Viglen, EMC and the ‘CE’ mark

CE Marking

European standards are being harmonised across borders. If products comply with the same standards in all
European countries, product exporting and importing is made simple - paving our way to a common market. If
you buy a product with a 'CE' mark on it (shown below), on the box, in the manual, or on the guarantee - it
complies with the currently enforced directive(s).

Introduction to EMC

EMC (Electromagnetic Compatibility) is the term used to describe certain issues with RF (Radio Frequency)
energy. Electrical items should be designed so they do not interfere with each other through RF emissions. E.g.
If you turn on your microwave, your television shouldn't display interference if both items are CE marked to the
EMC directive.

If emitted RF energy is not kept low, it can interfere with other electrical circuitry - E.g. Cars Automatic Braking
Systems have been known to activate by themselves while in a strong RF field. As this has obvious
repercussions ALL electrical products likely to cause RF related problems have to be 'CE' marked from 1st
January 1996 onwards.

If a product conforms to the EMC directive, not only should its RF emissions be very low, but its immunity to RF
energy (and other types) should be high. The apparatus has to resist many 'real world' phenomena such as
static shocks and mains voltage transients.

Viglen’s Environment laboratory

To gain a 'CE' mark, the Viglen computer range has had to undergo many difficult tests to ensure it is
Electromagnetically Compatible. These are carried out in the in-house 'Environment lab' at Viglen Headquarters.
We have made every effort to guarantee that each computer leaving our factory complies fully with the correct
standards. To ensure the computer system maintains compliance throughout its functional life, it is essential you
follow these guidelines.

¾ Install the system according to Viglen’s instructions
¾ If you open up your Viglen:

¾ Keep internal cabling in place as supplied.
¾ Ensure the lid is tightly secured afterwards
¾ Do not remove drive bay shields unless installing a 'CE' marked peripheral in its place
¾ The clips or ‘bumps' around the lips of the case increase conductivity - do not remove or damage.
¾ Do not remove the ferrite ring from the L.E.D cables.
¾ Only use your Viglen computer with 'CE' marked peripherals

This system has been tested in accordance with European standards for use in residential and light industrial
areas-this specifies a 10 meter testing radius for emissions and immunity. If you do experience any adverse
affects which you think might be related to your computer, try moving it at least 10 meters away from the affected
item. If you still experience problems, contact Viglen’s Technical Support department who will put you straight
through to an EMC engineer - s/he will do everything possible to help. If modifications are made to your Viglen
computer system, it might breach EMC regulations. Viglen take no responsibility (with regards to EMC
characteristics) of equipment which has been tampered with or modified.

The Accelerated Graphics Port (AGP) is a high-performance interconnect for
graphic-intensive applications, such as 3D applications. AGP is independent of the
PCI bus and is intended for exclusive use with graphical-display devices. AGP
overcomes certain limitations of the PCI bus related to handling a large amount of
graphics data with the following performance features:

• Pipelined-memory read and write operations that hide memory access
latency.

• Demultiplexing of address and data on the bus for near 100 percent bus
efficiency.

• AC timing for 133 MHz data transfer rates, allowing data throughput of 500
MB/sec.

Realtek 8100C Platform LAN Connect Device

The Realtek 8100C component provides an interface to the back panel RJ-45
connector with integrated LEDs. This physical interface may alternately be provided
via the CNR connector.
The Realtek 8100C provides the following functions:

• Basic 10/100 Ethernet LAN Connectivity

• Supports RJ-45 connector with status indicator LEDs

• Full driver compatibility

• Advanced Power Management support

• Programmable transit threshold

• Configuration EEPROM that contains the MAC address

RJ-45 LAN Connector LEDs

selected.

Yellow Off LAN link is not

established.
Yellow On (steady state) LAN link is established.
Yellow On (brighter and pulsing) The computer is

communicating with

another computer on

the LAN.

Universal Serial Bus (USB)

The motherboard has four USB ports and a further four can be added via internal
headers; one USB peripheral can be connected to each port. For more than eight
USB devices, an external hub can be connected to either port. The motherboard
fully supports the universal host controller interface (UHCI) and uses UHCI­compatible software drivers.

