Installing Adapters
6. Install the adapter:
a. Carefully grasp the adapter 2 by its top edge or upper
corners, and align it with the expansion slot on the system
board.
b. Press the adapter firmly into the expansion slot. The tapered
foot of the adapter-retaining bracket must fit into the mating
slot in the expansion-slot frame.
c. Align the rounded notch in the retaining bracket with the
threaded hole in the expansion-slot frame. The retaining
bracket fits into the space that was occupied by the slot
cover.
d. Insert the expansion-slot screw 1 that you removed in step
2a on page 147 into the threaded hole, and push the
rounded notch up against the screw.
e. Tighten the expansion-slot screw firmly (6.0 inch-pounds) on
the top of the adapter-retaining bracket.
