components. Electrostatic discharge will damage mainboard. Note that you must
take special precaution when handling the mainboard in dry or air-conditioned
environments.
The precaution below is to protect the mainboard from electrostatic discharge.
* Do not remove the anti-static packaging until you are ready to install the
mainboard and other system components.
* Ground yourself before removing any system component from its protective
anti-static packaging. To ground yourself, grasp the expansion slot covers or
other unpainted portion computer chassis.
* Frequently ground yourself while working ,or use a grounding strap.
* Handle the mainboard by the edges and avoid touching its components.