V1.0 VIG555M Motherboard Manual

USB features include:

• Self-identifying peripherals that can be plugged in while the computer is
running.

• Automatic mapping of function to driver and configuration.

• Supports isochronous and asynchronous transfer types over the same set of

wires.

• Supports up to 127 physical devices.

• Guaranteed bandwidth and low latencies appropriate for telephony, audio,

and other applications.

• Error-handling and fault-recovery mechanisms built into the protocol.

NOTE: Computer systems that have an unshielded cable attached to a USB port

may not meet FCC Class B requirements, even if no device or a low-speed (sub­channel) USB device is attached to the cable. Use shielded cable that meets the
requirements for high-speed (fully rated) devices.

IDE Support

The motherboard has two independent bus-mastering PCI IDE interfaces. These
interfaces support PIO Mode 3, PIO Mode 4, ATAPI devices (e.g., CD-ROM), Ultra
DMA/33, Ultra DMA/66, Ultra DMA/100 & Ultra DMA/133 synchronous-DMA mode
transfers. The BIOS supports logical block addressing (LBA) and extended cylinder
head sector (ECHS) translation modes. The BIOS automatically detects the IDE
device transfer rate and translation mode.

Programmed I/O operations usually require a substantial amount of processor
bandwidth. However, in multitasking operating systems, the bandwidth freed by bus
mastering IDE can be devoted to other tasks while disk transfers are occurring.

LS-120 Support

LS-120 MB Diskette technology enables you to store 120MB of data on a single, 3.5”
removable diskette. LS-120 technology is backward (both read and write)
compatible with 1.44MB and 720KB DOS-formatted diskette and is supported by
Windows 95 and Windows NT operating system.

The Vig555M board allows connection of an LS-120 compatible drive and a standard
3½” floppy drive. The LS-120 drive can be configured as a boot device before a
floppy drive, if selected in the BIOS setup utility.

Note:

If you connect an LS-120 drive to an IDE connector and configure it as the “A” drive
and configure a standard 3.5” floppy as “B” drive, the standard floppy must be
connected to the floppy drive cable’s “A” connector (the connector at the end of the
cable).

The BIOS setup utility can be configured to boot firstly from either the LS120 or
standard 3½” floppy drive.

V1.0 VIG555M Motherboard Manual

Real-Time Clock, CMOS SRAM, and Battery

The real-time clock is compatible with DS1287 and MC146818 components. The
clock provides a time-of-day clock and a multi-century calendar with alarm features
and century rollover. The real-time clock supports 256 bytes of battery-backed
CMOS SRAM in two banks that are reserved for BIOS use.

The time, date, and CMOS values can be specified in the Setup program. The
CMOS values can be returned to their defaults by using the Setup program.
An external coin-cell (CR 2032) battery powers the real-time clock and CMOS
memory. When the computer is not plugged into a wall socket, the battery has an
estimated life of three years. When the computer is plugged in, the 3.3-V standby
current from the power supply extends the life of the battery. The clock is accurate
to ± 13 minutes/year at 25 ºC with 3.3 V applied.

I/O Interface Controller

The motherboard uses the SMC FDC37C777 I/O controller which features:

• Serial ports:

• ISA Plug-and-Play compatible register set.

• PCI PME interface.

• Intelligent auto power management:
⎯ Shadowed write-only registers for ACPI compliance.
⎯ Programmable wake up event interface.

By default, the I/O controller interfaces are automatically configured during boot up.
The I/O controller can also be manually configured in the Setup program

.

Serial Ports

One 9-pin D-Sub serial port connector is located on the back panel and is compatible
with NS16C550 UARTs.

V1.0 VIG555M Motherboard Manual

11

Parallel Port

The connector for the multimode bidirectional parallel port is a 25-pin D-Sub

configured for the following:

• Compatible (standard mode).

• Bidirectional (PS/2 compatible).

• Extended Parallel Port (EPP).

• Enhanced Capabilities Port (ECP).

