setting Up SCSI Peripherals on the previous page.

Connecting Internal Cables for Ultra2 SCSI Devices

When connecting internal Ultra2 SCSI peripherals there are special SCSI cables
necessary to sustain the higher speeds of LVD signaling. If your cables are
not marked, you can identify most Ultra2 SCSI cables as having twisted pairs
of the flat ribbon cable in between the device connectors. These cables will
usually have a terminator built into the end of the cable.

The motherboard has two separate Ultra2 SCSI channels. Each channel will
connect to a separate cable. Follow these steps to connect your internal
peripherals:

NOTE: We recommend keeping your Ultra2 peripherals separate from your
non-Ultra2 peripherals. Connecting a non-Ultra2 peripheral to an Ultra2

drop down to Ultra SCSI performance levels (40 MBytes/sec).

STEP 1: Locate a 68-pin internal Ultra2 SCSI cable. (It should look similar
to the cable below.)

STEP 2: Plug the long end of the cable(s) to the Ultra2 connector(s) on the
motherboard - Channel A or B. (refer to the board layout for connector
location).

STEP 3: Plug the remaining connectors to your internal Ultra2 SCSI
peripherals.

NOTE: Internal Ultra2 SCSI peripherals come from the factory without
termination. Proper termination is provided by the built-in terminator at the

end of the Ultra2 internal SCSI cable.

important!

Connecting Internal Cables for Non-Ultra2 SCSI Devices

Internal cables for single-ended SCSI devices do not have special twists or
terminators built into the cable ends. If you are connecting non-Ultra2 SCSI
devices, use a channel separate from the Ultra2 SCSI devices you just con­nected. The motherboard has a special 50-pin narrow connector to more easily
support narrow Ultra and earlier devices if you so choose.

If you are connecting Wide SCSI peripherals you will need a 68-pin cable. If
you are connecting narrow SCSI peripherals you will need a 50-pin cable.
When connecting the 50-pin cable to peripherals ensure that the colored edge
of the cable connects to pin 1 of both the device and the motherboard SCSI
connector.

STEP 1: Locate a 68-pin or 50-pin internal Ultra SCSI cable.

STEP 2: Plug the long end of the cable to the 68-pin motherboard connec­ tor if the cable is 68-pin or plug the long end of the cable to the 50-pin
motherboard connector if the cable is 50-pin.

STEP 3: Plug the other end of the cable to a terminated Fast/Wide Ultra
SCSI peripheral (if 68-pin) or a terminated Fast/Ultra Narrow SCSI peripheral
(if 50-pin).

STEP 4: To connect a second peripheral, plug the middle connector of the
cable to the peripheral. The peripheral must not be terminated.

Connecting the External Cable for SCSI Devices

Use a 68-pin external Ultra2 SCSI connector to connect your external Ultra2
peripherals. Each Ultra2 SCSI peripheral connects to the next in a daisy chain.
Therefore each external peripheral will require an external cable.

An external Ultra2 SCSI connector can be inserted in an expansion slot. The
cable end of the external SCSI connector can either be plugged into the Ultra2
SCSI motherboard connector, or it can be connected to the end of a 68-pin
Ultra SCSI cable (be sure to take off the cable terminator first).

NOTE: You have the option to connect either Ultra2 SCSI or Ultra SCSI
(and earlier) devices externally. However, mixing both Ultra2 SCSI and non­ Ultra2 SCSI on the same channel will cause all devices on that channel to

!

operate in Ultra SCSI (single-ended) mode with the limits of the cable and

speeds of that interface.

STEP 1: Connect one end of an external SCSI cable to the external Ultra2
connector at the back of the computer.

STEP 2: Connect the other end of the cable to a SCSI connector on the

back of an external peripheral. If you are installing only one external
peripheral, terminate the peripheral and skip to Step 4.

STEP 3: Connect other external peripherals by connecting each peripheral
to the previous one until all peripherals are connected. The peripheral at
the end of the chain must be the only external peripheral terminated.

Terminate SCSI

STEP 4: Connect all power cables to the external peripherals.

4. Additional Termination Information

The last physical device on the end of each SCSI bus cable must be termi­nated. Termination must be disabled for all other devices in the middle of the
cables. Ultra2 SCSI peripherals do not have built-in termination, but Ultra and
Fast/Wide devices do have termination that must be checked. For more
information refer to the owners manuals for each SCSI device.

The host adapter will automatically enable or disable termination as necessary.

When installed in multiple computer configurations, i.e. clusters, you can force
the motherboard to enable termination even when power to the computer is
OFF. This would enable the other computers in the cluster to continue to
operate the shared SCSI devices even when the computer

supplying termination at the other end of the bus is shut down. By default,

Glossary

ACPI (Advanced Configuration and Power Interface) is a power management
specification that allows the operating system to control the amount of power
distributed to the computers devices. Devices not in use can be turned off,
reducing unnecessary power expenditure.

AGP (Accelerated Graphics Port) is a PCI-based interface which was designed
specifically for demands of 3D graphics applications. The 32-bit AGP channel
directly links the graphics controller to the main memory. While the channel
runs at only 66MHz, 2X supports data transmission during both the rising and
falling ends of the clock cycle, yielding an effective speed of 133MHz.

The AT was the original form factor of IBMs PC.

ATAPI (AT Attachment Packet Interface), also known as IDE or ATA, is a drive
implementation that includes the disk controller on the device itself. It allows
CD-ROMs and tape drives to be configured as master or slave devices, just
like hard drives.

The AT X form factor was designed to replace the AT form factor. It improves
on the AT design by rotating the board ninety degrees, so that the IDE
connectors are closer to the drive bays, and the CPU is closer to the power
supply and cooling fan. The keyboard, mouse, serial, USB, and parallel ports
