motherboard, peripherals, and/or components.

1. Unplug the power cord from the wall socket before touching any

component.

2. To avoid damaging the motherboard components due to static elec-

tricity, NEVER place your motherboard directly on the carpet or the

like. Also remember to use a grounded wrist strap or touch a safety

grounded object before you handle components.

3. Hold components by the edges and do not touch the ICs.

4. Whenever you uninstall any component, place it on a grounded anti-

static pad or in the bag that comes with the component.

When placing screws into the screw holes to secure the mother-

board to the chassis, please do not over-tighten the screws! Doing

so may damage the motherboard.

What

HDCP?

HDCP stands for High-Bandwidth Digital Content Protection,

speci

cation developed by Intel

for protecting digital

entertainment content that uses the DVI interface. HDCP is a

copy protection scheme to eliminate the possibility of

intercepting digital data midstream between the video source,

or transmitter - such as a computer, DVD player or set-top box -

and the digital display, or receiver - such as a monitor, television

or projector. In other words, HDCP speci

cation is designed to

protect the integrity of content as it is being transmitted.

Products compatible with the HDCP scheme such as DVD

players, satellite and cable HDTV set-top-boxes, as well as few

entertainment PCs requires a secure connection to a compliant

display. Due to the increase in manufacturers employing HDCP

in their equipment, it is highly recommended that the HDTV or

LCD monitor you purchase is compatible.
