Chapter 2: Board Installation

WARNING: The Thunder i7500 only supports

EPS12V power supplies and will not operate with
other types. Refer to section 2.12 for instructions on

installing EPS12V power supplies. DO NOT use
ATX 2.x, ATX12V and dual AMD power supplies as

they will damage the board and void your warranty.
Only EEB V3.0 form factor chassis is supported.

Other form factors may short the board because the
installation studs are in different locations than
ones required by the Thunder i7500.

Installation

You are now ready to install your motherboard. The mounting hole pattern of the Thunder i7500
matches the SSI system board specifications. Your chassis should support a standard SSI
motherboard form factor.

How to install our products right…the first time

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 take when
installing your motherboard:

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

Unplug the power from your computer power supply and then touch the power supply.

For the safest conditions, TYAN recommends wearing a static safety wrist strap.
(2) Hold the motherboard by its edges and do not touch the bottom of the board.
(3) Avoid touching the motherboard components, IC chips, connectors, and leads.
(4) Avoid touching memory module contacts and IC chips
(5) Place the motherboard on a grounded antistatic surface or on the antistatic bag from

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.

The following pages will detail for you on how to install your motherboard into your chassis, install
processor(s), memory, hard drive and floppy cables/drives and heatsinks.

2.5 – PCI Setup

PCI slots A1, A2, B1 and B2 are all PCI -X slots while PCI slot C is a conventional 32-bit/33MHz
PCI slot. However, PCI slots A1, A2, B1 and B2 will operate at the speed of the slowest PCI card
that is installed into them. If a 33MHz PCI card is inserted into bus A, both A slots will operate at
33MHz. The same rule applies for Bus B slots. A1 and A2 are BUS-A and B1 and B2 are BUS-

B.
PCI Slot (1) B1: PCI-X 66MHz

- Onboard SCSI (optional) and LAN (optional) utilizes this slot’s resources

- 3.3 volt cards accepted

PCI Slot (2) B2: PCI-X 66MHz

- Onboard SCSI (optional) and LAN (optional) utilizes this slot’s resources

- Supports Adaptec Zero -Channel RAID (Nighthawk)

- 3.3 volt cards accepted

PCI Slot (3) A1: PCI -X 133/100/66MHz
Will operate at the PCI-X capability of the card you insert.
PCI Slot (4) A2: PCI -X 133/100/66MHz
Will operate at the PCI-X capability of the card you insert.
PCI Slot (5) C1: PCI 32 -bit/33MHz

- 5 and 3.3 volt cards accepted (3.3V only card can not be plugged in)

Bus A, B and C are independent of each other and do not share the same resources
B1 Slot supports 1U (M2037) and 2U (M2041) riser cards. Both are available at:

2.6 – Mounting the Motherboard

Before installing your motherboard, make sure your chassis has the necessary motherboard
support studs installed. These studs are usually metal and are gold colored. Usually, the chassis
manufacturer will preinstall the support studs in SSI EEB v3.0 form factor. If you’re not sure which
stud goes where, simply lay the motherboard inside the chassis, aligning the screw holes of the
motherboard to the studs inside the case. If there are any studs missing, you’ll know right away
since the motherboard will not be able to be securely installed.

Some chassis include plastic studs instead of metal ones. These ones are also usable but TYAN
recommends using metal studs with screws to make sure the motherboard does not get jarred
during shipping or lots of movement.

Below is a chart detailing what the most common motherboard studs look like and how they
should be installed.

TIP: Use metal studs if possible, as they hold the motherboard into place more securely than
plastic standoffs.

13

http://www.TYAN.com

2.7 – Installing the Memory

Before attempting to install any type of memory, make sure that the memory you have is
compatible with the motherboard as well as the processor. The Thunder i7500 supports the use of
PC2100 DDR memory. However, the Intel E7500 chipset specifications will only allow memory to
operate at PC1600. You may use either PC2100 and or PC1600. Critically important is whether
you’re using the recommended memory for the current board you have. For this information,
please check TYAN’s website at: www.tyan.com

The following diagram shows the types of RAM modules you may encounter depending on your
board:

14

http://www.TYAN.com

Memory Installation Procedure
The Thunder i7500 requires that memory modules be installed in pairs. Please refer to the

next page for exact details on installing memory modules correctly.

