Introduction

Overview

The Thunder 100 family is a quality, high performance motherboard designed
for Intel Pentium II microprocessors. This motherboard utilizes the Intel 440BX
(S1836DLU, S1836DLUAN) or 440GX (S1836DLUAN-GX) AGPsets and can
support CPU speeds of 233MHz through 450MHz, and host bus speeds of
66MHz to 100MHz.

The motherboard, with built-in AGP slot, provides high performance capabili­ties that are ideal for a wide range of demanding applications such as CAD,
CAM, CAE, desktop publishing, 3D animation, and video production.

This integrated system board achieves high reliability with numerous features
and yet is small enough to be supported in an Extended ATX form factor. Some
of the features included are onboard dual channel PCI PIO, Bus Master IDE
and UltraDMA/33, onboard floppy controller, onboard dual channel SCSI,
RAIDport II, onboard Creative Vibra 16XV sound, onboard Intel Ethernet, and
onboard high speed I/O (Ethernet and Sound controllers on DLUAN models
only).

With I/O and drive controller support built onboard, the one AGP slot, six PCI
and one ISA slots (one shared, seven usable) are free for numerous add-on
expansion cards.

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 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).

If your dealer is unable to assist you,

Installation

You are now ready to install your motherboard. The mounting hole pattern of
the Thunder 100 matches the ATX system board specifications. Your chassis

should be that of a standard ATX motherboard form factor.

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

2.

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.

The next step is to properly ground yourself. First, unplug the power from your
computer case and then touch the metal casing of the power supply or any
metal part on the computer case. This will discharge any electricity from your
body. Take the motherboard out of the cardboard box and static bag, holding it
by its edges, and place it on a grounded anti-static surface, component side
up. Inspect the board for damage.

DO NOT APPL Y 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 anti-static 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 install it into the computer case. If you
don’t 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.

Install the motherboard into your case.

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.

Plug in the power connector as shown.

The photos below show the ATX power connector before (Figure 1) and after

(Figure 2) it has been plugged in.

INSTALL

Figure 1

Figure 2

The plastic clip on the power connector should lock over the plastic tab on the

onboard connector. You shouldn’t be able to plug the power connector in any

warning

other way but just to be safe, make sure it looks like Figure 2 above. Make

absolutely 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

computer is jostled or moved. Note: T yan recommends using an ATX power

supply that conforms to industry standard revision 2.01.

Next, connect your IDE cables (if you’re using IDE hard drives).

Figure 3

On all TYAN motherboards, the colored stripe on the cable always faces

towards the rear of the case (towards the ATX connectors).

In Figure 3 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. In most cases,

this is the proper way of

connecting your IDE cable

to the hard drive. Figure 4

information.

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.

Now that you have installed your IDE drives, your floppies are next.

INSTALL

Figure 5

Pin 1 on the floppy cable is usually denoted by a red or colored stripe down
one side of the cable (see Figure 5 above). 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 .

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 5 for a detailed anatomy of the floppy cable. Remember, you
can only have 2 floppy drives connected at any given time.

Chapter 2

Board Installation

On all TYAN motherboards, the colored stripe on the cable always faces
towards the rear of the case (towards the ATX connectors), as with the IDE
cables. Please refer to your documentation for proper installation, or see Figure
4 on page 14.

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 give-away that the cable is on

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

Next are the 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

Note: Only TY AN cables will work on this motherboard. If you are using an

existing case with old cables, your system will not function properly . Use only

TYAN-approved cables.

Connecting the USB and PS/2 ports.

This board includes ports for USB, PS/2 mouse, and PS/2 keyboard devices.

The location of these ports is shown in Figure 6 above. 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. Close-ups of the USB

connector, as well as of the USB and PS/2 ports, are on the following page.

Board Installation

Installing your add-in cards is relatively simple but...

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:

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

be aware that any one of the two 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

each other or are shorting.

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.

Next, you need to install your memory.

