Gently press the chip halfway into the socket (to make sure
it is correctly aligned). If the chip does not go in smoothly,
remove it and try again.
When the chip is properly positioned, push down firmly on
both ends to make sure it is well-seated.
Repeat steps 4 through 6 for each of the remaining chips.
Replace any option cards you removed. See page 3-14 for
instructions.
