NOTICE: You must position the microprocessor module correctly in the ZIF
socket to avoid permanent damage to the module and the socket.
When the microprocessor module is correctly seated, all four corners
are aligned to the same height. If one or more corners of the module
are higher than the others, the module is not seated correctly.
NOTICE: Hold the microprocessor down while turning the cam screw to
prevent intermittent contact between the cam screw and microprocessor (see
