1.4 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. Furthermore, if you purchased your sys-

tem 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:

Chapter 2: Board Installation

2.1 Unpacking

The retail motherboard package should contain the following:

2.2 Installation

You are now ready to install your motherboard. The mounting hole pattern of the Tiger 230 matches the

ATX board specifications, so your chassis must be capable of supporting an ATX board (check the moth-

erboard dimensions provided on p. 5).

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

Question: what’s the first thing I should do?

The first thing you should do is read the user’s manual. It contains important information which will make

configuration and setup much easier, as well as provide information on device installation and component

set up.. By reading through the manual completely before installing your motherboard, you will have a

complete overview on the installation.

Here are some safety tips:

(1) Ground yourself properly before removing your motherboard from the antistatic bag. Unplug

the power from your computer power supply and touch any metal part on the computer case. (You

might also want to wear a grounded wrist strap.)

(2) Hold the motherboard by its edges and do not touch the bottom of the board.

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

(4) Avoid touching pins of memory modules and chips.

(5) Place motherboard on a grounded antistatic surface or on the antistatic bag.

Having reviewed the precautions above, the next step is to take the motherboard out of the cardboard box

and static bag, hold it by its edges, and place it on a grounded antistatic surface, component side up.

Inspect the board for damage.

Press down on any of the socketed 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, unlike physical damage, causes the device to fail over time.

Installation Steps

1. Set jumpers (if necessary)

2. Mount motherboard in chassis

3. Install memory

4. Install CPU and cooling fan(s)

5. Connect IDE and floppy drives

6. Install add-on cards

7. Connect PS/2, USB, and serial devices

NOTE: DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN DAMAGED!

2.4 Quick References for Jumpers

In this manual, the term “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 Figure

2.0a and Figure 2.0c for examples of “on” and “off” pins and jumpers.

Jumpers and pins are connected by slipping the plastic jumper connector over the top 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 2.0b and Figure 2.0d for more examples of 3-pin jumper

connections. NOTE: The small number “1” indicates pin 1.

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. Full page maps of the motherboard can be found on the next two pages.

2.6-J. Soft Power Connector

The soft power connector is part of jumper block J1 (pins 6 to 8). This board uses the chipset for power

management, including turning on and off the system. If the power button function option in the BIOS

Power Management menu is set to “On/Off” (which is the default), pressing the power button once after

the BIOS has booted up will turn the system on and off. If the power button function is set to Suspend,

pressing the power button once will wake up the system or send it to Suspend mode. In this case, you

cannot turn the system off unless you shut down through the Windows operating system or you hold the

power button down for four seconds.

2.6-K. Hardware Reset Switch Connector Installation

The reset switch on your chassis case provides you with the Hardware Reset function, which is the same

as power on/off, except that the system will immediately execute a cold start after the reset button is

pushed.

2.7 Mounting the Motherboard into the Chassis

Your chassis may include mounting hardware. If mounting hardware was included, you can use the fol-

lowing examples to help you in installing your motherboard into the chassis.

The chassis may have come with the studs integrated into the chassis wall, so in those cases you would

only need to use screws (possibly included with your chassis) to install the motherboard. See the exam-

ples (Figure 2.0, shown below) for more details.

If the chassis includes mounting hardware without the studs pre-installed, then you will need to install the

motherboard using the mounting hardware as shown in the examples below. Remember not to over-

tighten any of the screws, or you might risk breaking internal traces in the surrounding area, or damage

the motherboard in some other way.

Other examples of how to install your motherboard using other hardware (that may or may not have been

included with your chassis) are shown below.

2.8 Installing Memory

Please keep in mind that although some memory modules may appear to be high-quality, they may con-

tain inferior or substandard parts. The type of memory you choose to install should be checked against

the memory compatibility list, which is available from Tyan’s website at http://www.tyan.com

Memory Installation Procedure

Here are some details of memory installation for this board:

At least one unbuffered DIMM must be installed for the system to POST.

The motherboard supports 64MB, 128MB, 256MB, and 512MB PC100/133 SDRAM.

All installed memory will be automatically detected, so there is no need to set any jumpers.

The motherboard supports up to 1.5 (3 DIMMs)* or 2 GB (4 DIMMs)* of memory.