Since TY AN 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 TY AN 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. T o make installation easy and trouble free,

http://www.tyan.com

get high quality parts. Some brands we recommend are Advantage Memory ,
Corsair Microsystems, Millenium, Kingston Memory , QesT ec Incorporated,
Unigen, Micron Technology, and Crucial Technology. These DIMMs have
proven to be very stable on our boards and perform extremely well.

Figure 9

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 9
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!

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 10 on the following
page). T o remove your DIMM, simply pull the clips back, and pull up on the
module.

INSTALL

S1836 Thunder 100

Chapter 2

Board Installation

Figure 10

Place the DIMMs in an anti-static bag as soon as you remove them to avoid
static damage.

Finally, install your CPU.

Pentium II processors (233 through 450MHz) can be used on the Thunder 100.
Please refer to pages 28-30 for the correct CPU jumper settings for your board.
Remember:

· The CPU is a sensitive electronic component and it can easily be damaged

!

important!

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. Y ou 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 11) and passive (figure 12). 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 Pentium II slot on the Thunder
100 board.

Figure 1 1 Figure 12

Installing CPU Retention Modules

Installation of a Pentium II 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 details.

T o attach the retention module,
place the motherboard on a flat
surface. Locate the key pin on one
end of the Pentium II slot on the
board. Then carefully line up the
key notch on the retention module
with the key pin on the Pentium II
slot (the key pin on the Pentium II
slot indicates the correct
orientation of the CPU).

Drop the retention module (Figure
14 on the following page) down
over the Pentium II 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 you may damage the
module and/or the motherboard.

Figure 13 - Pentium II Slot Connector
and Key Pin

INSTALL

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 15
on the next page). This clicking sound indicates

S1836 Thunder 100

21

Figure 14

Chapter 2

Board Installation

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 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 A TX power connector that will
force you to connect the fan cable correctly (see Figure 16
below).

Figure 15

Figure 16

Installing the CPU with Passive Cooling

The installation of the CPU with passive cooling differs only slightly from that
of the active. Your passive cooling package should contain one CPU retention
module, one heat sink retention bracket with mounting locks, two mounting
attachments, and one heat sink lock.Install the retention module as explained in
the previous section.

The heat sink mount (Figure 17) has two pins on the bottom and four pins on
the top. Notice that the bottom two pins are of different sizes. The size of the

http://www.tyan.com

22

pins and the holes in the mother­board will determine the correct
orientation. When the bracket is
correctly installed, the four pins
on top will be right next to the

Figure 17

Pentium II CPU slot.

Insert the heat sink mount into the holes on the motherboard. When the
bracket is properly inserted into the holes on the motherboard, you will hear a
clicking noise.

Align the CPU with the CPU retention module. Make sure the heat sink is lined
up with the heat sink mount bracket. If you put the CPU in the wrong way , you
may damage the CPU, the motherboard, and/or the CPU socket. Slowly press
down on the CPU module until the CPU locks into place. Y ou will hear a
clicking noise when the CPU is locked securely into the module.

The heat sink lock (Figure 18) has four
notches which will correspond to the
four pins on the heat sink mounting
bracket. Gently slide the lock between

Figure 18

the heat sink and the heat sink mount­ing bracket until both sides of the lock are firmly secured. A clicking sound will
be heard when the lock is securely fastened to the heat sink mounting bracket.
T o remove the lock from the heat sink mounting
bracket, gently press the ends of the locks inward and
pull.

INSTALL

Lock the heat sink mount to the board by inserting
the two mounting locks (Figure 19) into the pins of
the heat sink mounting bracket which are now below
the mainboard. There will be a click when the locks are
securely fastened.

Figure 19

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.

You are done.

Other than checking the jumper settings and cable connections and putting
the case back on, you are done. Installing a new motherboard may sound
difficult, but by following these directions, you should have a fairly uneventful
time installing our products. If you do encounter problems, your dealer will be
able to help you, or you can consult one of our many technical support
resources (see page 8).

