- If you say Y here, your kernel will be able to manage low cost mass
- storage units such as ATA/(E)IDE and ATAPI units. The most common

-
- Integrated Disk Electronics (IDE aka ATA-1) is a connecting standard
- for mass storage units such as hard disks. It was designed by
- Western Digital and Compaq Computer in 1984. It was then named
- ST506. Quite a number of disks use the IDE interface.
-
- AT Attachment (ATA) is the superset of the IDE specifications.
- ST506 was also called ATA-1.
-
- Fast-IDE is ATA-2 (also named Fast ATA), Enhanced IDE (EIDE) is
- ATA-3. It provides support for larger disks (up to 8.4GB by means of
- the LBA standard), more disks (4 instead of 2) and for other mass
- storage units such as tapes and cdrom. UDMA/33 (aka UltraDMA/33) is
- ATA-4 and provides faster (and more CPU friendly) transfer modes
- than previous PIO (Programmed processor Input/Output) from previous
- ATA/IDE standards by means of fast DMA controllers.
-
- ATA Packet Interface (ATAPI) is a protocol used by EIDE tape and
- CD-ROM drives, similar in many respects to the SCSI protocol.
-
- SMART IDE (Self Monitoring, Analysis and Reporting Technology) was
- designed in order to prevent data corruption and disk crash by
- detecting pre hardware failure conditions (heat, access time, and
- the like...). Disks built since June 1995 may follow this standard.
- The kernel itself doesn't manage this; however there are quite a
- number of user programs such as smart that can query the status of
- SMART parameters from disk drives.
+ If you say Y here, your kernel will be able to manage ATA/(E)IDE and
+ ATAPI units. The most common cases are IDE hard drives and ATAPI
+ CD-ROM drives.
+
+ This subsystem is currently in maintenance mode with only bug fix
+ changes applied. Users of ATA hardware are encouraged to migrate to
+ the newer ATA subsystem ("Serial ATA (prod) and Parallel ATA
+ (experimental) drivers") which is more actively maintained.
