board. Note the location of the ribbon cables for reassembly.
2. Remove the five screws that secure the controller board to the adapter board.
3. Squeeze the two sides of the standoff located in the center of the controller
board to unlatch the standoff while separating the two boards. There may be
some mechanical resistance felt from the two 96-pin interconnections
between the two boards.
