NVRAMs to the new board.
When installing a new controller board
1. Install the NVRAM from the old controller board on a new controller board.
2. Install the new controller board in the machine.
3. Disconnect the cables of the HDD from the controller board if the HDD option has already been
installed.
 Disconnecting the cables of the HDD is very important. Otherwise, the HDD is
automatically formatted and all data in the HDD is lost due to the security limitation.
4. Reassemble the machine.
5. Turn on the main power of the machine.
 If the HDD option has not been installed, the installation procedure is completed.
 If the HDD option has already been installed, go to next step.
6. Turn off the main power of the machine, and then connect the cables of the HDD again.
 Make sure you print out the SMC reports ("SP Mode Data" and "Logging Data") before
you replace the NVRAM.
 Keep NVRAMs away from any objects that can cause static electricity. Static electricity
can damage NVRAM data.
 Make sure the NVRAM is correctly installed on the controller board.
