Symptom
You cannot start up or install from the Mac OS X Install CD-ROM disc. A broken folder icon or an alert box with this message may appear:
"An error occurred. Startup Disk was unable to select the install CD as the startup disk. (-2)"
Note: This does not affect USB-, SCSI-, or FireWire-based disc drives. Apple-installed ATA drives are factory-configured with ATA ID 0.
Solution
"Disc drive" refers to CD, CD-R, CD-RW, DVD, DVD-RAM, DVD-R, Combo drives, SuperDrives. Determine the ATA ID of your disc drive using Apple System Profiler.
1. Open the Apple System Profiler.
2. Click the Devices and Volumes tab.
3. Note the "ID=" information that is associated with your disc drive.
If you do not have access to Apple System Profiler, you will need to visually check jumper settings on your disc drive.

If the ATA ID is 1
Important: Resolving this issue requires opening your computer's case, physically removing the disc drive, moving one or two small jumpers on the drive, and putting the drive back in your computer. Instructions may have been included with your drive (if it was purchased separately from a third-party company) or appear in the materials which came with your computer.
The drive's ATA ID should be changed to ID 0 (master). Any other ATA device on the bus should need to be set to ATA ID 1. This is usually accomplished by adjusting jumpers on the back of the drive. Specific jumper setting information may be available from the manufacturer of the drive, or printed on the drive itself. If you use a third-party CD drive instead of the original Apple drive, you should also verify product compatibility with the manufacturer. If you need detailed assistance with changing the ID to 0 on a third-party device, refer to the manufacturer of the drive or their Web site.
Note: You should not change your Apple-installed disc drive to ATA ID 1 (slave mode) when adding other ATA devices.
