Read this chapter for

information on using expansion

bay modules and PC Cards.

Using expansion bay modules

The floppy disk drive and the CD-ROM drive for your Macintosh PowerBook
are removable modules, which you can easily switch or replace with another
module. The place in your computer where modules go is called the

expansion

bay. (The floppy disk drive is installed in the expansion bay at the factory.)

You can switch the modules, such as the floppy disk drive, CD-ROM drive or
PC Card storage case, or remove a module while the PowerBook is turned on,
in sleep, or shut down. All expansion bay modules are inserted and removed
in the same way.

To protect your work and to be sure that the computer recognizes which
module is in use, first quit any programs that may be using files on the disk i n
that module. T hen select the disk’s icon and choose Put Away from the File
menu or drag the icon to the Trash.

IMPORTANT

Don’t switch modules while the computer is starting up. Also take
care not to remove a module if a floppy disk or CD-ROM disc is inserted and
in use.

If you purchase an expansion bay module from an independent supplier, b e
sure to follow the instructions that came with the device. Some modules may
have special requirements, such as shutting down the computer before
inserting or removing the module. At least one manufacturer makes an
internal power adapter for use in the expansion bay.

2

Using Expansion Bay Modules and PC Cards

Removing an expansion bay module

To remove a n expansion bay module from your Macintosh PowerBook, follow
these steps:

1 Quit any application programs or files that are using the floppy disk or compact disc

(CD) or other medium inserted in the expansion bay module.

Remember to save your work.

2 If a floppy disk or CD is inserted in the module, click its icon to select it and drag its icon

to the Trash (or choose Put Away from the File menu).

You should not remove the module if a disk is in use. If you have any other
kind of optional expansion bay module, make sure you drag the icon for its
media to the Trash or select the icon and choose Put Away from the File menu.

3 Unlock the expansion bay module by sliding the module release latch on the bottom of

your Macintosh PowerBook in the direction of the arrow.

To unlock the module, slide the latch
on the underside of the computer.

16

Chapter 2

4 Hold the module by the gripping surface and pull it out of the computer.

IMPORTANT

You should not remove an expansion bay module if it is in use or
you may lose data. If you try to remove the module when it is in use, you’ll
see a message telling you to reinsert it. Reinser t the module, quit any files or
programs that may be using the floppy disk (or other medium inserted i n the
module), then select the disk’s icon and choose Put Away from the File menu
or drag the disk’s icon to the Trash. (If the module contains the startup disk,
you can’t remove the module or drag the disk to the Trash.)

To be sure that you don’t get another in-use message, wait 5 seconds after
quitting programs and ejecting a disk before you remove the module.

If you put your computer to sleep while a floppy disk or other medium is
inserted, the green i n-use light to the left of the module will flash (similar to
the sleep indicator light on your computer’s display). You should not remove
the module while the in-use light is on or flashing.

Hold the module by the gripping surface
and pull it completely out of the computer.

The module release latch automatically slides back
into its proper position as you remove the module.

Gripping surface

17

Using Expansion Bay Modules and PC Cards

Inserting an expansion bay module

To reinsert the expansion bay module, slide the module in. Make sure the
gripping surface is facing down. The release button automatically returns to
the locked position.

Be sure the module is completely inserted. If it does not insert properly, reset
the module release latch to the unlocked position (as in step 3 earlier) before
reinserting the module.

The expansion bay can use a wide component, such as the 5.25-inch CD-ROM
drive, or a narrower component, such as the 3.5-inch floppy disk drive. When
a narrower device is in the expansion bay, a small flap covers the empty part of
the bay. When a wider drive is inserted, the flap folds into the bay.

Note: A plastic storage case for PC Cards is provided with your PowerBook.
This case fits into the expansion bay. If you want to make the computer as
light as possible, you can remove the module in the expansion bay and insert
the PC Card storage case. Always keep a module or the PC Card storage case
in the expansion bay to protect the connectors inside the bay.

Using a CD in the CD-ROM drive

You i nsert or remove the CD-ROM drive in the same way as any other module.

Inserting a disc

To load a compact disc in the drive, follow these steps:

1 Start up the PowerBook, if it’s not already on.
2 Press the Open button on the outside of the CD-ROM module to open its tray.