Floppy Controller

The I/O controller is software compatible with the N82077 floppy drive controllers
and supports both PC-AT and PS/2 modes. In the Setup program, the floppy
interface can be configured for the following floppy drive capacities and sizes:

• 360 KB, 5.25-inch

• 1.2 MB, 5.25-inch

• 720 KB, 3.5-inch

• 1.2 MB, 3.5-inch (driver required)

• 1.25/1.44 MB, 3.5-inch

• 2.88 MB, 3.5-inch

PS/2 Keyboard and Mouse Interface

PS/2 keyboard and mouse connectors are located on the back panel. The +5 V lines
to these connectors are protected with a PolySwitch circuit that, like a self-healing
fuse, re-establishes the connection after an over-current condition is removed.

The keyboard controller supports the hot-key sequence <Ctrl><Alt><Del> for a
software reset. This key sequence resets the computer’s software by jumping to the
beginning of the BIOS code and running the Power-On Self Test (POST).

Audio Subsystem

The Vig555M board has multiple AC ’97 V 1.03 compliant audio features including
an Analog Devices ALC 655 codec.

The audio subsystem includes these features:

• Split digital/analog architecture for improved S/N (signal-to-noise) ratio: ≥ 85dB –
measured at line out, from any analog input, including line in, CD-ROM, and
auxiliary line in.

• 3-D stereo enhancement

• Power management support for APM 1.2 and ACPI 1.0 (driver dependant)

• Audio inputs:

o Four analog line-level stereo inputs for connection from line in, CD, video

source line in and aux

o Two analog line-level inputs for speakerphone input and PC beep

o One mono microphone input

• Audio outputs:

o Stereo line-level output
o Mono output for speakerphone

Management Extension Component

System BIOS

The system BIOS, from Phoenix Technology, provides ISA and PCI compatibility.
The BIOS is contained in a flash memory device on the system board. The BIOS
provides the power-on self test (POST), the system Set-up program, a PCI and IDE
auto-configuration utility, and BIOS recovery code.

PCI Auto Configuration

The PCI auto-configuration utility works in conjunction with the Set-up program to
support using PCI add-in boards in the system. When you turn on the system power
after installing a PCI board, the BIOS automatically configures interrupts, DMA
channels, I/O space, and so on. Since PCI add-in boards use the same interrupt
resources as ISA add-in boards, you must specify the interrupts used by ISA boards
in the set-up program. The PCI auto-configuration program complies with version 2.1
of the PCI BIOS specification.

IDE Auto Configuration

If you install an IDE drive in the system, the IDE auto-configuration utility
automatically detects and configures the drive for operation in the system. This
utility eliminates the need to enter the Set-up program after you install an IDE drive.

Expansion Slots

The system has two PCI bus add-in card connectors and One AGP universal
connector.

Make sure you are earthed and free of static charge before you open the computer
case. If you are unsure about upgrading your computer, return it to Viglen so a
qualified engineer can perform the upgrade.

STEPS TO TAKE TO PREVENT STATIC DISCHARGE:

1. The best way to prevent static discharge is to buy an anti-static strap from your
local electrical shop. While you are wearing the strap and it is earthed, static
charge will be harmlessly bled to ground.

2. Do not remove the component from its anti-static protective packaging until you
are about to install it.

3. Hold boards by the edges - try not to touch components / interface strips etc.

NOTE: We recommend that you return your computer to the service department for

upgrading. Any work carried out is fully guaranteed. Upgrades should only be carried
out by persons who are familiar with handling IC's, as incorrect installation will
invalidate the guarantee.

Overview of Jumper Settings

The VIG555M motherboard contains the latest technology to offer an almost
jumperless configuration. All Pentium® 4 CPUs are automatically detected and the
Speed is automatically set from the information provided by the CPU.

The only jumpers present on the motherboard are for clearing all the CMOS settings.
In the unlikely event of the CMOS becoming corrupted then jumper JP1 can be set to
clear the contents of the CMOS, and for write protecting the BIOS.

CAUTION!

Never remove jumpers using large pliers as this can damage the pins. The best way
to remove a jumper is to use a small pair of tweezers or fine needle-nosed pliers.

Never remove a jumper when the computer is switch on. Always switch the
computer off first.