Insert the DIMM by pushing the module into the socket with even force. Do not insert one

end and then the other: install the whole module at once or you might bend the DIMM pins.

Make sure the DIMM is securely seated.

Line your module up so that the pins fit into the socket. There is only one way your DIMM can

fit properly. Make sure that the short row of pins is lined up with the short gap in the DIMM

socket.

Lock the DIMM into place by pushing the clips back on either end of the socket onto the

notches in the ends of the DIMM (see pictures below for details).

Step

* 2.0GB total memory @ 4 DIMMs only, when using 100MHz SDRAM

1.5GB total memory @ 3 DIMMs only, when using 133MHz SDRAM

Check the Tyan website for details on memory compatibility: http://www.tyan.com

Tiger 230 S2507 17

Removing a DIMM

Removing a DIMM is just the reverse: simply pull back the clips from the DIMM (see pictures below), and

carefully pull the module straight out. Place the DIMMs in an anti-static bag as soon as you remove them

to avoid static damage.

Suggested Memory Configurations

The table below shows some of the possible memory configurations. Not all possible configurations

are listed. Your memory configuration may differ from one or more of the combinations shown below.

The 168-pin DIMMs (Dual In-line Memory Modules) must be of the 3.3V PC100/PC133 variety. The posi-

tion of the notch in the SDRAM key position will tell you whether or not a DIMM is unbuffered (see Figure

2.1 below). All installed memory will be automatically detected, so there is no need to set any jumpers.

2.9 Installing the CPU and Cooling Fan

Intel Pentium III FC-PGA processors (500 MHz through 1 GHz) or a single FC-PGA type Celeron proces-

sor can be used on this board. For more information on CPU compatibility, check Tyan’s website at:

http://www.tyan.com.

When installing your CPU, remember the following:

The CPU is a sensitive electronic component and can easily be damaged by static electricity

Do not touch the CPU pins with your fingers

You should be able to insert the CPU into the socket with virtually no force

Do not press down hard on the CPU as you might bend or break pins, or otherwise damage the

CPU

The CPU voltage will automatically be detected by the motherboard, so there is no need to set any jump-

ers or BIOS setting.

Installing the Intel Pentium III FC-PGA CPU

Before installing the CPU, check it for any visible damage. Make sure none of the pins are bent or miss-

ing. Be sure where Pin 1 is on both the CPU and the socket. The following steps each have a correspond-

ing picture next to it to help guide you through the installation.

Carefully lift the arm of the ZIF socket until it is at a 90 degree angle

pointing away from the motherboard. Be very careful not to damage

any components that might be next to the socket.

There are two beveled corners on the CPU, which will match the

two angled corners on the socket. Carefully install the CPU by lining

both Pin 1 on the CPU and Pin 1 on the socket, making sure the

pins actually fit into the socket. Do not force the CPU into the

socket: check the pin alignment of CPU pins to socket holes.

Push down lightly on the CPU while lowering the arm on the socket

to secure the CPU (see right). A squeaking noise may be heard

while lowering the arm, or the socket may make a ‘click’ noise when

the arm is locked into position: these noises are normal.

Arm moves down

Pin 1

Step

Tiger 230 S2507 19

Installing the Cooling Fan

After the CPU has been installed, you will need to install the proper cooling device for the CPU. This

device, a heatsink/fan combination, can be purchased at many computer retail stores. Installation of the

cooling device may vary depending on the fan manufacturer’s design. You should also take space into

consideration when install a cooling device: make sure the cooling device is not too big, or else you may

end up damaging components around the CPU socket.

Tyan highly recommends that you use some type of

thermal compound (available from computer retail

stores), between the CPU and heat sink, to maximize dis-

tribution of heat away from the CPU. Please use extra

caution when installing any type of clamp-style fan, or

else damage may occur to the CPU socket, and/or the

CPU itself. See Figure 2.2 (see right) for an example of

how to connect the cooling fan’s power supply. Another

diagram has also been provided below, to aid in CPU fan

installation onto the socket.

Installing Chassis Fans

Alternatively, if you wish to also install chassis fans for increased cooling, we have provided headers to

power those fans as well (see p. 12, section 2.6-D). Chassis fan installation will vary depending on your

chassis manufacturer’s design. Please check with your chassis manufacturer for details on proper chas-

sis fan installation.

