For More Information on FireWire

Additional information on FireWire is available in Mac OS Help. Choose

information on the Apple FireWire website at www.apple.com/firewire.
PC Cards
You can expand your computer’s capabilities using the PC Card slot. You can connect
hard drives, compact Flash card readers, and more. Your PowerBook has one PC Card
slot that accepts Type I and Type II PCMCIA cards, including CardBus-format cards. You
can insert a PC Card when your computer is on, off, or in sleep.
Important: The Apple AirPort Extreme Card is installed in a slot inside the computer.
It doesn’t go in the PC Card slot the way many third-party wireless cards do. The AirPort
Extreme Card will not work if it is installed in the PC Card slot and will cause your
computer to function improperly.

Inserting and Ejecting a PC Card

When inserting a PC Card, make sure the label is facing up and the card is level. You’ll
feel some resistance as you slide the card in. When the card is firmly seated in the slot,
it clicks into place and an icon may appear on the desktop. You can eject a PC Card
when your computer is on or off, but not when it is in sleep.