Setting Jumpers

In this manual, the terms “closed” and “on” are used when referring to
jumpers (or jumper pins) that are active; “open” and “off” are used
when referring to jumpers (or jumper pins) that are inactive. Jumpers
and pins are connected by slipping the blue or black plastic jumper
connector overtop of two adjacent jumper pins. The metal rod inside
the plastic shell bridges the gap between the two pins, completing the
circuit. See the drawings below for examples of “on” and “off” pins
and jumpers.

Soft Power Connector

The Soft Power Connector is located on pins 1 and 2 of jumper block J10. The
Thunder 100 uses the PIIX4e chip for power management, including turning on
and off the system. If the Power Button Function option in the Power
Mangement 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 in 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 100 provides a 4-pin header to connect the speaker. The speaker
is connected to pins 24-27 of jumper block J10.

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 22 and 23 of jumper block J10.

External SMI

The EXTSMI (External System Management Interface) connector, JP25, is used
by some plug-in cards. Certain applications associated with these plug-in
cards use the interface for hardware control and queries.

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.

Audio Connectors (S1836DLU only)

There are three 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 Creative Labs Vibra 16XV sound chip, and the digital
signal is turned into an audio signal which goes out through the speaker. JP18
is for modem input/output, JP19 is for Panasonic CD audio, and JP20 is for
Mitsumi CD audio.

procedure

The Thunder 100 uses flash memory to store BIOS programs. It can be updated
as new versions of the BIOS become available. Y ou can upgrade your BIOS
easily using the flash utility (see page 88).

RAM Installation

The Thunder 100 uses a 64-bit data path from memory to CPU and can
accommodate up to 1024MB of SDRAM. The 168-pin DIMMs must be of the

3.3V, unbuffered variety . The position of the notch in the DRAM key position
will tell you whether or not a DIMM is unbuffered (see the figure below).
100MHz SDRAM is recommended. 66MHz SDRAM can also be used only with
CPUs that use a 66MHz bus speed. All installed memory will be automatically
detected, so there is no need to set any jumpers.

Buffered

Unbuffered

168-pin DIMM

Some details of memory installation:

· One unbuffered DIMM must be installed for the system to POST.

· The mainboard supports 8MB, 16MB, 32MB, 64MB, 128MB, and 256MB

SDRAM with SPD, 100MHz or 66MHz SDRAM, and SDRAM+ECC
DIMM modules.

Intel Ethernet Setup and Use

The S1836DLUAN models have the Intel 82558 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/100B adapter (not PRO/100). This information can be
found on Intel’s website, as well as their FTP site and BBS service.

Connect the Network Cable.

Connect a single network cable to the PRO/100B TX PCI adapter . The cable will

procedure

twisted-pair 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-TX Wiring: Twisted Pair Ethernet (TPE). Use category 5 cable and
RJ-45 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. For full duplex, see instructions
on page 13. Note: For more information on 100BASE-TX wiring requirements
and limitations, see “Fast Ethernet Wiring” in this guide and refer to the
README files on the installation disk.

ONBOARD

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

Enable the W ake-on LAN Power Jumper (JP26)

In order for the W ake 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 jumper (JP26) is enabled when the jumper is connected or closed

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.

Using Wake-on LAN

The W ake-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. T ypically this wake-up packet causes the adapter to signal the com­puter to power up and run a pre-defined program.

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 48 for Wake-on LAN trouble­shooting tips.

Configuration and Drivers

The Ethernet driver can not be installed directly from the T yan Driver CD.
Before installing the Intel 82558 Ethernet drivers, the complete LAN 82558

appropriate README file for information on installing your network driver. T o
view the README files, insert the Intel Configuration and Drivers disk into a
drive, switch to that drive, and type: SETUP /README. Look through the
selection called “Installing EtherExpress PRO/100B TX PCI Adapter Drivers”
for the operating system you need.

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.

