Cache configurations
A High Performance Module (256K level 2 cache) provides an overall
increase in your computer’s performance. You can add a cache by having an
Apple-authorized dealer or service provider install a cache DIMM in the
cache slot on the main logic board of your computer.
Opening the computer
IMPORTANT
To avoid generating static electricity that may damage
components, do not walk around the room until you have completed the
installation of the expansion card or memory and closed the computer.
1
Shut down your computer by choosing Shut Down from the Special menu.
You can also press the Power key on the keyboard.
2
Unplug all the cables except the power cord from the computer—you’ll unplug the
power cord later. (Don’t forget to unplug the cable that connects your keyboard to
the computer.)
Leaving the power cord plugged in helps protect the computer from damage
caused by electrostatic discharge.
3
Unscrew and remove the three screws on the back of the computer.
Remove these three screws.