Troubleshooting Procedures

This section provides a step-by-step troubleshooting procedure to identify a problem
and locate its source.

CAUTION!

1. Turn off the system and any peripheral devices before you disconnect any
peripheral cables from the system. Otherwise, you can permanently damage the
system or the peripheral devices.

2. Make sure the system is plugged into a properly grounded power outlet.

3. Make sure your keyboard and video display are correctly connected to the
system. Turn on the video display, and turn up its brightness and contrast
controls to at least two-thirds of the maximum (refer to the documentation supplied
with the video display).

4. If the operating system normally loads from the hard dis k dr ive, make sure there is
no diskette in the diskette drive. If the operating system normally loads from a
diskette, insert the operating system diskette into the drive.

5. Turn on the system. If the power indicator does not light, but the system seems
to be operating normally, the indicator is probably defective. Monitor the power-on
self test (POST) execution. Each time you turn on the system, the POST checks
the system board, memory, keyboard, and certain peripheral devices.

NOTE: If the POST does not detect any errors, the system beeps once and boots

up.
Errors that do not prevent the boot process (non-fatal errors) display a message that

looks similar to the following:
Error Message Line 1

Error Message Line 2
Press <F2> for Set-up, <F1> to Boot

You can note the error and press <F1> to resume the boot- up process, or
<F2> to enter Set-up.

Errors that prevent the boot process from continuing (fatal errors), are communicated
by a series of audible beeps. If this type of error occurs, refer to the error codes and
messages listed at the end of this chapter.

6. Confirm that the operating system has loaded.

Problems Operating Add-in Boards

Problems related to add-in boards are usually related to improper board installation
or interrupt and address conflicts. Go through the checklist below to see if you can
correct the problem. If the problem persists after you have checked and corrected all
of these items, contact the board vendor's customer service representative.

Did you install the add-in board according to the manufacturer’s instructions?
Check the documentation that came with the board. Are all cables installed properly?

The following items are suggestions for troubleshooting problems related to PCI/ISA
legacy (non-Plug and Play) add-in boards.

• If the PCI/ISA board uses an interrupt, run Set-up and set the interrupt that is

being used by the PCI/ISA board to Used by PCI/ISA Card. Please refer to the
BIOS manual for details of how to do this.

• If the PCI/ISA legacy board uses memory space between 80000H - 9FFFFH, run

Set-up and set conventional memory to 256 K.

• If the PCI/ISA legacy board uses shared memory between C8000H - DFFFH, run

Set-up and enable shared memory for the appropriate memory space.

Chapter 4: System BIOS

What is the BIOS?

The BIOS (Basic Input Output System) is an important piece of software which is
stored in a ROM (Read Only Memory) chip inside the computer. It consists of the
basic instructions for controlling the disk drives, hard disk, keyboard and
serial/parallel ports. The BIOS also keeps a list of the specifications of the computer
in battery-backed RAM (also known as the CMOS RAM) and provides a special
Setup program to change this information.

The BIOS in your Viglen computer is guaranteed to be fully compatible with the IBM
BIOS. It has been written by Phoenix Award BIOS, an industrial leader in the field of
BIOS software.

The Power-On sequence

When the computer is first switched on, certain instructions in the BIOS are executed
to test various parts of the machine. This is known as the POST (Power-On Self
Test) routine. When you switch the computer on (or when you press the Reset
button or press <Ctrl> + <Alt>+ <Delete> keys, which has the same effect), you can
see on the monitor that it counts through the memory, testing it. The floppy disk
drives are then accessed and tested, and the various interfaces are checked. If there
are any errors, a message is displayed on the screen.

Having passed all the tests, and if you have activated the password facility, the BIOS
then asks you to enter the boot password to continue. The following section
describes how to do this. The BIOS then loads the operating system, either - MS
DOS, Windows 98SE, OS/2 or NetWare, etc. - from the hard disk (or floppy disk if
one is inserted in Drive A: The computer is then ready for use.