NetW are 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). While
PROSet can detect all the PRO/100B adapters in your computer, you still need
to perform the configuration process on each adapter. 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)

Duplexing is a performance option that lets you choose how the adapter sends
and receives data packets over the network. The PRO/100B TX adapter can
operate at full duplex only when connected to a full duplex 10BASE-T ,
100BASE-TX switching hub, or another full duplex adapter. T o 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 auto­negotiation, 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 auto-negotiation, the
adapter runs at full duplex. If the full duplex hub does not provide auto­negotiation, you need to set the adapter duplex mode manually (see following
paragraphs)

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

ONBOARD

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.

Manually Configuring for Full Duplex

If your switch supports auto-negotiation with the N-way standard, duplex
configuration is automatic and no action is required on your part. However,
few switches in the current installed base support auto-negotiation. Check
with your network system administrator to verify . Most installations will
require manual configuration to change to full duplex.

Configuration is specific to the driver you’re loading for your network operat­ing system (NOS), as shown in the following paragraphs.

To set up the duplex mode, refer to the section below that corresponds to your
operating system. Adapter performance may suffer or your adapter may not
operate if your hub does not support full duplex and you configure the adapter
to full duplex. Leave the adapter on half duplex if you are not sure what type of
hub you are connected to.

T roubleshooting

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 cross-over
cables.

· Check the LED lights on the adapter. The on-board cable connector has
two diagnostic LEDs. These lights help indicate if there’s a problem with

S1836 Thunder 100

driver filename contains the letter B (for
example, E100BODI.DOS). Drivers that
support previous versions of the

Y

EtherExpress PRO/100 PCI adapter do
not support this version of the adapter.

· Make sure the hub port and the 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.

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 NetW are 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.

ONBOARD

The adapter stopped working when another adapter was added to the
computer.

• Make sure the cable is connected to the EtherExpress PRO/100 TX PCI

adapter.

• Make sure your PCI BIOS is current.

• Make sure the other adapter supports shared interrupts. Also, make sure

your operating system supports shared interrupts — OS/2 doesn’t.

• Try reseating the newest adapter.

The adapter stopped working without apparent cause.

• Try reseating the adapter first, then try a different slot if necessary.

• The network driver files may be corrupt or deleted. Delete and then reinstall

S1836 Thunder 100

the drivers.

• Try a different PRO/100 TX PCI adapter .

• Run the diagnostics.

The Wake-on LAN feature is not working.

• Make sure the WOL cable is attached and power is applied to the computer.

• Check the BIOS for its WOL setting. Some computers may need to be

configured to WOL.

• Make sure the network cable is fully attached to the adapter.

Link LED does not light when power is connected.

• Make sure WOL cable is attached and power is applied to computer.

• Make sure network cable is attached at both ends.

T echnical 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.
Ether-Express PRO/100 TX adapters can be used with either type of
hub for 10 Mbps. At 100 Mbps, a TX hub or switch is required.

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 band-width 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

http://www.tyan.com

48

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 multi-lane 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. Check with your memory vendor for details. The figure
below shows a DIMM module with an SPD EEPROM chip.

EEPROM

RFU

Unbuffered

Buffered

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
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.

ONBOARD

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

for AGP . Some AGP cards require W indows 95 OSR2.1 or a special driver from

S1836 Thunder 100

51

Chapter 3

Onboard Resource Settings

Intel. Please check with your graphics vendor for more details.

Q: How do I install the on-board NIC drivers for W inNT 4.0?
A: The Ethernet driver can not be installed directly from the T yan Driver CD.

Before installing the Intel 82558 Ethernet drivers, the complete 82558 directory
and ALL its components must first be copied from the T yan CD onto your hard
drive. The 82558 installation program can then be copied normally from your
hard drive.

Q: How do I use / enable the RAIDport on the motherboard?
A: All S1836Ds will support the RAIDport as long as the RAIDport card has

BIOS version 3.1 or above. Y ou must also us the ARO-1 130CA driver set
version 3.1. The ARO-1130A is now supported also. It is recommended that
you purchase your RAIDport card from one of Tyan's distributors. Tyan
motherboards have been qualified to use ARO-1130CA or ARO-1 130SA for
best results.