2.10 Connecting IDE and Floppy Drives

A variety of IDE and ATAPI-compliant devices* can be

installed on this motherboard, such as hard disk drives

(HDDs) and CD-ROMs.

Please keep in mind that on this motherboard, the primary IDE

connector is BLACK, and the secondary IDE connector is

WHITE. See Figure 2.3 (right) for an example of the IDE cable

properly connected to the motherboard. Consult the documen-

tation that came with your IDE/ATAPI device, or contact the

device’s manufacturer for more details on installation.

Also see Figure 2.4 (right) for an example of the HDD with the

IDE cable installed. Please note that UltraDMA-66 IDE HDDs

require a special 80-wire cable which has additional grounding

wires. This cable has been included with this motherboard for

your convenience. The UltraDMA-66 cable is upwards com-

patible with UltraDMA-100 IDE HDDs, and backwards com-

patible with UltraDMA-33 and legacy IDE HDDs.

NOTE:

The BLUE end of the ATA-66 cable must connect to the motherboard. The black con-

nector on the ATA-66 cable is for the master HDD, and the grey connector is for the

slave HDD. See Figure 2.3 (above) for an example of installation on the mother-

board.

Only Tyan-approved cables are recommended for this motherboard. If you are using

an existing configuration with older cables, your system might not function properly.

Some symptoms of incorrectly installed HDDs are...

May be a Master/Slave configuration problem, bad

IDE cable, or BIOS mis-configuration. Consult the

HDD documentation or contact your HDD vendor.

May be a bad cable or lack of power going to the

drive. Check the cables for damage and bad con-

nections.

Usually means the cable has been installed back-

wards.

Bad IDE cable or defective drives/motherboard. Try

another HDD, or contact your HDD vendor.

Check power cables and cabling. May be a bad

power supply or IDE drive problem.

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 2.5 (below) for an example of a floppy cable. Most of the current floppy drives on the market

require that the cable be installed with the colored stripe positioned next to the power connector. In most

cases, there will be a key pin on the cable which will force a proper connection of the cable.

The first floppy (denoted as A:) is usually attached to the end of the cable with the twist in it. See Figure

2.5 (above) for an example. Drive B: is usually connected to the middle of the cable. Refer to your floppy

drive’s installation instructions, or contact your dealer if you are unsure about how to attach the floppy

drive(s). Remember, you can only have 2 floppy drives connected at any given time.

Some symptoms of incorrectly installed FDDs are...

Usually caused by faulty cables, cables put in back-

wards, or a bad floppy or motherboard. Try another

floppy drive to verify the problem or try another

cable. Also check to see if the onboard floppy is

enabled in the BIOS.

The cable, floppy, or motherboard may be faulty. Try

another cable or floppy drive to verify.

Usually signifies that the cable is on backwards.

Reverse the cable at the floppy drive end and try

again.

Check power cables and cabling. May be a bad

power supply or IDE drive problem.

2.11 Installing Add-on Cards

There are a few rules you need to follow when installing add-on cards. In order to assure proper operation

and a quick installation, adhere to the following guidelines:

If you are going to install a PCI-bus interface card on your system, be aware that any one of the

six 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 motherboard to make

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

NEVER plug an ISA card into a PCI 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, or a rocking

motion between the card and the slot might occur, and could damage the pins within the socket.

Make sure the cards are seated securely into their slots.

Before turning on the system, make sure no cards are touching.

When installing the add-on cards, make sure the cards are installed with even force; do not insert one

end and then the other. See the before (Figure 2.6a) and after (Figure 2.6b) example installation images

below for details.

2.12 Connecting PS/2, USB, and Serial Devices

This motherboard includes ports for PS/2 mouse and keyboard, Universal Serial Bus (USB) devices, and

serial and parallel* devices. Please note that the upper PS/2 port is the mouse port, and the lower PS/2

port is for the keyboard (see Figure 2.7 below).

The PS/2 connectors are probably quite familiar to you, while the USB connectors may not be. A USB

port can function as a serial, parallel, mouse, keyboard, display, or joystick port. It is capable of supporting

up to 127 daisy-chained peripheral devices. All external ports are labeled in Figure 2.7, shown below.