V1.0 VIG555M Motherboard Manual

Phoenix Award BIOS

Introduction

The motherboard uses a Phoenix BIOS, which is stored in flash memory and can be
upgraded using a disk-based program. In addition to the BIOS, the flash memory
contains the Setup program, Power-On Self Test (POST), Advanced Power
Management (APM), the PCI auto-configuration utility, and is Windows 95-ready
Plug and Play. This motherboard supports system BIOS shadowing, allowing the
BIOS to execute from 64-bit onboard write-protected DRAM.

The BIOS displays a message during POST identifying the type of BIOS and the
revision code.

BIOS Upgrades

A new version of the BIOS can be upgraded from a diskette using the AFUDOS.EXE
utility that is available from the Viglen FTP site. This utility does BIOS upgrades as
follows:

• Updates the flash BIOS from a file on a disk.

• Updates the language section of the BIOS.

• Makes sure that the upgrade BIOS matches the target system to prevent

accidentally installing a BIOS for a different type of system.

BIOS upgrades and the AWFL855A.EXE utility may be available online at
www.viglen.co.uk or by request.

NOTE: Please review the instructions distributed with the upgrade utility before

attempting a BIOS upgrade.

Using AWDFLASH to update the BIOS

The BIOS can be updated using the AWFL855A.EXE utility in DOS environment.

• Copy the AWFL855A.EXE utility to the bootable floppy disk that contains the

BIOS file.

• Boot the system from the floppy disk.

• At the DOS prompt, type the command line:

Awfl855a filename.bin

Where “filename.bin” means the latest (or original) BIOS file that you copied to the
bootable floppy disk.
The whole process is automated and needs no input from the user.

DO NOT shutdown or reset the system while updating the BIOS! Doing so may

cause system boot failure!

V1.0 VIG555M Motherboard Manual

38

When the BIOS update process is complete, the utility reboots the system.
Once the system has been restarted it will hold on the Pre-BIOS screen. At this
stage the following need to be completed before starting windows.

1. The system will halt on pre-BIOS, at this point you need to shut the machine
down.

2. Reboot the computer.

3. System will holt on the pre-BIOS screen and display an error message
(CMOS checksum error – Defaults loaded)

4. Enter the BIOS setup by pressing DEL

5. Once in the setup load the optimized settings by selecting ‘Load Optimized
Defaults’

6. Exit the setup by selecting ‘Save & Exit setup’.

7. Now boot in to windows.

When you reboot the system it will hold on the Pre-BIOS screen. At this stage there
will be an error message shown and details of the current BIOS. Check the BIOS
version. The BIOS version is made up of the BIOS file name, version, build and time
of flash. E.g.

W7103SMS V1.0 121404 14:27:50

The V number is the version, in this case Version 1.0.

This requires the user to choose one of two options. Either F1 to continue with the
default BIOS settings loaded or DEL to enter the BIOS setup.
Enter the BIOS setup and select ‘load optimized default’. Then select ‘Save & Exit
setup’.

Configuring the Motherboard using BIOS Setup

Before You Begin

CAUTION!

• Always follow the steps in each procedure in the correct order.

• Set up a log to record information about your computer, such as model, serial

numbers, installed options, and configuration information.

• Use an anti-static wrist strap and a conductive foam pad when working on the
motherboard.

WARNINGS

The procedures in this chapter assume familiarity with the general terminology
associated with personal computers and with the safety practices and regulatory
compliance required for using and modifying electronic equipment.

Disconnect the computer from its power source and from any telecommunications
links, networks, or modems before performing any of the procedures described in
this chapter. Failure to disconnect power, telecommunications links, networks, or
modems before you open the computer or perform any procedures can result in
personal injury or equipment damage. Some circuitry on the motherboard may
continue to operate even though the front panel power button is off.

CAUTION!

Electrostatic discharge (ESD) can damage components. Perform the procedures
described in this chapter only at an ESD workstation. If such a station is not
available, you can provide some ESD protection by wearing an anti-static wrist strap
and attaching it to a metal part of the computer chassis.

BIOS Setup Program

This motherboard supports a programmable firmware hub (FWH) that you can

update using the provided utility described in section “2.1 Managing and updating

your BIOS.”

Use the BIOS Setup program when you are installing a motherboard, reconfiguring
your system, or prompted to “Run Setup”. This section explains how to configure
your system using this utility.

