Solutions to CD-ROM problems
Problems using the CD-ROM player
The CD-ROM player 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
player 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 player 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 player 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 player for software installation
instructions.
m If you reinstall the CD-ROM software, make sure to restart your computer
after you reinstall the software.
