4. Remove the cache memory chips in sockets U33-U36and
U4N43. Use a chip remover or wedge a small screwdriver
between the sockets and the chips until you can remove the
chips.
5. Inspect each cache memory chip you are going to install; the
pins should point inward at slightly less than a 90
o
angle. If
any of the pins are bent or crooked, straighten them gently
with your fingers or with small tweezers to align them with
the other pins. Be careful when you do this; the pins are
fragile and can break off easily.
6. Position one of the cache chips over the first socket as shown
below, aligning the pins on the chip with the holes in the
socket. Align the small notch on the end of the chip with
the corresponding notch on the socket.

Gently press the chip halfway into the socket (to make sure
it is correctly aligned). If the chip goes in at an angle,
remove it and try again.
When the chip is properly positioned, push down firmly on
both ends of the chip to make sure it is well-seated.
Repeat steps 5 through 7 for each of the remaining chips.