Even if you are not prompted to use the Setup program, you may want to change the
configuration of your computer in the future. For example, you may want to enable
the security password feature or change the power management settings. This
requires you to reconfigure your system using the BIOS Setup program so that the
computer can recognise these changes and record them in the CMOS RAM of the
firmware hub.

The firmware hub on the motherboard stores the Setup utility. When you start up the
computer, the system provides you with the opportunity to run this program. Press
<Delete> during the Power-On Self Test (POST) to enter the Setup utility. Otherwise,
POST continues with its test routines.

If you wish to enter Setup after POST, restart the system by pressing <Ctrl> + <Alt>
+ <Delete>, or by pressing the reset button on the system chassis. You can also
restart by turning the system off and then back on. Do this last option only if the first
two failed.

The Setup program is designed to make it as easy to use as possible. It is a menu
driven program, which means you can scroll through the various sub-menus and
make your selections from the available options using the navigation keys.

NOTE: If the system becomes unstable after changing any BIOS settings, load the

default settings to ensure system stability. Select the Load Default Settings item
under the Exit Menu.

Chapter 5: Technical Information

NOTE: This chapter is indented for experienced users only, and only to be used as a

reference. Changes to or modify any of the components/ connectors listed herein
can and will seriously damage your system, including the motherboard, CPU and/or
any other hardware.

You do not need to read this chapter to configure your motherboard. If you are not
sure about the details listed herein, please skip and disregard them.

Enhanced IDE

IDE has been used in computer systems for some time, and has been a cheap
solution to data storage. It has now been realised that traditional IDE has its
limitations and thus needed to be improved. This was where Enhanced IDE came

from. The main developments to the IDE interface are:

• Support hard drives of capacity greater than 528MB. This is achieved through
BIOS changes.

• Improved data transfer rates. Transfer rates of 1-3MB/sec were the best to be
expected from older IDE drives. With local bus technology this increased to about
6MB/sec. Now with multimedia applications, requiring vast amounts of
information, even faster transfers rates were needed. Now drives with Enhanced
IDE controllers can deliver up to 13MB/sec which is in the region of SCSI-2
performance.

• Dual-IDE channels have now been added which allows up to four IDE drives to be
supported by the system. Each channel supporting two IDE devices.

• Non disk IDE peripherals have been developed (IDE CD-ROMs, IDE tape
streamers) which can be simply attached to the one channel requiring no special
hardware (requiring the use of an ISA slot) or complicated drivers. This is a
standard interface meaning that any IDE CD-ROM or tape streamer can be
attached.

Operating Systems and Hard Drives

Standard CHS is the translation that has been used for years. Its use limits IDE
capacity to maximum of 528MB regardless of the size of the drive used.

Logical Block mode overcomes the 528MB maximum size limitation imposed by the
Standard CHS mode. It should be used only when the drive supports LBA (Logical
Block Addressing), and the OS supports LBA, or uses the BIOS to access the disk.

Extended CHS mode also overcomes the 528MB maximum size limitation imposed
by Standard CHS mode. It can be used with drives which are larger than 528MB that
do not support LBA.

V1.0 VIG555M Motherboard Manual

65

Auto Detected allows the BIOS to examine the drive and determine the optimal
mode. The first choice is to utilise Logical Block mode if it is supported by the drive.
The second choice is to utilise Extended CHS mode if the drive topology allows. If
neither of the above methods is possible, the Standard CHS mode is used.

Different operating systems have different abilities regarding IDE translation mode.

UNIX operating systems (as currently implemented) do not support either LBA or
ECHS and must utilise the standard CHS method. UNIX can support drives larger
than 528MB, but does so in its own way.

OS/2 2.1 and OS/2 Warp can support LBA, ECHS or standard CHS methods. Note
that LBA support may require a switch setting on an OS/2 driver in order to operate
in that mode.

OS/2 2.0 & Novel NetWare can support either ECHS or standard CHS methods. In
order to use LBA with NetWare a driver that supports current parameters must be
used.OS/2 2.0 does not support LBA.

