Installation
You should now have identified the upgrade socket, and
ensured that it does not have a processor in it. You are
ready to install your new upgrade processor.
1. The upgrade processor and socket are keyed to
ensure that the processor can only be installed in
one orientation.
The inside of one corner of the socket has a key
hole, the outside of the same corner is missing three
holes. The processor has a positioning guide in the
form of a small dot of paint. Use the following
illustration to help identify these features.