Connecting Serial and Parallel Ports

The serial and parallel ports can be used to connect various devices such as a mouse or printer. The con-

nectors can only be connected one way: be sure and check the orientation of the connector before install-

ing it into the port.

Figure 2.7

NOTE:

When plugging in your keyboard and mouse, or when plugging in anything into a

serial or parallel* 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 sys-

tem and/or external devices that you are trying to install.

INSTALL

http://www.tyan.com

2.13 Connecting the power supply

This motherboard requires an ATX power supply. Tyan recommends using one that conforms to industry

standard Revision 2.01. The images below show the ATX power connector before (Figure 2.8a) and after

(Figure 2.8b) it has been plugged in. The clip on the power connector should lock over the tab on the

onboard connector. You shouldn’t be able to plug the power connector in any other way but just to be

safe, make sure it looks like Figure 2.8b. Make certain that you do not miss connecting any of the pins

because if you do, you will void your warranty and possibly cause damage to yourself and/or your moth-

erboard when the power is turned 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.

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 seem 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 p. 7).

2.14 Frequently Asked Questions (FAQ)

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 conflicts related to the IRQ, or DMA. If

you are using Microsoft Windows, the Control Panel is a good place to start investigating the conflict.

Please consult your operating system documentation for details. Secondly, slowing down the memory tim-

ing in the BIOS’ chipset setup section will help the situation as well. Many memory modules are not suit-

able for high performance systems and are probably the main source of your problem. Also check to

make sure you are using an ATX 2.01 compliant or better power supply. Lastly, make sure the mother-

board is receiving adequete cooling.

Q: I have a question about memory compatibility; what memory will work on my motherboard?

A: Memory compatibility information can be found on Tyan’s website at: http://www.tyan.com

Q: Where can I get additional accessories for my Tyan motherboard?

A: You can purchase additional accessories such as USB cables, as well as other Tyan-approved acces-

sories at the Tyan Computer Online Store: http://www.etyan.com

Q: Where do I get pinout information for my motherboard?

A: Pinouts of certain headers are available on the Tyan website: http://www.tyan.com

Q: My motherboard is dead, how do I return it?

A: Contact the place of purchase or your distributor for assistance to return the motherboard for service.

RMA issues will not be handled via e-mail by Tyan Tech Support. Please refer to the URL link here for

more details: http://www.tyan.com/support/html/rma_faq.html

Q: How do I upgrade my BIOS?

A: Check the section about the Flash Utility (see p.37) for information on upgrading your BIOS. BIOS

update files, flash utilities, and instructions on how to install them are also available from the Tyan website

at: http://www.tyan.com

Q: Why do I get a “CMOS checksum invalid” error message during POST?

A: If you get the above error message or “Invalid configuration, run Setup” message, it is an indication that

the CMOS battery needs to be changed. Contact your dealer for assistance. Once you’ve replaced your

battery, don’t forget to check the Clear CMOS section (see p.12) so that you can reset your CMOS.

Chapter 3: BIOS Setup

Introduction to the BIOS setup

The BIOS is the basic input/output system, required by the computer to perform functions such as CPU

and hard drive support. This chapter describes different settings for Award BIOS that can be used to con-

figure your system.

The BIOS section of the manual is subject to change without notice and is provided here for refer-

ence 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.

The manual describes the Award BIOS setup program. The setup program lets you modify basic configu-

ration 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 Award BIOS 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 sub-

systems.

The BIOS has been customized by adding important, but non-standard, features such as virus and

password protection, power mangement, 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 the Award BIOS setup program.

Starting Setup

The BIOS is immediately activated when you first turn on the computer. The BIOS reads system configu-

ration information in CMOS RAM and begins the process of checking out the system and configuring it

through the Power-On Self Test (POST).

When these preliminaries are finished, the BIOS seeks an operating system on one of the data storage

devices (HDD, FDD, etc.) and if one is found, the BIOS will launch that operating system and hand control

of system operations to it. During POST, you can start the setup program by pressing the [DEL] key when

the “Press DEL key to enter BIOS setup” message appears on the screen.

