Basics CD-ROM and Hard Drive Interface - 8
CD-ROM and Hard Drive Interface
The internal hard drive uses intelligent device electronics
(IDE) technology, commonly used in DOS-compatible
systems. The IDE drive uses the standard advanced
technology attachment (ATA) or IDE interface. The IDE hard
drive functions the same as a typical SCSI hard drive. You
must replace IDE drives like for like. The IDE drive does not
affect SCSI ID selections or SCSI termination schemes. Seven
external SCSI devices may be daisy-chained through the
external SCSI port.
The CD-ROM drive uses the advanced technology adapter
peripheral interface (ATAPI), not SCSI. The ATA and ATAPI
interface schemes could be incompatible with some disk
utility programs.
