If you have a computer with SCSI (Small Computer System Interface) devices, make sure each device has a unique ID number, from 0 to 7. Internal SCSI devices typically have the following ID numbers:

	Internal device		ID
	Hard disk		0
	CD-ROM drive		3
	Zip drive		5
	Macintosh computer		7

Note: Some computers have two separate SCSI chains, each with its own set of ID numbers. Some computers have ATA or IDE hard disk drives, which do not have SCSI ID numbers. See the setup instructions and technical information that came with your computer.

Make sure that the SCSI chain is properly terminated. Usually, the first and last device of each SCSI chain must be terminated.

See the documentation that came with your computer and SCSI equipment for specific details on setting SCSI ID numbers and terminating SCSI devices.
