Introduction
Overview
The Tomcat i815e is a quality, high performance motherboard designed for Socket 370
Type Intel Pentium III / Celeron microprocessors. The Tomcat i815e utilizes the Intel
i815e Chipset with AMI BIOS and can support CPU speeds of 500 MHz through
800 MHz, and host bus speeds of 66MHz to 133MHz. For CPU speed support,
please refer to the CPU Compatibility Chart in Tyan’s website:
http://www.tyan.com/support/html/pentiumii_iii_ppga.html
The Tomcat i815e motherboard, provides high performance capabilities that are ideal
for a wide range of demanding applications such as CAD, CAM, CAE, desktop
publishing, 3D modeling, animation, and video production.
This integrated high-performance system board in an ATX form factor offers more
features and expandability than other ATX boards in its class. Some of the features
included are onboard UltraDMA 66 / 100, onboard digital link sound (optional) and
built-in Intel 3D Graphics accelerator for enhanced graphics performance.
http://www.tyan.com

Flexibility and expandability have been designed into the Tomcat i815e.
With I/O and drive controller support built onboard (along with the many
INTRO
onboard features previously mentioned), the AGP 2x / 4x slot and six PCI slots
are free for more add-on expansion cards.
Remember to take a look at Tyan’s web site located at

http://www.tyan.com. There you can find information on all of Tyan’s products
along with FAQs, distributors list, drivers, and BIOS setting explanations.
Icons
In order to help you navigate this manual and set up your system, we have
added several icons to our format.
This icon alerts you to particularly important details regarding the

! setup or maintenance of your system. This icon often appears next to
important! information that may keep you from damaging your board or system.
While we will often point out the most vital paragraphs in a chapter,
you should always read every word in the text. Failing to do so can
lead to exasperation and expense.
1. Wherever possible, we have included step-by-step instructions for

2.
3. setting up your system, which are indicated by this icon. However, it
procedure
is in your best interest to read an entire section (and perhaps the
entire manual) before you begin to install your motherboard.
While we have alerted you to potential dangers in several places in

warning
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. If a static
safety device is not available to you, remember to touch any un-
painted metal surface in your case before handling your board.

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 in to them to have it serviced, instead of attempt-
ing to do so yourself (which can have expensive consequences).
Help resources:
1. See FAQ and beep codes sections of this manual.
2. See Tyan web site for FAQ, bulletins, driver updates, etc: http://www.tyan.com
3. Contact your dealer or distributor for help BEFORE calling Tyan.
4. Check the Tyan user group: alt.comp.periphs.mainboard.tyan
Returning Merchandise for Service

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

A receipt or copy of your invoice marked with the date of purchase is required before
any warranty service can be rendered. You can obtain service by calling the manufac-
turer 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.

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.
http://www.tyan.com

Here are some precautions you should follow when installing your motherboard:
(1) Ground yourself properly before removing your motherboard

from the antistatic bag. Unplug the power from your computer
and then touch any unpainted metal part on the computer case.
(Or wear a grounded static safety wrist strap.)
(2) Hold the motherboard by its edges and do not touch the bottom of
the board.
INSTALL
(3) Avoid touching motherboard components, IC chips, connectors,
and leads.
(4) Avoid touching pins of memory modules and chips.
(5) Place motherboard on a grounded antistatic surface or on the
antistatic bag.
Having reviewed the precautions above, the next step is to take the motherboard out of
the cardboard box and static bag, hold it by its edges, and place it on a grounded
antistatic surface, component side up. Inspect the board for damage.
! DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN DAMAGED!

important!
Press down on any of the socket ICs if it appears that they are not properly seated
(the board should still be on an antistatic mat). Do not touch the bottom of the board.
Remember, don’t take any electronic device out of its protective bag until you are
ready to actually install it into the computer case. If you do not ground yourself, you
risk zapping the motherboard or adapter card. Subsequent problems may not arise
immediately because electrostatic discharge damage unlike physical damage, causes the
device to fail over time.

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 example of pin connections.

