ESD Precautions
Computer boards have integrated circuits sensitive to static electricity.
To prevent chipsets from electrostatic discharge damage, please take
care of the following jobs with precautions:
Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
Before holding the board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. It
discharges static electricity from your body.
Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.