Q: I get a memory test failure or sequencer error when I install the RAIDport
card into the S1836 even though the memory is good.
A: The RAIDport BIOS will report a memory or sequencer failure on the S1836
if you are using RAIDport BIOS version 3.0. Y ou MUST use RAIDport BIOS
version 3.1 for it to work on the S1836.

Q: What RAID levels are supported on the S1836 and RAIDport II card?
A: Currently , RAID levels 0 and 1 are supported on the ARO-1130CA and

RAID 0,1,0/1, and 5 are supported when using the ARO-1130SA.

Q: How can I disable the keyboard detection in the BIOS v .1.12?
A: Y ou 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:

http://www.tyan.com

52

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

2) When you are attempting to create a set of installation disks using the
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: Y ou are using a LS/120-type floppy disk drive.

RESOLUTION - To work around this issue, install W indows NT W orksta
tion with the /b switch. This causes Windows NT Workstation Setup to run
without requiring the installation disks.

If you are using the S1836D or are installing with Adaptec 3940 with AIC­7895 chip then you must install NT 4.0 with a standard 1.44MB floppy disk.

Q: Where can I get Intel PRO/100 + LAN Adapter drivers?
A: You may download the drivers at http://support.intel.com/support/network/

adapter/100PDISK.HTM.

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.

Optimal Defaults

The Optimal default values provide optimum performance settings for all
devices and system features.

Fail-Safe Defaults

The Fail-Safe default settings consist of the safest set of parameters. Use them
if the system is behaving erratically . They should always work but do not
provide optimal system performance characteristics.

Plug and Play A ware 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

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 Y es 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

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, INT A,
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, INT A,
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 .

Language Utility

BIOS

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.

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.

A T API (AT Attachment Packet Interface), also known as IDE or A TA, 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 ATX 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

are built in.

Bandwidth refers to carrying capacity. The greater the bandwidth, the more
data the bus, phone line, or other electrical path, can carry. Greater bandwidth,
then, also results in greater speed.

A BBS (Bulletin Board System) is a computer system with a number of
modems hooked up to it which acts as a center for users to post messages and
access information.

The BIOS (Basic Input/Output System) program resides in the ROM chip, and
provides the basic instructions for controlling your computer’s hardware. Both
the operating system and application software use BIOS routines to ensure
compatibility .

A buffer is a portion of RAM which is used to temporarily store data, usually
from an application, though it is also used when printing, and in most key­board drivers. The CPU can manipulate data in a buffer before copying it, all at
once, to a disk drive. While this improves system performance--reading to or
writing from a disk drive a single time is much faster than doing so repeatedly-­there is the possibility of losing your data should the system crash. Informa­tion stored in a buffer is temporarily stored, not permanently saved.

A bus is a data pathway. The term is used especially to refer to the connection
between the processor and system memory, and between the processor and
PCI or ISA local buses.

Bus mastering allows peripheral devices and IDEs to access the system
memory without going through the CPU (similar to DMA channels).

A cache is a temporary storage area for data that will be needed often by an
application. Using a cache lowers data access times, since the needed informa­tion is stored in the SRAM instead of in the slower DRAM. Note that the
cache is also much smaller than your regular memory: a typical cache size is
512KB, while you may have as much as 1GB of regular memory.

Cache size refers to the physical size of the cache onboard. This should not
be confused with the cacheable area, which is the total amount of memory
which can be scanned by the system in search of data to put into the cache. A
typical setup would be a cache size of 512KB, and a cacheable area of 512MB.
In this case, up to 512MB of the main memory onboard is capable of being

cached. However, only 512KB of this memory will be in the cache at any given
moment. Any main memory above 512MB could never be cached.

Closed and open jumpers Jumpers and jumper pins are active when they are
On or Closed, and inactive when they are Off or Open.

