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 areasthis 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.

DDR3 1333MHz and DDR3 1066MHz SDRAM DIMMs
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.
Memory Configurations
The Intel Core i7, Intel Core i5, Intel Core i3, and Intel Pentium processors support the
following types of memory organization:

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

Real-Time Clock, CMOS SRAM, 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 autoconfiguration 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 Conventional PCI or 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. A supervisor 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
supervisor password or the user password to access Setup. Setup options are then
V1.0
Vig644M Motherboard Manual
12
available for viewing and changing depending on whether the supervisor 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 supervisor 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.

Vig644M Motherboard Manual
16
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 Vig644M motherboard contains the latest technology to offer an almost jumperless
configuration. All Intel® Core 2 Quad and Core 2 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.

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.
To replace the battery, carry out the following:
Observe the precautions in “Before You Begin.”
Turn off all peripheral devices connected to the system.
Turn off the system.
Remove any components that are blocking access to the battery.
Figure 29, 1 shows the battery location. Gently pry the battery free from its socket,
taking care to note the "+" and "-" orientation of the battery (Figure 29, 2).

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 5: Resetting the System
To do the following
Soft boot: Clear the system memory and
reload the operating system (also called
warm reset).
Press
<Ctrl + Alt + Del>
Cold boot: Clear the system memory, halt Power off/on or reset button (at front
power to all peripherals, restart POST, and of the system)
reload the operating system.

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

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.
