    (ATA, AT Attachment or
   "Integrated Drive Electronics", IDE) A disk drive interface
   standard based on the IBM PC ISA 16-bit bus but also
   used on other personal computers.  ATA specifies the power
   and data signal interfaces between the motherboard and the
   integrated disk controller and drive.  The ATA "bus" only
   supports two devices - master and slave.

   ATA drives may in fact use any physical interface the
   manufacturer desires, so long as an embedded translator is
   included with the proper ATA interface.  ATA "controllers" are
   actually direct connections to the ISA bus.

   Originally called IDE, the ATA interface was invented by
   Compaq around 1986, and was developed with the help of
   Western Digital, Imprimis, and then-upstart Conner
   Peripherals.  Efforts to standardise the interface started in
   1988; the first draft appeared in March 1989, and a finished
   version was sent to ANSI group X3T10 (who named it "Advanced
   Technology Attachment" (ATA)) for ratification in November
   1990.

   X3T10 later extended ATA to Advanced Technology Attachment
   Interface with Extensions (ATA-2), followed by ATA-3 and
   ATA-4.