DOS & Windows can use LBA, ECHS or standard CHS methods. The '32-bit Disk
Access' driver built into Windows WDCTRL.386 can only be used with the standard
CHS method, To use either LBA or ECHS method and '32-bit Disk Access' an
alternative .386 driver must be installed, this combination will also provide the best
performance. If this driver is not installed and the drive fitted to the system supports
Type F DMA on the ISA interface or Mode 3 on the PCI interface then higher
performance will be achieved by NOT using '32-bit Disk Access'.

V1.0 VIG555M Motherboard Manual

Power Supply Connector

When used with an ATX-compliant power supply that supports remote power on/off,
the motherboard can turn off the system power through software control.

To enable soft-off control in software, advanced power management must be
enabled in the Setup program and in the operating system. When the system BIOS
receives the correct APM command from the operating system, the BIOS turns off
power to the computer.

With soft-off enabled, if power to the computer is interrupted by a power outage or a
disconnected power cord, when power resumes, the computer returns to the power
state it was in before power was interrupted (on or off).

Other Information

Reliability

The mean time between failures (MTBF) prediction is calculated using component
and subassembly random failure rates. The calculation is based on the Bellcore
Reliability Prediction Procedure, TR-NWT-000332, Issue 4, September 1991.

The MTBF prediction is for:

• Redesigning the motherboard for alternate components if failure rates
exceed reliability expectations.

• Estimating repair rates and spare parts requirements.

MTBF data is calculated from predicted data @ 55 °C.

The MTBF prediction for the motherboard is 286,877 hours.

Chapter 6: Glossary

BIOS

(Basic Input Output System) This is software stored on a chip and consists of the
instructions necessary for the computer to function. The System BIOS contains the
instructions for the keyboard, disk drives etc., and the VGA BIOS controls the VGA
graphics card.

CPU

Central Processing Unit. This is the main piece of equipment on the motherboard.
The CPU processes data, tells memory what to store and the video card what to
display.

Default

The configuration of the system when it is switched on or the standard settings
before any changes are made.

DIMM

Dual In-Line Memory Module, a type of memory module used for the systems main
memory.

Driver

A piece of software which is used by application software to control some special
features. Each graphics board and printer requires its own driver.

D-Type

A common type of connector used for connecting printers, serial ports, game port,
and many other types of interface.

DRAM

Dynamic Ram used for main system memory, providing a moderately fast but cheap
storage solution.

FDC

Floppy Disk Controller - the interface for connecting floppy disk drives to the
computer.

Hercules

A monochrome graphics video mode which first appeared in the Hercules graphics
card. Provides a resolution of 720 by 348 pixels.

IDE

Integrated Drive Electronics - currently the most popular type of interface for hard
disk drives. Much of the circuitry previously required on hard disk controller cards is
now integrated on the hard disk itself.

Interface

The electronics providing a connection between two pieces of equipment. For
example, a printer interface connects a computer to a printer.

V1.0 VIG555M Motherboard Manual

73

Interlace

The mode the graphics card uses to refresh a monitor screen. When the graphics is
in interlace mode, the frequency of the display update is lower than in non-interlace
mode. This causes a slight flicker, so generally non-interlaced mode is better if the
monitor supports it.

L.E.D.

Light Emitting Diode - a light which indicates activity - for example hard disk access.

PCI

Peripheral Component Interface. It became apparent to manufacturers that the
8MHz AT ISA BUS on the standard PC was just not fast enough for today's
applications, and so PCI was invented. It is a high speed data bus that carries
information to and from components - known as 'Local Bus'.

RAM

Random Access Memory - the memory used by the computer for running programs

and storing data.

ROM

Read Only Memory - a memory chip which doesn't lose its data when the system is
switched off. It is used to store the System BIOS and VGA BIOS instructions. It is
slower than RAM.

Shadow Memory

The BIOS is normally stored in ROM. On certain systems it can be copied to RAM on
power up to make it go faster. This RAM is known as shadow memory. The System
BIOS is responsible for this copying.

Super VGA

Additional screen modes and capabilities provided over and above the standard
VGA defined by IBM.

VGA

Video Graphics Array - the graphics standard defined by IBM and provided on IBM's
PS/2 machines.