CMOS Complementary Metal-Oxide Semiconductors are chips that hold the
basic start-up information for the BIOS.

The COM port is another name for the serial port, which is so-called because it
transmits the eight bits of a byte of data along one wire, and receives data on
another single wire (that is, the data is transmitted in serial form, one bit after
another). Parallel ports transmit the bits of a byte on eight different wires at the
same time (that is, in parallel form, eight bits at the same time).

DIMM Dual In-line Memory Modules are a faster and more capacious form of
RAM than SIMMs, and do not need to be installed in pairs.

DIMM bank DIMM banks are sometimes called DIMM sockets, because the
physical slot and the logical unit are the same. That is, one DIMM module fits
into one DIMM socket, which is capable of acting as a memory bank.

DMA Direct Memory Access channels are similar to IRQs. DMA channels allow
hardware devices (like sound cards or keyboards) to access the main memory
without involving the CPU. This frees up CPU resources for other tasks. As
with IRQs, it is vital that you do not double up devices on a single line. Plug
and Play devices will take care of this for you.

In Doze mode, only the CPU’s speed is slowed.

DRAM Dynamic RAM is a widely available, very affordable form of RAM
which has the unfortunate tendency to lose data if it is not recharged regularly
(every few milliseconds). This refresh requirement makes DRAM slower three
to ten times slower than non-recharged RAM such as SRAM.

EDO RAM (Extended Data-Out RAM) speeds access to memory locations by
assuming that memory addresses are static: the next time it looks for a bit of
data, it will be at the same spot, or one nearby .

EEPROM Electrically Erasable Programmable ROM, also called Flash BIOS, is a

ROM chip which can, unlike normal ROM, be updated. This allows you to
keep up with changes in the BIOS programs without having to buy a new chip.

ESCD (Extended System Configuration Data) is a format for storing informa-
tion about Plug and Play devices in the system BIOS. This information helps
properly configure the system each time it boots.

Firmware is low level software that controls the system hardware.

Form factor is an industry term for the size, shape, power supply type, and

external connector type of the PCB (personal computer board) or motherboard.
The standard form factors are the AT and ATX, although TYAN also makes
some Baby-AT boards.

A Global timer is an onboard hardware timer, such as the Real Time Clock.

Handshaking is a form of encryption. One system, typically the server, sends
an encryption scheme to another agent, typically a client. Thus, the client’s
data is protected during transmittal to the server.

HDD stands for Hard Disk Drive.

H-SYNC controls the horizontal properties of the monitor.

IC (Integrated Circuit) is the formal name for the computer chip.

IDE Integrated Device (or Drive) Electronics is a simple, self-contained hard

drive interface. It can handle drives up to 8.4GB in size. Almost all IDEs sold
now are in fact Enhanced IDEs (EIDEs).

IDE INT (IDE Interrupt) is a hardware interrupt signal that goes to the IDE.

I/O Input/Output is the connection between your computer and another piece

of hardware (mouse, keyboard, etc.).

IRQ An Interrupt Request is an electronic request that runs from a hardware
device to the CPU. The interrupt controller assigns priorities to incoming
requests and delivers them to the CPU. It is important that there is only one
device hooked up to each IRQ line; doubling up devices on IRQ lines can lock

up your system. Happily, Plug and Play operating systems take care of these
details for you.

ISA stands for Industry Standard Architecture. ISA is a slower 8- or 16-bit BUS
(data pathway).

Latency is the amount of time that one part of a system spends waiting for
another part to catch up. This is most common when the system sends data
out to a peripheral device, and is waiting for the peripheral to send some data
back (peripherals tend to be slower than onboard system components).

NVRAM ROM and EEPROM are both examples of Non-Volatile RAM, memory
that holds its data without power. DRAM, in contrast, is volatile.

OEMs (Original Equipment Manufacturers) like Compaq or IBM package other
companies’ motherboards and hardware inside their case and sell them.

