[comp.sys.mac] How do software-switchable SCSI ID's work?

mouser@portia.Stanford.EDU (Michael Wang) (09/10/89)

Hi, I have a question for you SCSI experts out there. How do the drives
that allow you to change the SCSI ID for it in software (like DataFrames)
store that ID? Is it written on the drive itself, or is there something
like a EEPROM on the drive that stores that information?

Thanks for your help!

Michael,

Basically...the software (ie Manager) directs the controller to change the 
SCSI ID# and the controller does the rest and it stores this new information
on disk (which track ?).