Soft Power Connector
The Soft Power Connector is part of jumper block J15
(pins 6-8). The Tomcat i815e uses the chipset for power
management, including turning on and off the system. If J12
the Power Button Function option in the BIOS Power
Management Menu is set to On/Off (which is the default), pressing the power button
once after the BIOS has booted up will turn the system on and off. If the Power
Button Function option is set to Suspend, pressing the power button once will wake
the system or send it to Suspend mode. In this case, you cannot turn the system off
unless you shut down through the Windows operating system or you hold the power
button down for four seconds.
Hardware Reset Switch Connector Installation

The Reset switch on your case’s display panel provides you with the Hardware Reset
function, which is the same as power on/off. The system will do a cold start after the
Reset button is pushed.
CMOS RTC
The Real Time Clock (RTC) circuit, which provides the date and time for the system is
integrated into the i815e chipset. If the external battery for the RTC is low, it will
prevent your system from POSTing, and you will not get a display. 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 (Sony CR2032).
Flash EEPROM
The Tomcat i815e 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 Writer Utility (see page 50). NOTE: Please be aware that by flashing
your BIOS, you agree that in the event of a BIOS flash failure, you must contact
important!
your dealer for a replacement BIOS. There are no exceptions. Tyan does not
have a policy of replacing BIOS chips directly with end users. In no event will
Tyan be held responsible for damage done to the BIOS by the end user.

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 screws should not short / touch any of the traces on the
motherboard. Make certain that you do not overtighten the screws, as that 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 substan-
dard 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
Figure 2-3
http://www.tyan.com
18
getting the best system available. To make installation easy and trouble free, get high
quality parts. For a list of recommended memory vendors, please visit Tyan’s website
at www.tyan.com - go to the “Memory Support” area in the Support Section. The
website memory compatibility lists include DIMMs that have proven to be very stable
on our boards and perform extremely well.
To install your DIMMs, line your module up so that the pins fit into the slot. There
is only one way that your DIMM can fit properly. Make sure that the short row of
INSTALL
pins is lined up with the short gap in the DIMM slot. Figure 2-3 (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 in 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.
Figure 2-4
Place the DIMMs in an anti-static bag as soon as you remove them to avoid static
damage.

Board Installation
The Tomcat i815e uses a 64-bit data path from memory to CPU and can accommodate
up to 512MB of SDRAM. The 168-pin DIMMs (Dual In-line Memory Modules)
! must be of the 3.3V, unbuffered variety. The position of the notch in the SDRAM
key position will tell you whether or not a DIMM is unbuffered (see the Figure 2-5
important!
below). All installed memory will be automatically detected, so there is no need to set
any jumpers.

Some details of memory installation:
• The mainboard supports 32MB, 64MB, 128MB, and 256MB unbuffered DIMMs.
• There is a limit of two double-sided PC-133 DIMMS that can be installed.
• No ECC type memory can be used.
warning • Warning! DO NOT use registered DIMMs. (Check with your memory dealer

4. Installing the CPU and Cooling Fan
Socket 370 type Pentium III / Celeron processors can be used on the Tomcat i815e.
Remember:
• The CPU is a
sensitive electronic
component and it can
INSTALL
easily be damaged by
static electricity. Do
not touch the CPU
pins with your
fingers.
• Before the CPU is
installed, the
mainboard must be
placed on a flat
surface. You should
be able to insert the
CPU into the socket
with minimal, but firm
pressure. Do not
press down hard on
the CPU.
Figure 2-6*
Pin 1 on the CPU is denoted by a small dot on one of the corners and Pin 1 on the ZIF
socket is denoted by an angled corner (see Figure 2-6). Never force a CPU into a
socket. Forcing a CPU to seat will bend the pins on the CPU and possibly damage the
motherboard.
Push down lightly on the CPU, and lower the arm on the ZIF socket to secure the

5. Connecting IDE and Floppy Drives

The colored stripe on a ribbon cable should face toward the ATX Power Connector on
the motherboard. In Figure 2-8 (below), you can see how the IDE cables should look
when they are connected to your hard drive. Notice how Pin 1 (denoted by a colored
stripe) is connected so that it is next to the power connector of the drive. The primary
IDE connector is black; the secondary IDE connector is white. In most cases, this is
the proper way of connecting your IDE cable to the hard drive. Figure 2-9 on the next
page shows the IDE cable properly connected to the motherboard. Contact your hard
disk drive manufacturer or documentation for more information.
Figure 2-8
ATA-66/100 IDE hard drives require a special 80 pin IDE cable which has additional
grounding wires. The cable is included in the motherboard package, and is required
when using ATA-66/100 drives. This cable will also support all legacy IDE drives.
! (Note: The BLUE end of the ATA-66 cable must connect to the motherboard.)
Some symptoms of incorrectly installed HDDs are:
important!
• 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: usually means bad IDE cable or defective
drives / motherboard. Try another HDD.
• Hard drives do not power up: check power cables and cabling. May also be a bad
power supply or IDE drive.

