As an aside, Macs don't care about SCSI ID very much since they name 
each volume (mountable paritition) on a drive.  The equivalent of root, 
the System Folder, is selected from the volume marked as the "Startup 
Disk" in a control panel.  SCSI IDs can be shuffled around without 
screwing it up (althouth not without shutting it off and rebooting).  
Volumes can be renamed at any time, so internally it maintains pointers 
to volume tables which then contain the names and pointers to SCSI IDs 
and other whatnot.
