-          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
-          cases are IDE hard drives and ATAPI CD-ROM drives.
-
-          If your system is pure SCSI and doesn't use these interfaces, you
-          can say N here.
-
-          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.
 
           To compile this driver as a module, choose M here: the
           module will be called ide-core.
 
           For further information, please read <file:Documentation/ide/ide.txt>.
 
-          If unsure, say Y.