the actual image of your motherboard.
warning Note: Only Tyan-approved cables will work on this motherboard. If you are
using an existing case with old cables, your system may not function properly.
Use only Tyan-approved cables.
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 2-10 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 always attached to the end of the cable with the twist in it. Drive B: is
always 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 2-10
for a detailed anatomy of the floppy cable.
Remember, you can only have 2 floppy drives connected at any given time.
Some symptoms of incorrectly installed floppy drives 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: normally signifies that the cable is on
backwards. Reverse the cable at the motherboard end and try again.
6. Installing Add-on Cards

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

disable the onboard VGA.
• If you are going to install a soundcard, the
onboard sound must be manually disabled through
the BIOS first.
! • NEVER force a card into a slot. If it doesn’t fit,
look at the socket on the computer to make sure
AGP
slot
important! there are no wires or other obstructions to the slot.
• When plugging the card in, especially when
installing long cards, try to push the entire card in
at one time. Don’t force one end of the card into
the socket first and then the other. This will
create a rocking motion between the card and the slot and it will damage the pins
within the socket.
• Make sure that the cards are seated securely into the slots.
• Before turning on the system, make sure no cards are touching each other.
warning • NOTE: This mother board operates on a 3.3V standby for PCI v2.2.
Because of this, you need to UNPLUG the AC power cord before
installing your card. Otherwise, the motherboard may automatically
power up when the card is inserted into the slot.
http://www.tyan.com
24
If you follow these basic guidelines, there shouldn’t be any problems with installation.
However, if you do encounter any problems, have a qualified professional install your
cards for you or contact your card manufacturer.
Remember, always read the manuals and installation notes that come with the adapter
cards. They contain important information which will help you install the components
right, the first time.

7. Connecting PS/2, USB, Ethernet*, Serial and
Parallel Devices
This board includes ports for USB, Ethernet*, PS/2 mouse, and PS/2 keyboard devices.
Note that, for this board, the mouse port is the upper PS/2 port, and the keyboard port
is the lower PS/2 port.
The PS/2 connectors are probably quite familiar to you, while the Universal Serial Bus
(USB) connectors, may not be. The USB port can function as a serial, parallel, mouse,
keyboard, or joystick port. It is fast enough to support video transfers, and is capable
of supporting up to 127 daisy-chained peripheral devices. Figure 2-11 (below) shows
the ATX double row connectors on this board. The Ethernet*, Serial, and Parallel
ports, as well as the other ports, are labeled.
PS/2 mouse Ethernet* LPT MIDI* / Game Port*

Connecting Serial and Printer Ports

Warning: When plugging in your keyboard and mouse, or when plugging 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 system.

8. Connecting the Power Supply

The Tomcat i815e requires an ATX power supply. Tyan recommends using one that
conforms to industry standard revision 2.01. The photos below show the ATX power
connector before (Figure 2-12) and after (Figure 2-13) it has been plugged in. The
plastic clip on the power connector should lock over the plastic tab on the onboard
connector. You shouldn’t be able to plug the power connector in any other way but
just to be safe, make sure it looks like Figure 2-13 below.
Make certain that you do not miss connecting 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 installing your power supply, make sure the power supply
switch is turned ‘OFF’. You may turn the switch back ‘ON’ once you’ve finished
building your system.
Figure 2-12 Figure 2-13
Ethernet Setup and Use*

Cetain models of the Tomcat i815e motherboards have the optional Intel 82562ET 10/
100 Ethernet controller onboard. For more information, data sheets, white papers, or
demos, visit the Intel Network Products web site at: http://www.intel.com/network
http://www.tyan.com
26
Configuration and Drivers
The Ethernet driver cannot be installed directly from the TYAN Driver CD. Before
installing the Intel 82562 Ethernet drivers, the complete LAN 82562 directory and all
it’s contents must first be copied from the TYAN Driver CD onto your hard drive. The
82562 driver can then be installed from your hard drive.
Connecting the Network Cable

Connect a single network cable to the Ethernet adapter (see Figure 2-14). The cable
INSTALL
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 an 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: To
configure the adapter for your operating system, please refer to your operating
important! system’s documentation.
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).
· Check the LED lights on the adapter. The 100 Mbps LED Link LED
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 Y G
previous page shows their location (see
Figure 2-14).
· Make sure you’re using the correct drivers.

Make sure you’re using the drivers that
come with this adapter.
Figure 2-14
warning · Make sure the hub port and the adapter have the same duplex setting. If you
configured the adapter for full duplex, make sure the hub port is also configured
for full duplex. Setting the wrong duplex mode can degrade performance, cause
data loss, or result in lost connections.

