22 for mass storage units such as hard disks. It was designed by
23 Western Digital and Compaq Computer in 1984. It was then named
24 ST506. Quite a number of disks use the IDE interface.
25
26 AT Attachment (ATA) is the superset of the IDE specifications.
27 ST506 was also called ATA-1.

29 Fast-IDE is ATA-2 (also named Fast ATA), Enhanced IDE (EIDE) is
30 ATA-3. It provides support for larger disks (up to 8.4GB by means of
31 the LBA standard), more disks (4 instead of 2) and for other mass
32 storage units such as tapes and cdrom. UDMA/33 (aka UltraDMA/33) is
33 ATA-4 and provides faster (and more CPU friendly) transfer modes
34 than previous PIO (Programmed processor Input/Output) from previous
35 ATA/IDE standards by means of fast DMA controllers.
36
37 ATA Packet Interface (ATAPI) is a protocol used by EIDE tape and
38 CD-ROM drives, similar in many respects to the SCSI protocol.

40 SMART IDE (Self Monitoring, Analysis and Reporting Technology) was
41 designed in order to prevent data corruption and disk crash by
42 detecting pre hardware failure conditions (heat, access time, and
43 the like...). Disks built since June 1995 may follow this standard.
44 The kernel itself doesn't manage this; however there are quite a
45 number of user programs such as smart that can query the status of
46 SMART parameters from disk drives.
