Electrostatic discharge (ESD) can damage your board, processor, disk
drives, add-in boards, and other components. Perform installation proce-
dures at an ESD workstation only. If such a station is not available, you
can provide some ESD protection by wearing an antistatic wrist strap
and attaching it to a metal part of the system chassis. If a wrist strap
