PowerBook G3 (Bronze Keyboard) computers with Mac OS 9.2, 9.2.1, or 9.2.2 may unexpectedly use SCSI ID 0 when starting in SCSI Disk Mode. The PowerBook hard disk will not appear or be available to the host computer because the internal SCSI hard drive also uses SCSI ID 0.
Symptom
The PowerBook unexpectedly uses SCSI ID 0 when starting up in SCSI Disk Mode and does not appear on, or become available to, the host computer.
Products Affected
Solution
Prior to starting up in SCSI Disk Mode, use the PowerBook SCSI Setup control panel and set the SCSI ID to 6. This will result in the PowerBook using SCSI ID 5 instead of 0. The hard disk will be available to the host computer as long as SCSI ID 5 is not in use by another device in the SCSI chain.
Important: Only SCSI ID 6 may be used as a workaround.
