Make sure the socket 478 lever is in the upright position. To
raise the lever, pull it out to the side a little and raise it as far
as it will go.
Place the CPU in the empty socket. Follow the instructions
that came with the CPU. If you have no instructions,
complete the following procedure. Carefully align the CPU
so it is parallel to the socket and the notches on the corners
of the CPU correspond with the notches on the inside of the
socket. Gently slide the CPU in. It should insert easily. If it
does not insert easily, pull the lever up a little bit more.