The parallel port transmits the bits of a byte on eight different wires at the
same time (that is, in parallel form, eight bits at the same time).

PCI stands for Peripheral Component Interconnect. PCI is a 32-bit local bus
(data pathway) which is faster than the ISA bus. Local buses are those which
operate within a single system (as opposed to a network bus, which connects
multiple systems).

The PCI PIO (PCI Programmable Input/Output) modes are the data transfer
modes used by IDE drives. These modes use the CPU for data transfer (DMA
channels do not). PCI refers to the type of bus used by these modes to
communicate with the CPU.

PCI-to-PCI bridge allows you to connect multiple PCI devices onto one PCI
slot.

Pipeline burst SRAM is a fast secondary cache. It is used as a secondary
cache because SRAM is slower than SDRAM, but usually larger . Data is
cached first to the faster primary cache, and then, when the primary cache is
full, to the slower secondary cache.

Pipelining improves system performance by allowing the CPU to begin
executing a second instruction before the first is completed. A pipeline can be
likened to an assembly line, with a given part of the pipeline repeatedly

executing a set part of an operation on a series of instructions.

PM timers (Power Management timers) are software timers that count down
the number of seconds or minutes until the system times out and enters sleep,
suspend, or doze mode.

PnP is an acronym for Plug and Play , a design standard that has become
ascendant in the industry. Plug and Play devices require little set-up to use.
Novice end users can simply plug them into a computer that is running on a
Plug and Play-aware operating system (such as Windows 95), and go to work.
Devices and operating systems that are not Plug and Play require you to
reconfigure your system each time you add or change any part of your
hardware.

The term RAM (Random Access Memory), while technically referring to a type
of memory where any byte can be accessed without touching the adjacent
data, is often used to refer to the system’s main memory. This memory is
available to any program running on the computer.

ROM (Read-Only Memory) is a storage chip which contains the BIOS (Basic
Input/Output System), the basic instructions required to boot the computer
and start up the operating system.

SDRAM (Synchronous Dynamic RAM) is so-called because it can keep two
sets of memory addresses open simultaneously. By transferring data alter­nately from one set of addresses, and then the other, SDRAM cuts down on
the delays associated with non-synchronous RAM, which must close one
address bank before opening the next.

The serial port is so called because it transmits the eight bits of a byte of data
along one wire, and receives data on another single wire (that is, the data is
transmitted in serial form, one bit after another).

SIMM Single In-line Memory Modules are the most common form of RAM.
They must be installed in pairs, and do not have the carrying capacity or the
speed of DIMMs.

SIMM bank/socket SIMM sockets are the physical slots into which you stick
SIMM modules. A pair of SIMM sockets form a SIMM bank, and act as a unit.
If only one socket is filled, the bank will not operate.

In Sleep/Suspend mode, all devices except the CPU shut down.

SRAM Static RAM, unlike DRAM, does not need to be refreshed in order to

prevent data loss. Thus, it is faster, and more expensive.

In Standby mode, the video and fixed disk drive shut down; all other devices
operate normally .

UltraDMA/33 is a fast version of the old DMA channel. UltraDMA is also
called UltraATA. Without UltraDMA your system cannot take advantage of
the higher data transmission rates of the new UltraATA hard drives.

Universal Serial Bus or USB, 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.

VGA (Video Graphics Array) is the PC video display standard.

V-SYNC controls the vertical properties of the monitor.

WOL (W ake-on LAN) is a feature which allows remote power up through a

LAN connection when used in conjunction with a WOL compliant network
adapter and appropriate software. The system “listens” to network activity
even when the computer is off. Special “wake-up” packets sent by another
computer causes the adapter to signal the computer to power up and run a pre­defined program.

ZIF socket Zero Insertion Force sockets make it possible to insert CPUs
without damaging the sensitive pins. The CPU is lightly placed in an open ZIF
socket, and the metal lever pulled down. This shifts the processor over and
down, guiding it into place on the board.