Tiger 230 S2507 27

Setup Keys

The table below shows how to navigate in the setup program using the keyboard.

Getting Help

Press [F1] to display a small help window that describes the appropriate keys to use and the possible

selections for the highlighted item. To exit the Help Window press [ESC] or the [F1] key again.

In Case of Problems

If you discover that you have trouble booting the computer after making and saving changes with the

BIOS setup program, you can restart the computer by either:

BIOS

http://www.tyan.com

The best advice is to alter only settings that you thoroughly understand. In particular, do not change set-

tings in the Chipset screen unless you are absolutely sure that you need to. The Chipset defaults were

carefully chosen for the best performance and reliability. Even a seemingly small change to the Chipset

setup may cause the system to become unstable.

Setup Variations

Not all systems have the same setup program. While the basic look and function of the setup program

remains more or less the same for all system, the appearance of your Setup screen may differ from other

Award BIOS screens. Each system design and chipset combination require custom configurations. In

addition, the final appearance of the setup program depends on your system designer. You system

designer can decide that certain items should not be available for user configuration, and remove them

from the BIOS setup program.

General Help

At any time, you can press [F1] to bring up a General Help screen in case you want to learn the shortcut

commands. There are two settings you should be aware of (listed below).

3.1 Main Setup

The BIOS allows you to select from several setup functions and two exit choices. If an additional configu-

ration screen is available, it will have a symbol. If you select that option with that symbol, you will be

brought to another configuration screen. Hitting [ESC] will bring you back out.

3.2-C. Table of IDE device settings

The following settings are also available in the Standard CMOS Setup screen.

LBA/Large Mode

Type The type of IDE device installed can be configured using this

option. [Default setting is Auto for auto-detect]

Block (Multi-sector Transfer)

These modules make it possible for the BIOS to take advantage

of the additional space on drives which are larger than 504MB.

This can be auto-detected (when you select Auto for Type), or

you can manually set this mode to Disabled. [Default setting is

Auto]

When set to Auto, the block mode auto-detects the optimal num-

ber of block read/writes per section that the drive supports.

[Default is 0]

PIO Mode

Programming input/output is a method of transmitting data

between devices that use the system’s CPU as part of the data

path. There are 6 modes: 5 with their own transmission speed

and 1 auto mode. To use modes 3 and 4, you must use an

Enhanced IDE drive. [Default is Auto]

DMA Mode

S.M.A.R.T. (Self-Monitoring

Analysis and Reporting Tech-

nology)

This option secifies the Direct Memory Access mode for the IDE

device. If set to Auto, the BIOS will determine the DMA mode.

[Default is Auto]

This option allows the S.M.A.R.T. protocol to report server sys-

tem information over a network. [Default is Auto]

32Bit Data Transfer If set to On, this option allows for the transmission of 32-bits in

parallel (e.g. at the same time). If set to Off, only 16-bits will be

transmitted in parallel. [Default is Enabled]

ARMD Emulation Type Specifies the type of emulation used for a non-disk device

attached as the primary master IDE device. If set to Auto, the

BIOS will determine the emulation type. [Default is Auto]

Drive B

Drive A The settings are 360KB 5.25”, 1.2MB 5.25”, 720KB 3.5”, 1.44MB

3.5”, or 2.88MB 3.5”.

Floppy 3 Mode

The options are the same as listed for Floppy A. [Default setting

is Disabled]

Sets whether you have a Japanese standard mode floppy

(1.2MB storage on 3.5” drive). [Default is Disabled]

Video Sets whether or not the drive can be written to. [Default is Dis-

abled]

3.2-D. Memory

You cannot change any values in the Memory fields, as they are shown only for your information. The

fields show the total installed random access memory (RAM) and amounts allocated to base, extended,

and other memory. RAM is the computer’s working emmory, where the computer stroes programs and

data currently being used, so that they are accessible to the CPU. RAM is counted in kilobytes (KB:

approximately one thousand bytes) and megabytes (MB: approximately one million bytes). Modern per-

sonal computers may contain up to 128, 256 MB, or more.

3.3 Advanced BIOS Features

This section may allow the user to alter certain settings that affect the way their computer boots up,

checks CPU cache, and other advanced features. Please note that you should not alter settings in

this BIOS section unless you are absolutely sure that you know what you are doing.

