Overview Of Jumper Settings - Viglen Vig644M Manual

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.
