and disconnect them.
3. Remove the mounting screw that secures the option board to
the chassis.
4. Remove the board by pulling it up and out of the expansion
slot connector.
5. Configure the jumpers and switches on the new board to
match those on the old board.

was removed. Make sure the board is firmly seated in the
connector(s) on the main logic board.