(continued on next page)

Extended memory

Base Memory Typically 640KB. Also called conventional memory. The DOS

operating system and conventional applications use this area.

Other Memory

Above the 1MB boundary. Early IBM personal computers could

not use memory above 1MB, but current PCs and their software

can use extended memory.

Between 640KB and 1MB; often called high memory. DOS may

load terminate-and-stay (TSR) programs in this area, such as

device drivers, to free as much conventional memory as possi-

ble for applications. Lines in your config.sys file that start with

loadhigh, load programs into high memory, for example.

By checking these items, you will most likely find out what the problem might have been when setting up

your system. For more information on troubleshooting, check the Tyan website at http://www.tyan.com

4.1 Beep Codes

Fatal errors, which halt the boot process, are communicated through a series or audible beeps. For exam-

ple, if the Award BIOS POST can initialize the video but an error occurs, an error message will be dis-

played. If it cannot display video, it will convey a series of beeps.

If you hear one long beep followed by two short beeps, then a video problem has probably occured and

the BIOS is having difficulty initializing the video display. Any other beep sequences that may or may not

occur are probably due to memory problems.

4.2 Displayed Error Messages

If an error occurs after the system display has been initialized, an error message will be displayed as fol-

lows:

ERROR Message Line 1

ERROR Message Line 2

Press <F1> to continue

and the system will halt. Depending on how the Halt On setting was configured in the Standard CMOS

Setup menu, the system may or may not display the error message.

Appendix I: Glossary

ACPI (Advanced Configuration and Power Interface): 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): 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 mem-

ory. While the channel runs at only 66 MHz, it supports data transmission during both the rising and falling

ends of the clock cycle, yielding an effective speed of 133 MHz.

AMR (Audio Modem Riser): a modem that can be used on Intel Reference Motherboard platforms using

Intel’s core logic chipsets supporting AC-link 2.1. It supports fax and all data feedback modes. It provides

high speed communications between your personal computer and a remove lcoation, such as an Internet

Service Provider (ISP).

AT: the original form factor of IBM’s PC.

ATAPI (AT Attachment Packet Interface): also known as IDE or ATA; 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 HDDs.

ATX: the form factor designed to replace the AT form factor. It improves on the AT design by rotating the

board 90 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, USB, serial, 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.

BBS (Bulletin Board System): a computer system with a number of modems hooked up to it which acts a

center for users to post messages and access information.

BIOS (Basic Input/Output System): the program that 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.

Buffer: 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 also the possibility of

losing your data should the system crash. Information stored in a buffer is temporarily stored, not perma-

nently saved.

GLOSSARY

http://www.tyan.com

Bus: 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).

Cache: a temporary storage area for data that will be needed often by an application. Using a cache low-

ers data access times, since the needed information is stored in the SRAM instead of in the slow 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 cache-

able 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 512KB 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 inac-

tive when they are “off” or “open”.

CMOS (Complementary Metal-Oxide Semiconductors): chips that hold the basic startup information for

the BIOS.

COM port: another name for the serial port, which is called as such 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).

DDR (Double Data Rate): improves RAM speed to at least 200 MHz. It activates output on both the rising

and falling edge of the system clock rather than on just the rising edge, potentially doubling output.

DIMM (Dual In-line Memory Module): faster and more capacious form of RAM than SIMMs, and do not

need to be installed in pairs.

DIMM bank: 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 that are similar to IRQs. DMA channels allow hardware devices

(like soundcards 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-

n-Play devices will take care of this for you.

Tiger 230 S2507 43

Doze mode: in this mode, only the CPU’s speed is slowed.

DRAM (Dynamic RAM): widely available, very affordable form of RAM which has the unfortunate ten-

dency to lose data if it is not recharged regularly (every few milliseconds). This refresh requirement

makes DRAM 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. Tyan’s BIOS updates can be found at http://www.tyan.com

ESCD (Extended System Configuration Data): a format for storing information about Plug-n-Play devices

in the system BIOS. This information helps properly configure the system each time it boots.

Fault-tolerance: a term describing a system where one component can quickly be replaced without caus-

ing a loss of service, such as in a RAID system.