When you install the memory modules, make sure the module aligns properly with the memory
socket. There should be keys (small indents) on your memory modules that fit according to the
keys in the memory socket. DDR SDRAM modules and sockets have only one key, which is
slightly near the center of the module/socket. SDR SDRAM (also just referred to as PC100 or
PC133) and their sockets have two keys and will not insert into DDR DIMM slots. The method of
installing memory modules are detailed by the following diagrams.

Once the memory modules are firmly seated in the socket, two clamps on either side will close
and secure the module into the socket. Sometimes you may need to close the clamps yourself.

To remove the memory module, simply push the clamps outwards until the memory module pops
up. Then, remove the module.

TIP: When you’re installing memory, it may require a considerable amount of force to push the
modules into their socket. To avoid bending and damaging your motherboard, place it on its anti­static bag and onto a flat surface, and then proceed to install the memory modules. This way you’ll
avoid motherboard damage even if you use too much force.

NOTE

YOU MUST unplug the power connector to the motherboard before performing

system hardware changes, to avoid having your motherboard boot-up
automatically, due to the PCI v2.2 spec.

15

http://www.TYAN.com

Memory Pair Installation

You must install the first two memory modules in DIMM A1
and DIMM B1.

Both modules must be the same in both size and density. Modules must also use the same chip
configuration, as in each module that is installed must physically have the same number of
memory chips on them.

All memory sockets must be populated by the same memory type, either x4 modules or x8
modules. You cannot mix and match x4 and x8 modules together. The Thunder i7500 will not
support any other type of memory configuration.

A few things to remember:

• At least TWO Registered DDR SDRAM modules must be installed

for the system to turn on and POST (power on self test) and
DIMM modules must be installed in pairs.

• Use ONLY x8 or x4 type memory modules. Mixing memory types
affects sta bility.

• When installing modules, install them in this order: A1, B1, A2,
B2, etc.

• 128MB, 256MB, 512MB, 1GB, and 2GB Registered
PC2100/PC1600 DDR SDRAM memory modules are supported
in x4 or x8 configuration.

• The Thunder i7500 supports up to 12GB of memory

2.8 – Installing the Processor(s) & Heatsinks

Your brand new Thunder i7500 supports the latest processor technologies from Intel. Check the
following page on TYAN’s website for latest processor support:

http://www .Tyan.com

The following diagrams will detail how to install your processor(s):

The CPU Voltage Mismatch (LED) – Refer to D11 on page 8 and page 11.

REMINDER

The processors you choose to use may not look exactly like the one pictured above, nor will the
socket look exactly the same. For example, your processor may appear to be in a different color
and have different markings on it. The diagram is provided as a visual guide to help you install
socket processors.

1. Lift the lever on the socket until it is approximately 130o or as far back as possible

2. Align the processor with the socket. There are keys underneath the processor just like

3. Seat the processor firmly into the socket by gently pressing down until the processor

4. Place the socket lever back down until it snaps into place.

5. Your processor is installed.

6. Repeat these steps for the second processor if you are using two processors.

Take care when installing Xeon processors as they have very fragile connector pins below
the processor and can bend and break if inserted improperly.

Heatsink Installation

After you are done installing the processor(s), you should proceed to installing their heatsinks.
Heatsinks will ensure that the processors do not overheat and continue to operate at maximum
performance for as long as you own them. Overheated processors are dangerous to the health of
the motherboard.

Because there are many different types of heatsinks available from many different manufacturers,
a lot of them have their own method of installation. For the safest method of installation and
information on choosing the appropriate heatsink, please refer to Intel’s certified heatsinks
webpage at the following Internet address:

Will light up red if there is a mismatch in CPU voltage. Only identical CPUs can
be used.

When installing only 1 processor, ensure to install it in CPU socket 1.

17

http://www.TYAN.com

The following diagram will illustrate how to install the most common heatsinks:

1) Align the heatsink mounting bracket to the holes around the processor socket

2) Insert Black securing peg into bracket holes

18

http://www.TYAN.com

3) Insert White locking peg into Black securing peg

4) Repeat process to mount all other brackets

5) Seat heatsink between brackets on the processor

6) Attach heatsink clips

NOTE

Currently the default Intel Retail wind tunnel cover that installs on top of the
heatsink will NOT fit on the Thunder i7500.

