You can install printed circuit boards (called cards) for video and graphics
applications, networking and communications, additional processing power,
or other purposes. The cards fit into expansion slots inside the computer.
Your Macintosh has six expansion slots, each designed to accept a Peripheral
Component Interconnect (PCI) card. There is also an expansion slot that
contains the computer’s processor card. (The processor card can be upgraded
by replacing it with a more powerful processor card.)
IMPORTANT
Some cards may need to be installed by an Apple-authorized
service provider. Check the information that came with the card.
WARNING
If an expansion card requires an adapter, be sure to use the
adapter card designed specifically for your model of the computer.
Failure to do so could damage the card and your computer.
