Viglen, EMC and the ‘CE’ mark
CE Marking
European standards are being harmonised across borders. If products c omply 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 ite ms 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 Autom atic 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 th e in-house 'Environment lab' at Viglen Headquarters.
We have made every effort to guarantee that each computer leavi ng 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 dep artment who will put you straight
through to an EMC engineer - s/he will do everything possible to help. If modifications are made to your Vigle n
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.

IDE Support
The motherboard has one 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 Vig590M 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.
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.

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
These audio connectors are used for audio devices. You can differentiate the colour
of the audipo jacks for different audio sound effects.
• Line-In / RS-Out (Blue) - Line In is used for external CD player, tapeplayer or
other audio devices. Rear-Surround Out in 4/ 5.1 channel mode.

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 PCI Express X16
connector.

V1.0 VIG590M Motherboard Manual
20
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 VIG590MM motherboard contains the latest technology to offer an almost
jumperless configuration. All Intel® Core2 Duo 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.
