Caution
If you insert the math coprocessor in the wrong position, you could permanently damage it and destroy the components on the main system board.
7.Set the coprocessor on the socket and line up all of the pins on the coprocessor with the holes in the socket. Then gently push the coprocessor into the socket, pressing evenly on both ends, as shown below.
If the coprocessor does not go in smoothly, do not force it; pull it all the way out and try again, keeping it straight as you insert it. Examine the coprocessor to be sure it is inserted all the way into the socket.
8.Replace the subassembly. See page
