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 effects 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. XMA take no responsibility (with regards to EMC characteristics) of equipment which has
been tampered with or modified.

Figure 3: Memory configuration
NOTE: To be fully compliant with all applicable DDR SDRAM memory specifications, the board
should be populated with DIMMs that support the Serial Presence Detect (SPD) data structure.
This allows the BIOS to read the SPD data and program the chipset to accurately configure
memory settings for optimum performance. If non-SPD memory is installed, the BIOS will attempt
to correctly configure the memory settings, but performance and reliability may be impacted or
the DIMMs may not function under the determined frequency.
You may install varying memory sizes in DIMM1 and DIMM2. The system maps the total size of
the lower-sized channel for the dual-channel configuration. Any excess memory from the higher-
sized channel is then mapped for single-channel operation.
• According to Intel® CPU spec, DIMM voltage below 1.35V is recommended to protect the CPU.
• Due to the memory address limitation on 32-bit Windows® OS, when you install 4GB or more
memory on the motherboard, the actual usable memory for the OS can be about 3GB or less.
For effective use of memory, we recommend that you do any of the following:
- Use a maximum of 3 GB system memory if you are using a 32-bit Windows® OS.
- Install a 64-bit Windows® OS if you want to install 4GB or more on the motherboard.
For more details, refer to the Microsoft® support site at:
http://support.microsoft.com/kb/929605/en-us.
Memory Configurations
The Intel Core i7, Intel Core i5, Intel Core i3, and Intel Pentium processors support the
following types of memory organization:
Dual channel (Interleaved) mode. This mode offers the highest throughput for real world
applications. Dual channel mode is enabled when the installed memory capacities of both
DIMM channels are equal. Technology and device width can vary from one channel to the
other but the installed memory capacity for each channel must be equal. If different DIMM
speeds are used between channels, the slowest memory timing will be used.
Single channel (Asymmetric) mode. This mode is equivalent to single channel
bandwidth operation for real world applications. This mode is used when only a single DIMM
is installed or the memory capacities are unequal. Technology and device width can vary
from one channel to the other. If different DIMM speeds are used between channels, the
slowest memory timing will be used.

Real- Time Clock, CMOS RAM, and Battery
A coin-cell battery (CR2032) 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 standby current from the power supply
extends the life of the battery.
The clock is accurate to ± 13 minutes/year at 25 ºC with power applied through the
power supply 5V STBY rail.
NOTE: If the battery and AC power fail, date and time values will be reset and the user
will be notified during POST. When the voltage drops below a certain level, the BIOS
Setup program settings stored in CMOS RAM (for example, the date and time) might not
be accurate. Replace the battery with an equivalent one.
BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, and the
PCI/PCI Express and SATA auto-configuration utilities. The BIOS is stored in the Serial
Peripheral Interface (SPI) Flash memory device.
SATA Auto Configuration
If you install a SATA device (such as a hard disk drive) in your computer, the auto-
configuration utility in the BIOS automatically detects and configures the device for your
computer. You do not need to run the BIOS Setup program after installing a SATA
device. You can override the auto-configuration options by specifying manual
configuration in the BIOS Setup program.
PCI/PCI Express Auto Configuration
If you install a PCI Express add-in card in your computer, the PCI/PCI Express auto-
configuration utility in the BIOS automatically detects and configures the resources
(IRQs, DMA channels, and I/O space) for that add-in card. You do not need to run the
BIOS Setup program after you install a Conventional PCI or PCI Express add-in card.

BIOS Security Passwords
The BIOS includes security features that restrict whether the BIOS Setup program can
be accessed and who can boot the computer. An administrator password and a user
password can be set for the BIOS Setup and for booting the computer, with the following
restrictions:
The administrator password gives unrestricted access to view and change all Setup
options. If only the administrator password is set, pressing <Enter> at the password
prompt of Setup gives the user restricted access to Setup.
If both the administrator and user passwords are set, you must enter either the
administrator password or the user password to access Setup. Setup options are then
available for viewing and changing depending on whether the administrator or user
password was entered.
Setting a user password restricts who can boot the computer. The password prompt
is displayed before the computer is booted. If only the administrator password is set,
the computer boots without asking for a password. If both passwords are set, you can
enter either password to boot the computer.

BEFORE YOU BEGIN
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 Vig103M motherboard contains the latest technology to offer an almost jumperless
configuration. All Intel® Core 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 CLRTC 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.

System Board Jumper Settings
Do not move the jumper with the power on. Always turn off the power and unplug the power cord
from the computer before changing a jumper setting. Otherwise, the board could be damaged.
Clear CMOS Memory (2-pin JBAT1)
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the
CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM
data. The onboard button cell battery powers the RAM data in CMOS, which include system
setup information such as system passwords.
Figure 8: Clear CMOS jumper
To erase the RTC RAM:
1. Power off the computer and unplug the power cord
2. Use a jumper cap to short JBAT1 for about 5-10 seconds.
3. Remove the jumper cap from JBAT1.
4. Plug the power cord and power on the computer.
Except when clearing the RTC RAM, never set the jumpers. Setting the jumpers will cause system boot
failure!
If the steps above do not help, remove the on-board battery and place the jumper caps again to clear the
CMOS RTC RAM data. After clearing the CMOS, reinstall the battery.
You do not need to clear the CMOS when the system hangs due to overclocking. For system failure due to
overclocking, use the CPU Parameter Recall (C.P.R.) feature. Shut down and reboot the system, then the
BIOS automatically resets parameter settings to default values.