19

http://www.TYAN.com

Finishing Installing the Heatsink

After you finish installing the heatsink onto the processor and socket, attach the end wire of the
fan (which should already be attached to the heatsink) to the motherboard. The following diagram
illustrates how to connect fans onto the motherboard.

After you’re finished installing all the fans you can connect your drives (hard drives, CD-ROM
drives, etc.) to your motherboard.

2.9 – Attaching Drive Cables

Attaching IDE cables to your drives is simple because they only go in one way. TYAN
motherboards have two on-board IDE channels for you to use, each supporting two drives. There
is a white and a black IDE connector on your motherboard. The black connector is the Primary

IDE channel and the white connector is the Secondary IDE channel.

Attaching IDE cables to the IDE connectors is illustrated below:

Simply plug in the BLUE END of the IDE cable into the motherboard IDE connector, and the other
ends into the drive(s). Each standard IDE cable has three connectors, two being close to each
other. The BLUE connector that is far on its own is the end that plugs into the motherboard
whereas the other two connectors are used to connect to drives.

TIP: Pin 1 on the IDE cable (usually denoted by a colored wire) faces the drive’s power
connector.

20

http://www.TYAN.com

Floppy Drives

Attaching floppy diskette drives are done in a similar manner to hard drives. See the picture 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 that will force a proper connection of the cable.

The first floppy drive (sometimes denoted as
A:) is usually attached to the end of the cable
with the twist in it. Drive B: is usually connected
to the second or third connector in the cable
(the second or third connector after you install
Drive A:).

Refer to your floppy drive’s installation
instructions (if available), 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.

Below are some symptoms of incorrectly installed floppy drives. While they are minor and
installing them incorrectly doesn’t cause severe problems, it may cause your system to freeze or
crash when trying to read and or write to disks.

Symptoms of incorrectly installed floppy drives

Drive is not automatically detected

Drive Fail message at bootup

Drive does not power on

Drive activity light is constantly on

Usually caused by faulty cables, cables put in
backwards or a bad floppy drive or
motherboard. Try another floppy drive to verify
the problem if the cable is properly installed or
try replacing the actual cable. Also check to
see if the onboard floppy controller is enabled
in the BIOS setup.
The cable, floppy drive or motherboard may be
faulty. Try another drive or cable to verify.
Check power cable and cabling. Maybe a bad
power supply or drive cable problem.
Usually signifies that the cable on the drive is
on backwards, which is a common issue.
Reverse the cable at the floppy drive end and
try again.

2.10 – Installing Add-In Cards

Before installing add-in cards, it’s good to be aware if they’re fully compatible with your
motherboard. For this reason, we’ve provided a chart, listing the most common slots that may
appear on your motherboard. Not all the slots in this diagram will be on the same board though,
but there will be combinations. See below for the way the slots look and what each one means.

Simply find the appropriate slot for your expansion card and insert the card firmly. Do not force
any expansion cards (or anything else) into any slots if they refuse to go in. It is better to try
another slot or return the faulty card rather than damaging both the motherboard and the card.

It is good practice to spread out cards as far apart from each other as possible if you can. This
gives more breathing room and sensitive electronics will cool better and perform more reliably.

NOTE

Before Continuing onto section 2.11 – Connecting External Devices, make sure everything is
properly connected. Things like jumpers and case wiring are the most common causes of
troubleshooting frustrations, both for the end-user and for any company doing technical support.

YOU MUST unplug the power connector to the motherboard before performing
system hardware changes, to avoid having your motherboard boot-up
automatically, due to the PCI v2.2 spec.

22

http://www.TYAN.com

2.11 – Connecting External Devices

Connecting external devices to the motherboard is an easy task. The standard devices you should
expect to plug into the motherboard are keyboards, mice, and printer cables. The following
diagram will detail the ATX port stack for the following board:

S2720 Thunder i7500

At times, the PS/2 ports for keyboard and mice may be mixed up. Simply remember that the port
that is closest to the motherboard belongs to the keyboard and the one on top belongs to the
mouse.

