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.
Install the system according to Viglen’s instructions If you open up your Viglen:
Keep internal cabling in place as supplied. Ensure the lid is tightly secured afterwards Do not remove drive bay shields unless installing a 'CE' marked peripheral in its place The clips or ‘bumps' around the lips of the case increase conductivity - do not remove or damage. Do not remove the ferrite ring from the L.E.D cables. 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.

Memory
Main Memory
The Vig550B Motherboard has T wo DDR DIMM sockets. Minimum memory size is 128MB; Maximum memory size is 2GB. The BIOS automatically detects memory type, size, and speed.
The motherboard supports the following memory features:
• 184-pin DIMMs.
• 400Mhz
• Un-Buffered Non-ECC DIMM.
RDRAM
Synchronous DRAM (SDRAM) improves memory performance through memory access that is synchronous with the memory clock. This simplifies the timing design and increases memory speed because all timing is dependent on the number of memory clock cycles.

The SiS 661FX chipset is the latest generation of desktop PCI set, it includes new features such as –
• 8x AGP Support
• ATA-133 IDE Hard drive support
• 800MHz Front Size Bus support
• ACPI & On-Now
9
Accelerated Graphics Port (AGP)
The Vig550B 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. There is an optional GPA (Graphics Performance Accelerator) modules which has a dedicated 4MB of video memory. You can also use any AGP video card, with 4x/8x AGP performance.
The Accelerated Graphics Port (AGP) is a high-performance interconnects 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.
RJ-45 LAN Connector LEDs
Two LEDs are built into the RJ-45 LAN connector. The following table describes the LED states when the board is powered up and the LAN subsystem is operating.
Table 1: LAN LED Status
LED Colour LED State Condition
Green Off 10 Mbit/sec data rate is selected.
Green On 100 Mbit/sec date rate is 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 Vig550B Motherboard has four USB ports; one USB peripheral can be connected to each port. For more than four USB devices, an external hub can be connected to either port. The motherboard fully supports the universal host controller interface (UHCI) and uses UHCI-compatible 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.
10
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 (sub-channel) USB device is attached to the cable. Use shielded cable that meets the requirements for high-speed (fully rated) devices.
IDE Support
The Vig550B 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 Vig550B 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 u tility.
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.
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 p lugged into a wall socket, the battery has an
11
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:
o Internal send/receive 16-byte FIFO buffer. o Four internal 8-bit DMA options for the UART with SIR support (USI).
• Multimode bidirectional parallel port:
o Standard mode, IBM and Centronics compatible. o Enhanced parallel port (EPP) mode with BIOS and driver support. o High-speed extended capabilities port (ECP) mode.
• Floppy disk controller:
o N82077 compatible. o Single diskette drive interface. o 16-byte FIFO. o High-performance digital data separator (DDS). o PC-AT and PS/2 drive-mode support.
• Keyboard and mouse controller:
o Industry standard 8042A compatible. o General-purpose microcontroller. o 8-bit internal data bus.
• ISA Plug-and-Play compatible register set.
• PCI PME interface.
• Intelligent auto power management:
o Shadowed write-only registers for ACPI compliance. o 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.
NOTE: If a dual serial port card is installed in a PCI slot, wake on LAN needs to be disabled, otherwise the system will not shutdown and stay off.
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:
• 1.25/1.44 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 Vig550B 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
13
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 ente r the Set-up program after you install an IDE drive.
Expansion Slots
The system has Three PCI bus add-in card connectors and One AGP universal connector.

Chapter 2: System Board Options
The VIG550B motherboard is capable of accepting Pentium® 4 CPU’s. RAM can be upgraded to a maximum of 2GB using 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 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 colo ured 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 Vig535b 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 component s / 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 Vig550B motherboard contains the latest technology to offer an almost jumper less configuration. All Pentium® 4 CPUs are automatically detected and the Speed is automatically set from the information provided by the CPU.
The only jumper present on the motherboard is 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.
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.
