Keyboard and Trackpad
The keyboard and trackpad are the same design as those used in the earlier
PowerBook G3 Series of computers. The PowerBook (FireWire) keyboard
includes a built-in numeric keypad and controls to adjust display
brightness, speaker volume, and external audio port volume.
Several of the keys on the keyboard have more than one mode of operation.
These changes are controlled by the Fn key, the Num Lock key, and the
Function Keys checkbox in the Keyboard control panel.
FireWire Ports and Target Disk Mode
The PowerBook (FireWire) has two external FireWire ports. The ports:
• support serial I/O at up to 400 Mbps
• provide up to 6 watts of power when the computer is turned on
• accept external power input from the bus
• support starting up the system from a mass storage device
• support target disk mode
Target Disk mode is similar to SCSI Disk mode, except it uses a FireWire
connection. When the PowerBook is in Target Disk mode, the PowerBook
operates as a mass storage device. The two primary uses of this feature
are:
• high-speed data transfer between computers or devices
• diagnosis and repair of a corrupted internal hard drive
To put the PowerBook in Target Disk mode, press the T key while starting
up. To take the PowerBook out of Target Disk mode, press the power
button.
USB Ports
The PowerBook (FireWire) has two Universal Serial Bus (USB) ports

Basics
Boards and Cards
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 16bit 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
compatibility information that came with the PC Card. If you cannot
PowerBook (FireWire)
14
Boards and CardsBasics
find the compatibility information, contact the card vendor.
• Do not insert anything other than a PC Card into the card slots.
• The computer must be on or off to eject a PC Card. Do not eject a PC
Card when the computer is in sleep mode.
• Before you eject a card, make sure nothing is blocking the card’s slot.
• To use the card again immediately, pull it out about an inch more and
then push it back in. If you don’t follow this procedure and try to push
the card back in to use it again, the card will not engage properly.
• Do not pull on a PC Card before it has been ejected out of the slot.
Forcing a PC Card out of the slot may damage the computer or the card.
If the card is partially ejected, use pliers to carefully pull the card out
the rest of the way.
