interest to read an entire section (and perhaps the entire manual) before you
begin to fiddle with your motherboard.

While we have alerted you to potential dangers in several places in the
manual with this icon, these warnings should not be regarded as the whole of
your safety regimen. Never forget that computers are electrical devices, and
are capable of delivering a shock. Prevent damage to yourself and to your
board: always ensure that your system is turned off and unplugged whenever
you are working with it, and that you are equipped with a static safety device.

Introduction

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.

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

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

http://www.tyan.com

Returning Merchandise for Service

During the warranty period, contact your distributor or system vendor FIRST for any
product problems. This warranty only covers normal customer use and does not cover
damages incurred during shipping or failure due to the alteration, misuse, abuse, or
improper maintenance of products.

For Resellers Only:

A receipt or copy of your invoice marked with the date of purchase is required before any
warranty service can be rendered. You can obtain service by calling the manufacturer for a
Return Merchandise Authorization (RMA) number. The RMA number should be promi­nently displayed on the outside of the shipping carton and the package should be mailed
prepaid, or hand-carried to the manufacturer. TYAN will pay to have the board shipped
back to you.

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

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.

(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.

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

Quick References for Jumpers

In this manual, the terms closed and on are used when referring to jumpers (or jumper

pins) that are active; open and off are used when referring to jumpers (or jumper pins)
that are inactive. See the Figure 2-1 for examples of on and off pins and jumpers.
The square pin in the diagram is Pin 1.

Jumpers and pins are connected by slipping the blue plastic jumper connector overtop of
two adjacent jumper pins (indicated by 1-2 or 2-3). The metal rod

inside the plastic shell bridges the gap between the two pins, completing the circuit. See
Figure 2-2 for more examples of pin connections.

The tables and maps on the following pages will help you set the jumpers for CPU speed,
Infrared, and external connector pin assignments, among others. The miniature motherboard
maps will help you locate the jumpers on your board. A full-page map of the motherboard can
be found on the next two pages.

Hardware Reset Switch Connector Installation

The Reset switch on your cases display panel provides you with the Hardware Reset
function, which is the same as power on/off. The system will do a cold start after the Reset
button is pushed.

CMOS RTC

The Real Time Clock (RTC) circuit, which provides the date and time for the system is
integrated into the ServerWorks ServerSet III HE chipset. 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 Thunder 2500 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 56).

2. Mounting the Motherboard in the Chassis

Follow the instructions provided by the case manufacturer for proper installation
guidelines. TYAN recommends that you make use of all mounting holes to screw down the
motherboard. The adapter cards and the screws holding them down will keep your board
flat. The fastening screw should not short any of the traces on the motherboard. Make
certain that you do not overtighten the screw, as it will damage the motherboard and
possibly break internal traces in the surrounding area. The hole you should use is located at
the top-center of the board where the adapter cards are fastened to the case.

3. Installing Memory

Since TYAN boards are manufactured with performance in mind, you should use add-in
components that match. Some DIMM modules may seem to be high quality because of
name or feel but that does not guarantee real-world usability. Some cheaper or OEM
memory may have brand-name components, but they may contain inferior or substandard
parts which do not meet the critical tolerances our products require. Because of this, your
memory may not work correctly in a TYAN board though it may work well in a
competitors board. This is because many of our competitors do not adhere to the strict
tolerances required for high performance. If you buy a TYAN board, you are getting the
best system available. To make installation easy and trouble free, get high quality parts.
For a list of recommended memory vendors, please visit 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.

ATTENTION! ONLY REGISTERED DIMMs MAY BE USED ON

THUNDER 2500

Figure 2-3

http://www.tyan.com

18

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 to the previous page 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.

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 below). 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.

Figure 2-4

The Thunder 2500 uses a 64-bit data path from memory to CPU and can accommodate up
to 8 GB of SDRAM. The 168-pin DIMMs (Dual In-line Memory Modules) must be of the

3.3V, buffered variety. The position of the notch in the SDRAM key position will tell
you whether or not a DIMM is buffered (see the Figure 2-5 on the following page). All
installed memory will be automatically detected, so there is no need to set any jumpers.

