44 Replacing and Adding System Components
To add an additional processor:
1 Turn off the system and disconnect the power cord, modem cord (if
installed), and all external peripheral devices.
2 Remove the left side cover panel. (See “Removing the side cover” on
page 18 and “Preventing static electricity discharge” on page 15.)
3 Hold the new processor over the empty processor socket and verify that
pin 1 on both the processor and the socket are aligned. Pin 1 is near the
marked corner.
4 Gently place the new processor into the socket.
5 Secure the processor by lowering the locking lever until the lever latches
into place. The processor will slip into place without pressure when
aligned correctly.
6 Install the heatsink. (See “To replace the heatsink:” on page 43.)
7 Connect the power supply cable of the processor fan to the second CPU
fan connector on the system board (See “System board” on page 6 for
location).
8 Close the case by following the instructions on page 20.
9 Reconnect the cords you removed, then turn on your computer.
10 Run the muloader.exe program that was included in the processor
upgrade kit in order to update the microcode table and enable the second
processor.
