12.3 Apple Macintosh
Symptoms
•
Invalid Drive Specification
•
No Device Found
•
Drive Not Responding
Possible Cause and Solution
SCSI Address Conflicts With the Hard Disk Drive
This usually can be corrected by selecting another SCSI address (normally addresses 1 to
6) for your CD-ROM drive. Note: the Macintosh’s hard disk uses address 0 and its
internal SCSI adapter uses address 7.
Symptom
•
Computer Does Not Respond
Possible Cause and Solution
INIT Conflicts
Remove all INITs except those absolutely needed from your System Folder and the
ones copied from the CD-ROM device driver disk. If the CD-ROM drive functions
correctly, reinstall the INITs one at a time, restarting the Macintosh after each one,
until the problem is solved.
Symptom
•
Low Performance of CD-ROM Application Software
Possible Cause and Solution
System Set for Virtual Memory
If your Macintosh is using System 7 and is in Virtual Mode, it may exhibit slow performance
during real-time graphics and animation. This is because your hard disk drive and
CD-ROM drive must use your computer’s SCSI bus almost simultaneously. To remedy
this, remove Virtual Mode from the system and restart the Macintosh.