The tray opens part way.
(If the tray doesn’t open, a disc may already be in the drive. Drag its icon to the

Trash to open the tray. You’ll see a message if the disc is in use; in that case,
quit the program in use or close the disc’s window if no program is in use.)

3 Pull the tray all the way open and place a CD-ROM disc in the tray, with the label facing up.

Make sure the disc is lying flat in the tray and is seated firmly on the spindle.
Avoid touching the drive’s lens.

Insert the disc,
label side up.

19

Using Expansion Bay Modules and PC Cards

4 Push the tray in to close it.

When the CD-ROM drive is in use, you may notice some vibration and noise
as the compact disc spins rapidly. Certain discs can cause the drive to vibrate
because they have heavily inked artwork or a label that creates an imbalance.

Variations in speed of CDs is normal. Different types of disks run at different
speeds; for example, audio CDs all r un at a low speed.

The high-speed CD-ROM drive for your PowerBook contains an intelligent
sensor that detects an unbalanced disc and adjusts the disc speed to minimize
vibration. Even when the speed changes, the CD still functions normally, but
it may transfer information at a somewhat slower rate.

Some vibration is not unusual for a high-speed CD-ROM drive, in part
because there is no specification for balance of compact discs. To mi nimize
vibration from unbalanced compact discs, do not put labels on your CDs.
Place the computer on a flat, solid surface when using the CD-ROM drive.

Keep the CD-ROM drive’s tray closed except when loading discs. This
prevents dust from getting inside the mechanism. Also be sure to keep the
CD’s recorded surface (the side opposite the label) free of contamination such
as fingerpri nts, dust, and grease. T he performance of the drive depends on
the optical quality of the CD media.

Chapter 2

Ejecting a disc

Follow these instructions to open the tray and eject a CD-ROM disc from
the drive:

1 Open the tray.

There are several ways to open the tray of your CD-ROM drive.

If a CD-ROM disc icon appears on your screen, do one of the following:

m Select the disc icon on your screen and drag the icon to the Trash.
m Click the disc icon and choose the Put Away command i n the File menu.
m While the CD player’s window is active, choose Eject CD from the File

menu, or simultaneously press the x and E keys. (Do not remove the
module if you use this method of ejecting the disc.)

m Use the pop-up menu in the CD section of the Control Strip to eject a CD.

If no CD-ROM disc icon appears on your screen, do this:

m Press the Open button on your CD-ROM drive.

2 Take the disc out of the tray.

Store your disc in a safe place, away from heat, dust, and moisture.

3 Push the tray in to close it.

To avoid possible damage to the tray or the drive, keep the tray closed when
you are not using it.

21

Using Expansion Bay Modules and PC Cards

If you still can’t eject a disc, try this method:

If the standard methods of ejecting a CD do not work (or the computer is
shut down), you can eject the disc manually. Carefully insert the end of a
straightened paper clip into the small hole near the CD-ROM drive’s opening,
and push firmly until the tray disengages. Pull the tray open, remove the disc,
and close the tray.

Insert the end of a
large, straightened
paper clip into
this hole.

Using Expansion Bay Modules and PC Cards

Using PC Cards (PCMCIA cards)

PC Cards (also known as PCMCIA cards) are about the size of a thick credit
card and have a 68-pin connector at one end. They come in many varieties,
such as fax/modem cards, mass-storage cards, Ethernet connection cards, and
wireless communication cards. You can use PC Cards to expand your
Macintosh PowerBook’s capabilities.

This section describes how to insert and eject PC Cards and how to set up
your communications software to use PC Card modems. For information on
using PC Cards, see the “Using PC Cards” topic area of Mac OS Help,
available in the Help menu.

Your Macintosh PowerBook has two PC Card slots: an upper slot and
a lower slot. You can insert a card into either slot, or you can use both
slots simultaneously.

There are three types of PC Cards. T h e different types refer to the thickness
of the card. A Type I card is 3.3 millimeters (mm) thick, a Type II card is
5 mm thick, and a Type III card is 10.5 mm thick. Make sure you check the
documentation that came with your PC Card to verify that it is compatible
with your Macintosh PowerBook.