Besides being used primarily to connect printers, the Printer Port is also used for devices such as
Zip drive, some external CD-RW drives and or other external devices. More on the uncommon
side these days are the Serial Ports. They were primarily used to connect external modems, but
most modems today are using USB or are installed internally.

TIP: While the ports have been created to accept connectors in only one direction, make sure to
be careful when inserting connectors. At times, attaching connectors in the incorrect orientation
can damage, bend and or break the pins.

2.12 – Installing the Power Supply

There are two power connectors on your Thunder i7500. By default, the Thunder i7500 requires
that you have an EPS12V power supply that has a 24-pin and an 8-pin power connector. Please
be aware that ATX 2.x, ATX12V and dual AMD (24+8-pin) power supplies are not compatible
with the board nor would they supply enough power.

1. Disconnect power supply from electrical outlet

2. Connect EPS 12V 8-pin power connector

3. Connect EPS 12V 24-pin power connector

4. Connect power cable to power supply to power outlet

Make sure you have connected BOTH the 24-pin and 8-pin connectors before attempting to
apply power to the board.

2.13 – Finishing Up

Congratulations on making it this far! You’re finished setting up the hardware aspect of your
computer. Before closing up your chassis, make sure that all cables and wires are connected
properly, especially IDE cables and most importantly, jumper cables. You may have difficulty
powering on your system if you properly connect motherboard jumpers.

Setting up your computer on a hardware level will probably be one of the easiest things to do if
you carefully followed these instructions. Hopefully, by the time you’re reading this, you should
already have enough experience to set up another computer without much aid of a manual.

In the rare circumstance that you experienced difficulty even though the instructions herein were
followed, you can find help by asking your vendor for assistance. If they are not available for
assistance, please find setup information and documentation online at our website or by calling

your vendor’s support line.

Chapter 3: BIOS Setup

Installation

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 the BIOS that can be
used to configure your system.

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.

This manual describes the BIOS setup program. The setup program lets you modify basic
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 BIOS in your motherboard is customized version of industry-standard BIOS for IBM PC AT­compatible personal computers. It supports the Intel Xeon family of processors, and other
compatible processors. The BIOS provides critical low-level support for the system central
processing component, memory, and I/O subsystems.

The 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 this BIOS setup program.

Starting Setup

The BIOS is immediately activated when you turn on the computer. The BIOS reads system
configuration in CMOS RAM and begins the process of checking out the system and configuring it
through the Power-On Self Tests (POST).

When these preliminary tests are complete, the BIOS seeks an operating system on one of the
data storage devices (hard drive, CD-ROM, etc) which you can define. If one is found, the BIOS
will launch that operating system and hand control ov er to it. You can enter the BIOS setup by
pressing the [DEL] key when the machine first starts and shows the memory count.

25

http://www.TYAN.com

Setup Basics

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

Left/Right Arrow Keys Change from one menu to the

Up/Down Arrow Keys More between selections

Getting Help
Pressing [F1] will 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 the changes
with the BIOS setup program, you can restart the computer by holding the power button down until
the computer shuts off (usually within 4 seconds).

The best advice is to alter only settings that you thoroughly understand. In particular do not
change settings in the Chipset section unless you are absolutely sure you need to. The Chipset
defaults were carefully chosen by TYAN or your system manufacturer for the best performance
and reliability. Even a seemingly small change to the Chipset setup options may cause the system
to become unstable or unusable.

Setup Variations
Not all systems have the same BIOS setup layout or options. While the basic look and function of

the BIOS setup remains more or less the same for most systems, the appearance of your Setup
screen may differ from the screen shown here. Each system design and chipset combination
requires custom configurations. In addition, the final appearance of the Setup program depends
on your system designer. Your system designer can decide that certain items should not be
available for user configuration, and remove them from the BIOS setup program.

NOTE: If you experience problems with setting up your system, always check the following things
in the following order:

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 .

4.2 Beep Codes

Fatal errors, which halt the boot process are communicated through a series of audible beeps. For
example, if the BIOS POST can initialize the video but an error occurs, an error message will be
displayed. If it cannot display the message, it will report the error as a series of beeps.

