NOTICE: When replacing the processor, do not touch any of the pins inside the
socket or allow any objects to fall on the pins in the socket.
8 Gently remove the processor from the socket.
9 If you are installing a new processor, leave the release lever extended in the
release position so that the socket is ready for the new processor. See
"Installing the Processor" on page 154.
Otherwise, continue with step 10.
NOTICE: The memory shroud holds the (optional) memory risers in place; its
thumbscrews must be sufficiently tight in order to secure the risers and to avoid
