Read this chapter for
information on using expansion
bay modules and PC Cards.
Using expansion bay modules
The floppy disk drive and the optional CD-ROM drive in 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 and CD-ROM
drive, 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 in
that module. Then 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 is inserted and
in use.
If you purchase an expansion bay module from an independent supplier, be
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.
