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.