You can place a Type I or Type II card in either the upper or lower slot. You
can place a Type III card only in the lower slot. When a Typ e III card is in the
lower slot, you cannot use the upper slot. You may find it useful to get in the
habit of always using the lower slot to make sure the card you are using is
properly inserted.

A special type of PC Card supports “Zoomed Video,” a method of showing
full-motion video images in a window on the computer’s screen. Your
PowerBook is designed to use a Zoomed Video card, but this type of card
must be placed in the lower PC Card slot.

WARNING

Make sure you only use cards that are designated by the PC
Card manufacturer as compatible with your Macintosh PowerBook. If
you use an incompatible card, you may damage the card or your
PowerBook. If you are not sure whether a PC Card is compatible with
your PowerBook, contact the PC Card manufacturer.

24

Chapter 2

Inserting a PC Card

To insert a card, do this:

m

Insert the card, connector first and label up, into the slot. Make sure the card is level.

A Type III PC Card or a
Zoomed Video card must be
inserted in the lower slot.

A Type I or Type II PC Card can be
inserted in either the upper or lower slot.

25

Using Expansion Bay Modules and PC Cards

You’ll feel some resistance as you slide the card in. When the card is firmly
seated, you will feel it click into place. Consult the card’s documentation for
details of its use.

An icon for the PC Card appears on the desktop.
You are now ready to use the card.

Ejecting a PC Card

Your computer must be on or off to eject a PC Card. You cannot eject a PC
Card when the computer is in sleep.

IMPORTANT

Before you eject a card, make sure that nothing is blocking the
card’s slot. If you want 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 you
try to push the card back in to use it again, the card will not engage properly.)

To eject a PC Card when the computer is on, follow these steps:

1 If the computer is in sleep, press the Power key (or any key on the keyboard except Caps

Lock) to wake it.

2 Click the PC Card’s icon to select it.
3 Choose Put Away from the File menu.
4 Pull the card out of the slot.

IMPORTANT

2 Insert the end of the straightened paper clip into the hole next to the slot that contains

the card, and press gently but firmly until the card is ejected.

3 Pull the card out of the slot.

Setting the computer not to eject storage PC Cards at startup

If a you have a storage PC Card, such as an SRAM card or an ATA hard disk,
in either slot, the card will be ejected when the computer starts up. To prevent
excessive wear on PC Card connectors and slots, you can use the Startup Disk
control panel to keep storage PC Cards from ejecting when you turn on the
computer. (Other typ es of PC Cards, such as a modem or Ethernet card, are
not ejected at startup.)

Follow these steps to avoid having a storage PC Card eject at startup:

1 Open the Startup Disk control panel.

If you need instructions for opening the control panel, see “How do I make a
disk the startup disk?” in the Disks topic area of Mac OS Help, available in
the Help menu.

2 Click the icon for the computer’s hard disk to select it.

If you can’t eject a card, insert
the end of a straightened paper
clip into the hole next to the slot.
This hole is for the upper slot.

This hole is for the lower slot.

3 Close the control panel.

The PC Card storage device will no longer eject at startup.

Using a Zoomed Video PC Card

The lower PC Card s lot in your Mac int osh PowerBook has circuitry for handling
vi deo signals, called “Zoomed Video. ” Some independent manufacturers off er PC
Cards to which you can provide a video signal or connect a video camera. The
Zoomed Video PC Card is a Type II card; it can only be used in the lower slot
(because the special circuitry needed for video signals is located in that slot).

With a Zoomed Video card in the lower PC Card slot, the PowerBook ca n
display video on the computer’s screen or on an external monitor. Video
signals are sent directly to the video controller, so that the computer can
display full-motion video while performing other tasks at the same time.

If you purchase a Zoomed Video PC Card, be sure that it has software that
works with your PowerBook.

Using a PC Card modem

When you are using a PC Card modem, make sure you do the following:

1 Install the communications software you want to use, as well as any software that came

with your modem.

See the documentation that came with your modem and your communications
software for instructions on setting up a PC Card modem for each application.
Check to see if PC Card modem files for your software were included. You
can get other modem files from the manufacturer of your modem or your
communications software.