The most common type of error is memory error:

Memory not installed or memory not seated or using unbuffered DIMM in the socket
properly. If this occurs, the board will beep continuously and will not stop until power off.
Please ensure that the correct type of memory is installed in the correct location.

Only x4 -OR- x8 modules can be installed and NOT both. Ensure that the first two modules
are installed in sockets A1 and B1.

If you get this error, please check your memory configuration, order, type, and check for faulty
modules. Please check our website for memory compatibility.

Before calling your vendor or calling TYAN Tech Support, be sure that you know how many beeps
your board made, and how long the beeps were. Also have other information such as your
attached add-in cards, drives and OS to help speed up the support process and come to a
possible solution faster.

4.3 Flash Utility

Every BIOS file is unique for the motherboard it was designed for. For Flash Utilities, BIOS
downloads, and information on how to properly use the Flash Utility with your motherboard, you
must check the TYAN website: http://www.TYAN.com/

NOTE

Please be aware that by flashing your BIOS, you agree that in the even of a BIOS
flash failure, you must contact 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.

Appendix II: 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 memory. 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.

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 (BIOS Boot Specification): is a feature within the BIOS that creates, prioritizes, and
maintains a list of all Initial Program Load (IPL) devices, and then stores that list in NVRAM. IPL
devices have the ability to load and execute an OS, as well as provide the ability to return to the
BIOS if the OS load process fails for some reason. At that point, the next IPL device is called upon
to attempt loading of the OS.

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 permanently saved.

Bus: a data pathway. The term is used especially to refer to the connection between the
processor and system m emory, 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 lowers 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 4GB of regular memory.

37

http://www.TYAN.com

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 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 inactive 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): is a technology designed to double the clock speed of the memory. 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.

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
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.

ECC (Error Correction Code or Error Checking and Correcting): allows data to be checked for
errors during run-time. Errors can subsequently be corrected at the same time that they’re found.

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

EMRL: Embedded RAID Logic. An Adaptec specific RAID technology.
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 causing a loss of service, such as in a RAID system.

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

38

http://www.TYAN.com

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.
I/O (Input/Output): the connection between your computer and another piece of hardware

(mouse, keyboard, etc.)
Initial Program Load (IPL): a feature built into BBS-compliant devices, describing those devices

as capable of loading and executing an OS, as well as being able to provide control back to the
BIOS if the loading attempt fails.

IPL: see Initial Program Load.
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 or 64-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 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): software timers that count down the number of
seconds or minutes 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-P lay
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 systems that are not Plug-n-Play require you to reconfigure your system each time
you add or change any part of your hardware.

PXE (Preboot Execution Environment): one of four components that together make up the
Wired for Management 2.0 baseline specification. PXE was designed to define a standard set of
preboot protocol services within a client, towards the goal of allowing networked-based booting to
boot using industry standard protocols.

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 will appear as a single drive to the operating system. RAID level 0 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.

RAIDIOS: RAID I/O Steering (Intel)
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).

SCSI Interrupt Steering Logic (SISL): Architecture that allows a RAID controller, such as
AcceleRAID 150, 200 or 250, to implement RAID on a system board-embedded SCSI bus or a set
of SCSI busses. SISL: SCSI Interrupt Steering Logic ( LSI ) (only on LSI SCSI boards)

SIMM (Single In -line Memory Module): formally the most common form of RAM for
motherboards. They must be installed in pairs, and do not have the carryi ng capacity or the speed
of DIMM modules.

Sleep/Suspend mode: in this mode, all devices except the CPU shut down.
SDRAM (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 hard drives shut down; all other devices continue to

operate normally.

Striping: see RAID
UltraDMA-33/66/100: a fast version of the old DMA channel. UltraDMA is also called UltraATA.

Without proper UltraDMA controller, your system cannot take advantage of higher data transfer
rates of the new UltraDMA/UltraATA hard drives.

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 scanning properties of the monitor.
ZCR: Zero Channel RAID. PCI card that allows a RAID card to use the onboard SCSI chip, thus

lowering cost of RAID solution
ZIF Socket (Zero Insertion Force socket): these sockets make it possible to insert CPUs without

damaging the sensitive CPU pins. The CPU is lightly placed in an open ZIF socket, and a lever is
pulled down. This shift the processor over and down, guiding into the board and locking it into
place.

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 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).
