Solutions to CD-ROM problems
Problems using the CD-ROM drive
The CD-ROM drive icon does not appear on screen.
m If you have other internal SCSI devices attached to your computer, make
sure that each device has a unique SCSI ID number (If your CD-ROM
drive was installed in your computer at the factory, it has SCSI ID 3.)
Refer to the documentation that came with your SCSI devices if you need
to reset SCSI ID numbers.
Note: Your computer also has an external SCSI connector. All devices on the
same SCSI chain must have unique ID numbers, but devices on different SCSI
chains may use the same SCSI ID number. (For example, you could have a
CD-ROM drive with ID number 3 connected to the internal SCSI chain and a
tape drive with ID number 3 connected to the external SCSI chain.
m If you installed a CD-ROM drive after you bought your computer, make
sure the CD-ROM software that came with the drive is installed. See the
manual that came with the CD-ROM drive for software installation
instructions.
m If you reinstall the CD-ROM software, make sure to restart your computer
after you reinstall the software.
You installed a CD-ROM drive after you bought your computer and your computer won’t
restart after you’ve copied software for your CD-ROM drive to the System Folder.
m If you attempt to install software for your CD-ROM drive without using the
Installer, you may not be able to restart your computer. Restart the
computer while holding down the Shift key (to turn off system extensions),
and then remove any CD-ROM software files you copied by dragging them
to the Trash. Reinstall the software according to the instructions that came
with the drive.
If this procedure doesn’t solve the problem, restart your computer using the
Disk Tools floppy disk. (For instructions on starting your computer using a
floppy disk, see “Starting Up From a Floppy Disk” in the section
“Initializing a Hard Disk,” later in this chapter.)
