Apple Power Macintosh 4400 - Manual (Page 130)

CD-ROM software is already installed on Macintosh computers that come
with CD-ROM drives. You can reinstall it by reinstalling your system
software, following the instructions in Chapter 8, “Reinstalling Your
Computer’s Software.”
m Make sure that the Apple CD-ROM extension is turned on in the
Extensions Manager control panel. Open the Extensions Manager control
panel in the Control Panels folder in the Apple (K) menu. Click to put a
checkmark next to Apple CD-ROM, then restart your computer.
m If you installed the CD-ROM drive after you bought your computer, make
sure the CD-ROM software is installed. Refer to the documentation that
came with the CD-ROM drive. (The CD-ROM software is already installed
on Macintosh computers that come with CD-ROM drives.)
Your computer displays the message “This is not a Macintosh disk: Do you want to
initialize it?” when you insert a CD-ROM disc in the CD-ROM drive.
m Make sure that the Foreign File Access and Audio CD Access CD-ROM
extensions are installed and turned on. You can find them in your
Extensions folder in the System Folder on your hard disk. If they are not
turned on, use the Extensions Manager control panel in the Control Panels
folder in the Apple (K) menu to turn them on. (Click to put checkmarks
beside them.) Then restart your computer.
m Make sure the CD-ROM software is installed. (The CD-ROM software is
already installed on Macintosh computers that come with CD-ROM drives.)
If you installed a CD-ROM drive after buying your computer, see the
manual that came with the drive.
m The disc may use a format that the Macintosh cannot recognize. Ask the
disc’s manufacturer for a disc that a Macintosh can recognize.
Your computer ejects a CD-ROM disc without giving you any error message.
m Make sure the disc is flat in the tray and the disc label is facing up.
IMPORTANT If you’re using a small (8 cm) disc, make sure it’s centered
within the tray’s inner ring and the computer is absolutely level. An
improperly seated small disc in your computer may result in damage to
the disc, the CD-ROM drive, or both.