Ethernet Technical Information

Fast Ethernet Wiring
100BASE-TX Specification: The 100BASE-TX specification supports 100Mbps
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 10Mbps. At 100Mbps, 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
100Mbps shared hub, all nodes on the hub must share the 100Mbps 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.
http://www.tyan.com
28
On a shared hub all nodes must operate at the same speed, either 10Mbps or
100Mbps. Fast Ethernet repeaters provide 100Mbps 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
INSTALL
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 100Mbps switching hub, the new station receives its own
dedicated 100Mbps link and doesn’t impact the 100Mbps 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.

Troubleshooting System Problems
If the computer beeps... then...

1, 2, or 3 times... reseat the memory DIMMs or DIPs.
If the system still beeps, replace the
memory.
6 times... try a different keyboard, or replace the
keyboard fuse, if there is one. If the error
occurs again, return the board to your dealer
for a replacement.
8 times... there is a memory error on the video
adapter. Replace the video adapter, or
the RAM on the video adapter (applies only to
external video adapters). If the error occurs
again, return the board to your dealer for a
replacement.
9 times... the BIOS ROM chip is bad. The
system probably needs a new BIOS
ROM chip.
11 times... reseat the cache memory on the
SYSTEM
motherboard. If it still beeps, replace
the cache memory.
4, 5, 7, or 10 times... for 5 or 7 beeps, first test with a new CPU - if that
does not solve the problem, then motherboard must
be replaced.

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, it supports data transmission during both the rising and falling ends of the
clock cycle, yielding an effective speed of 133MHz.
AIMM (AGP Inline Memory Module) is intended to provide 4MB of addressable

SDRAM (arranged as 1Mx32), which resides on a module in a 3.3V or universal AGP
slot.
AMR (Audio Modem Riser) is 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 feeback modes. It provides high speed communicstions
between your perosnal computer and a remote location, such as an Internet Service
Provider (ISP).
AT was the original form factor of IBM’s PC.
ATAPI (AT Attachment Packet Interface), also known as IDE or ATA, is a drive
implementation that includes the disk controller on the device itself. It allows CD-
ROMs and tape drives to be configured as master or slave devices, just like hard drives.
http://www.tyan.com
52
ATX form factor was designed to replace the AT form factor. It improves on the AT
design by rotating the board ninety degrees, so that the IDE connectors are closer to
the drive bays, and the CPU is closer to the power supply and cooling fan. The
keyboard, mouse, serial, USB, and parallel ports are built in.
Bandwidth refers to carrying capacity. The greater the bandwidth, the more data the
bus, phone line, or other electrical path, can carry. Greater bandwidth, then, also results
in greater speed.
A BBS (Bulletin Board System) is a computer system with a number of modems

hooked up to it which acts as a center for users to post messages and access informa-
tion.
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
GLOSSARY
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 applica-
tion. 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.
Communication and Networking Riser (CNR) provides interfaces to support

multichannel audio, V.90 analog modem, telephone line-based home networking, and 10/
100 Ethernet-based networking, as well as expandability for future technologies.
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 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/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.
AGlobal 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 (Industry Standard Architecture) 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 GLOSSARY
part to catch up. This is most common when the system sends data out to a peripheral
device, and is waiting for the peripheral to send some data back (peripherals tend to be
slower than onboard system components).
NVRAM ROM and EEPROM are both examples of Non-Volatile RAM, memory that
holds its data without power. DRAM, in contrast, is volatile.
OEMs (Original Equipment Manufacturers) like Compaq or IBM package other

companies’ motherboards and hardware inside their case and sell them.
The parallel port transmits the bits of a byte on eight different wires at the same time
(that is, in parallel form, eight bits at the same time).
PCI (Peripheral Component Interconnect) 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).

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 98), 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, the basic
instructions required to boot the computer and start up the operating system.
SDRAM (Synchronous Dynamic RAM) is so-called because it can keep two sets of
memory addresses open simultaneously. By transferring data alternately from one set
of addresses, and then the other, SDRAM cuts down on the delays associated with
non-synchronous RAM, which must close one address bank before opening the next.
The serial port is so called because it transmits the eight bits of a byte of data along
one wire, and receives data on another single wire (that is, the data is transmitted in
serial form, one bit after another).
SIMM (Single In-line Memory Modules) are the most common form of RAM. They
must be installed in pairs, and do not have the carrying capacity or the speed of
DIMMs.
http://www.tyan.com
56
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 / 100 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.
USB (Universal Serial Bus) is a versatile port type that 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.
ZIF (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
GLOSSARY
board.