Firmware: low-level software that controls the system hardware.

Form factor: an industry term for the size, shape, power supply type, and external connector type of the

Personal Computer Board (PCB) or motherboard. The standard form factors are the AT and ATX,

although Tyan also makes some Baby-AT and ATX Footprint boards.

Global timer: onboard hardware timer, such as the Real-Time Clock (RTC).

Handshaking: 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, a type of fixed drive.

H-SYNC: controls the horizontal synchronization/properties of the monitor.

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

IDE (Integrated Device/Drive Electronics): a simple, self-contained HDD interface. It can handle drives up

to 8.4 GB in size. Almost all IDEs sold now are in fact Enhanced IDEs (EIDEs), with maximum capacity

determined by the hardware controller.

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

GLOSSARY

http://www.tyan.com

I/O (Input/Output): the connection between your computer and another piece of hardware (mouse, key-

board, etc.)

IRQ (Interrupt Request): 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.

Plug-n-Play operating systems can take care of these details for you.

ISA (Industry Standard Architecture): a slower 8- or 16-bit bus (data pathway).

Latency: 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 it waiting for the peripheral to

send some data back (peripherals tend to be slower than onboard system components).

Mirroring: see RAID.

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): Compaq or IBM package other companies’ motherboards

and hardware inside their case and sell them.

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 (Peripheral Component Interconnect): 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).

PCI PIO (PCI Programmable Input/Output) modes: the data transfer modes used by IDE drives. These

modes use the CPU for data transfer (in contrast, 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: 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 pri-

mary 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 pipe-

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

Tiger 230 S2507 45

PM timers (Power Management timers): software timers that count down the number of seconds or min-

utes until the system times out and enters sleep, suspend, or doze mode.

PnP (Plug-n-Play): a design standard that has become ascendant in the industry. Plug-n-Play devices

require little set-up to use. Novice end users can simply plug them into a computer that is running on a

Plug-n-Play aware operating system (such as Windows 98), and go to work. Devices and operating sys-

tems that are not Plug-n-Play require you to reconfigure your system each time you add or change any

part of your hardware.

Striping: see RAID.

RAID (Redundant Array of Independent Disks): a way for the same data to be stored in different places

on many hard drives. By using this method, the data is stored redundantly, also the multiple hard drives

willl appear as a single drive to the operating system. RAID level 0 is is known as striping, where data is

striped (or overlapped) across multiple hard drives, but offers no fault-tolerance. RAID level 1 is known as

mirroring, which stores the data within at least two hard drives, but does not stripe. RAID level 1 also

allows for faster access time and fault-tolerance, since either hard drive can be read at the same time.

RAID level 0+1 is both striping and mirroring, providing fault-tolerance, striping, and faster access all at

the same time.

RAM (Random Access Memory): technically refers 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): a storage chip which contains the BIOS; the basic instructions required to

boot the computer and start up the operating system.

SDRAM (Synchronous Dynamic RAM): called as such 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.

Serial port: called as such 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 Module): formerly the most common form of RAM for motherboards. 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 install SIMM modules. A pair of

SIMM sockets form a SIMM bank, and act as one unit. If only one socket is filled, the bank will not oper-

ate.

Sleep/Suspend mode: in this mode, all devices except the CPU shut down.

GLOSSARY

http://www.tyan.com

SRAM (Static RAM): unlike DRAM, this type of RAM does not need to be refreshed in order to prevent

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

Standby mode: in this mode, the video and fixed disk drive (usually the HDD) shuts down; all other

devices continue to operate normally.

UltraDMA/33/66/100: a fast version of the old DMA channel. UltraDMA is also called UltraATA. Without

the proper UltraDMA controller, your system cannot take advantage of the higher data transmission rates

of the new UltraDMA/UltraATA HDDs.

USB (Universal Serial Bus): 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): the PC video display standard.

V-SYNC: controls the vertical properties of the monitor.

ZIF socket (Zero Insertion Force socket): these sockets make it possible to insert CPUs without damag-

ing the sensitive CPU pins. The CPU is lightly placed in an open ZIF socket, and the metal level is pulled

down. This shifts the processor over and down, guiding it into place on the board.