4. Installing the CPU and Cooling Fan

Pentium II or Pentium III processors can be used on the Thunder 2500. Please refer to pages
14-17 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.

With CPUs reaching much higher clock frequencies, much more effecient cooling methods
must be used to prevent the CPU from overheating. The cooling fan is an important
component that is commonly neglected. Currently, one type of cooling mechanism is
produced for Pentium II / III processors. The active cooler is equipped with a cooling fan
and heatsink, allowing better air flow as well as heat dissipation for the CPU. (See Figure 2­6 below) The type of cooler used has no effect on performance, as long as the CPU fan is
properly connected to the CPU fan header on the motherboard.

your hard disk drive manufacturer or documentation for more 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/mother

Connecting Floppy Drives

Pin 1 on the floppy cable is usually denoted by a red or colored stripe down one side of the
cable (see Figure 2-14 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.

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 2-14 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. Installing Add-on Cards

Thrre are certain 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 PCI slots can support a Master
or Slave device.

!

important!

 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.

 NER 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
u 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.
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.

important!

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.

7. 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.

Figure 2-15 below shows the ATX double row connectors on this board. The Com and
Printer ports, as well as the other ports, are labeled.
Note: Only TYAN 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.

plastic tab on the onboard connector (see Figure 2-17 above).

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 computer is jostled or moved. NOTE: When

Intel Ethernet Setup and Use

The Thunder 2500 S1867 has 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, 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-T 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. 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 (CON6) 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

important!

connector on your motherboard is 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

Thunder 2500 S1867

29

Chapter 2

Board Installation

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.

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 Troubleshoot-

ing section on page 38 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. Make sure that you are following the
proper instructions for your operating system (e.g. if you are using Windows 95 or 98, do

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.
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 95/98 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)

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 capabili
ty. If the full duplex hub provides auto-negotiation, the adapter runs at full duplex. If
the full duplex hub does not provide auto-negotiation, 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.

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.

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.

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.

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 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: My system sometimes has no display. How should I check the system?
A: Check to see if the DIMM is REGISTERED. Also, 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
95/98, 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.

INSTALL

168-pin Registered DIMM

Q: Why dont I get a display after I put in my old DIMM module?
A: The SeverSet HE 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. Make sure
that the DIMM is Registered.

Chapter 2

Board Installation

Q: Can I use EDO DIMMs on this motherboard?
A: No. The ServerWorks ServerSet 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.

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
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 Workstation with the

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

without requiring the installation disks.

INSTALL

39

If you are using the S1867 or are installing with LSI Symbios 53C896 with

53C896 or 53C1010 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.

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.

BIOS Configuration

Introduction to Setup

This manual describes the PhoenixBIOS Setup program. The Setup program lets you
modify basic system configuration settings. The settings are then stored in a dedicated
battery-backed memory, called NVRAM, that retains the information when the power is
turned off.

The PhoenixBIOS in your computer is a customized version of an industry-standard BIOS
for IBM PC ATcompatible personal computers. It supports Intel x86 and compatible
processors. The BIOS provides critical low-level support for the system central processing,
memory, and I/O subsystems.

The Phoenix BIOS has been customized by adding important, but non-standard features
such as virus and password protection, power management, and detailed fine-tuning of the
chipset controlling the system. The rest of this manual is intended to guide you through
the process of configuring your system using Setup.

The BIOS section of the manual is subject to change without

!

notice and is provided here for reference purposes only. The
settings and configurations of the BIOS are current at the time
of print, and therefore they may not be exactly the same as that
displayed on your screen.

BIOS Configuration

Flash Writer Utility

The PhoenixBIOS Flash Writer Utility is now included in the PhoenixBIOS, 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
Phoenixboot.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. Re-poweron the system and it 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 <F2> to run

Setup. You may check your settings at this time, or simply save and exit the program.

