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.

9
Accelerated Graphics Port (AGP)
The Vig556M features both integrated graphics and an AGP port. When using the integrated graphics then a dynamic portion of the main system memory is used as video memory. You can also use any AGP video card, with 4x/8x AGP performance. 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
10
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. 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 Vig556M 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.
11
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: Internal send/receive 16-byte FIFO buffer. Four internal 8-bit DMA options for the UART with SIR support (USI).
• Multimode bidirectional parallel port: Standard mode, IBM and Centronics compatible. Enhanced parallel port (EPP) mode with BIOS and driver support. High-speed extended capabilities port (ECP) mode.
• Floppy disk controller: N82077 compatible. Single diskette drive interface. 16-byte FIFO. High-performance digital data separator (DDS). PC-AT and PS/2 drive-mode support.
• Keyboard and mouse controller: Industry standard 8042A compatible. General-purpose microcontroller. 8-bit internal data bus.
• 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.
12
Parallel Port
The connector for the multimode bidirectional parallel port is a 25-pin D-Sub connector located on the back panel. In the Setup program, the parallel port can be 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 Vig556M 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
13
• 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.

Chapter 2: System Board Options
The VIG556M motherboard is capable of accepting Celeron® D, Pentium® 4 or Pentium® D CPU’s. RAM can be upgraded to a maximum of 2GB using DDR266, DDR333 or DDR400 SDRAM DIMMs Non ECC Unbuffered memory.
WARNING!
Unplug the system before carrying out the procedures described in this chapter. Failure to disconnect power before you open the system can result in personal injury or equipment damage. Hazardous voltage, current, and energy levels are present in this product. Power switch terminals can have hazardous Voltages present even when the power switch is off.
The procedures 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. Do not operate the system with the cover removed. Always replace the cover before turning on the system.
As the colours of the wires in the mains lead of this computer may not correspond with the coloured markings identifying the terminals in your plug precede as follows:
The wire which is coloured green-and-yellow must be connected to the terminal in the plug which is marked by the letter E or by the safety Earth symbol Q or coloured green or green-and-yellow.
The wire which is coloured blue must be connected to the terminal which is marked with the letter N or coloured black.
The wire which is coloured brown must be connected to the terminal which is marked with the letter L or coloured red.
CAUTION!
The Viglen VIG556M motherboard and associated components are sensitive electronic devices. A small static shock from your body can cause expensive damage to your equipment.
21
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.
22
Overview of Jumper Settings
The VIG556M motherboard contains the latest technology to offer an almost jumperless configuration. All Celeron® D, Pentium® 4 and Pentium® D 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.

Replacing the Clock/CMOS RAM Battery
A lithium battery is installed in a socket on the system board.
The battery has an estimated life expectancy of seven years. When the battery starts to weaken, it loses voltage; when the voltage drops below a certain level, the system settings stored in CMOS RAM (for example, the date and time) may be wrong.
If the battery fails, you will need to replace it with a CR2032 battery or an equivalent. As long as local ordinance permits, you may dispose of individual batteries as normal rubbish. Do not expose batteries to excessive heat or any naked flame. Keep all batteries away from children.
CAUTION!
Danger of explosion if the battery is incorrectly replaced. Replace only with the same or equivalent type recommended by Viglen. Discard used batteries according to manufacturer’s instructions.
The battery is listed as board component ‘S’ on the diagram on Figure 1.
To replace the battery, carry out the following:
1. Observe the precautions in “Before You Begin.”
2. Turn off all peripheral devices connected to the system.
3. Turn off the system.
4. Remove any components that are blocking access to the battery.
5. Figure 1 shows the battery location. Gently pry the battery free from its socket, taking care to note the "+" and "-" orientation of the battery (Figure 10).
6. Install the new battery in the socket.

Resetting the System
Before checking your system for hardware problems, it is always a good idea to try resetting your computer and see if a re-boot can solve the problem. Most software related problems can be solved simply by re-booting your PC.
Table 7: Resetting the System
To do the following Press
Soft boot: Clear the system memory and reload the operating system (also called warm reset).
<Ctrl + Alt + Del>
Cold boot: Clear the system memory, halt power to all peripherals, restart POST, and reload the operating system.
Power off/on or reset button (at front of the system)
33
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 disk drive, 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.
34
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.
38
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!
39
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’.
40
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.
41
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.
66
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'.

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.
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.
