13. Remove all heat sinks and microprocessors from the old system board and
install them on the new system board using the microprocessor installation
tool (see "Removing a microprocessor and heat sink" on page 349).
Note:
a. Be sure to keep the heat sink and microprocessor from each
microprocessor socket of the old system board together so that you can
install them on the new system board together. For example, when you
remove the heat sink and microprocessor from microprocessor socket 1 of
the old system board , install them both on the same socket on the new
system board.
b. Use an alcohol wipe to remove any thermal grease from the tabs on the
microprocessor bracket frame on the old system board.
14. Remove the socket covers from the microprocessor sockets on the new system
board and place them on the microprocessor sockets of the old system board
that you are removing. The microprocessor socket might have the socket cover
style shown in illustration A or the style shown in illustration B.