Appendix 1

LSI Symbios Ultra2/3 LVD SCSI

1. INTRODUCTION

With the dual channel onboard Ultra2/3 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 or 53C1010 software

The motherboard has two independent Ultra2/3 LVD SCSI channels and each has a
maximum throughput of 80MB/sec or 160MB/sec respectively..

Support for Non-Ultra2/3 SCSI Devices

The LVD signaling used for Ultra2/3 devices operates differently than single-ended
signaling used on Ultra, Fast, and Fast Wide SCSI devices. Ultra2/3 SCSI devices are
designed with multimode capability so that if a single-ended device is connected to the LVD
Ultra2 SCSI bus, the Ultra2/3 devices automatically switch to single-ended mode. When an
Ultra2/3 SCSI device operates in single-ended mode it is subject to the cable distance

limitations and signal noise problems of that interface.

Thunder 2500 S1867

55

SCSI

Appendix 1

LSI Ultra2/3 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 Ultra2/3 devices to operate at full speed

and cable distances.

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-

important!

tion of the software included in the package.

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 peripher-

als between the ends of each cable must have the terminator removed (or disabled).

SCSI

NOTE: When connecting Ultra2/3 SCSI peripherals, it is important to note

!

that the necessary termination of the SCSI bus is done either on the end of

important!

the cable (with a permanent terminator) or a separate terminating connec­ 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
Ultra2/3 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 Ultra2/3 cable or termi
nator before installing the Ultra2/3 SCSI devices.

Thunder 2500 S1867

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 Ultra2/3 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 Ultra2/3 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 Ultra2/3 SCSI channels. Each channel will connect to a
separate cable. Follow these steps to connect your internal peripherals:

!

important!

NOTE: We recommend keeping your Ultra2/3 peripherals separate from your
non-Ultra2/3 peripherals. Connecting a non-Ultra2 peripheral to an Ultra2/3
SCSI bus forces the Ultra2/3 SCSI channel and any attached peripherals to drop
down to Ultra SCSI performance levels (40MBytes/sec).

STEP 1: Locate a 68-pin internal Ultra2/3 SCSI cable. (It should look similar to
the cable below.)

Connect to Motherboard

Connect to Ultra2 Peripherals

Built-in Terminator

STEP 2: Plug the long end of the cable(s) to the Ultra2/3 connector(s) on the
moherboard - Channel A or B. (refer to the board layout for connector
location).

STEP 3: Plug the remaining connectors to your internal Ultra2/3 SCSI peripher
als.

http://www.tyan.com

NOTE: Internal Ultra2/3 SCSI peripherals come from the factory without
termination. Proper termination is provided by the built-in terminator at the

!

important!

end of the Ultra2/3 internal SCSI cable.

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-Ultra2/3 SCSI devices, use a channel
separate from the Ultra2/3 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.

LSI Ultra2/3 LVD SCSI

Connecting the External Cable for SCSI Devices

Use a 68-pin external Ultra2/3 SCSI connector to connect your external Ultra2/3
peripherals. Each Ultra2/3 SCSI peripheral connects to the next in a daisy chain.

Therefore each external peripheral will require an external cable.

As an option, Tyan provides an external Ultra2/3 SCSI connector that can be inserted in
an expansion slot. The cable end of the external SCSI connector can either be plugged
into the Ultra2/3 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 Ultra2/3 SCSI or Ultra SCSI

(and earlier) devices externally. However, mixing both Ultra2/3 SCSI and non­Ultra2/3 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 Ultra2/3
connector at the back of the computer.

High-density 68-pin
External Ultra2/3 SCSI Cable

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.

http://www.tyan.com

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. Ultra2/3 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, the
motherboard is built with the onboard termination Enabled.

ACPI (Advanced Configuration and Power Interface) is a power management specifica-
tion 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 imple-
mentation 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

http://www.tyan.com

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 non­recharged 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. TYANs BIOS updates can be
found at http://www.tyan.com/html/drivers.html

ESCD (Extended System Configuration Data) is a format for storing information 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 compa-

nies 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 non­synchronous 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 33/66 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 (Wake-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.
