Boards and Cards

General

The architecture of the PowerBook (FireWire) is designed around two

main circuit boards: the microprocessor board and the I/O logic board.

Besides the two main boards, the PowerBook (FireWire) can contain up to

seven cards: power supply card, sound card, RAM card (factory installed),

RAM card (user installed), AirPort Card, modem, and modem EMI filter.

AirPort Card

The AirPort Card transmits and receives data at up to 11 Mbps. Connecting

to the Internet or a wired local area network (LAN) requires a base station

as the connection to the Internet or a bridge between the wireless signals

and a wired LAN. Software included with the AirPort Card enables a

Macintosh computer that has an AirPort Card installed to act as a base

station.

In PowerBook (FireWire), the AirPort Card is installed under the

keyboard and above the PCMCIA Card slot.

PCMCIA (PC) Cards

The PCMCIA Card slot accepts one Type II card. The slot supports both 16-

bit PC Cards and 32-bit CardBus cards. Cards can be removed and replaced

while the computer is operating. The slot supports Zoomed Video on the

card connector.

To eject a PC card, first drag the PC Card icon (if present) to the trash.

Then push once on the eject button to release the button, and a second time

to eject the card.

The following are guidelines for properly handling PC Cards:

• Use only cards that are compatible with the PC Card unit. Refer to the
