Note:
Trusted Platform Module (TPM)
The D925XCV motherboard incorporates the TPM “Trusted Platform Module”.
The Trusted Platform Module is a component on the desktop board that is specifically
designed to enhance platform security above-and-beyond the capabilities of today’s
software by providing a protected space for key operations and other security critical tasks.
Using both hardware and software, the TPM protects encryption and signature keys at their
most vulnerable stages — operations when the keys are being used unencrypted in plain-
text form. The TPM is specifically designed to shield unencrypted keys and platform
authentication information from software-based attacks.
Warning of Potential Data Loss!
The D925XCV motherboard incorporates the TPM “Trusted Platform
Module” this is disabled by default in the BIOS setup utility please
refer to the accompanied D925XCV motherboard manual.pdf,
TPMQuickReference.pdf and TPMFlyer.pdf.

Upgradingand ESD precautions
WARNING
Unplug the system before carrying out the procedures described in this document. 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 proceed 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 Eor 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 Nor
coloured black.
The wire which is coloured brown must be connected to the terminal which is marked with the letter Lor
coloured red.
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.
CAUTION!
The Viglen D925XCV motherboard
and associated components are
sensitive electronic devices. A small
static shock from your body can
cause expensive damage to your
equipment.

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.

This goes to the Hard Disk L.E.D. on the front panel, which lights up when the IDE Hard Disk is in use.
B - Reset switch connector
When these pins are shorted, it will cause the computer to perform a cold reboot.
C - Power L.E.D.
This attaches to the power L.E.D on the front panel, to display if the computer is active or not.
D- Power On/Off
When these pins are shorted it turns the computer on and off.

•Jumpersettings
CAUTION Do not move any jumpers 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.
Figure 5. Motherboard jumper.
BIOS Setup Configuration Jumper (J6J3) Settings
The 3-pin jumper block determines the BIOS Setup program's mode. The table below describes the jumper settings for the three
modes: normal, configure, and recovery. When the jumper is set to configure mode and the computer is powered-up, the BIOS
compares the processor version and the microcode version in the BIOS and reports if the two match.
Table 4.
Function/Mode Jumper Setting Configuration
Normal 1-2 The BIOS uses current configuration information and passwords for booting.
Configure 2-3 After the POST runs, Setup runs automatically. The maintenance menu is
displayed.
Recovery None The BIOS attempts to recover the BIOS configuration. A recovery diskette is
required.
