          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.

          To compile this driver as a module, choose M here: the
          module will be called ide.

          For further information, please read <file:Documentation/ide/ide.txt>.

          disk/cdrom/tape/floppy drives.

          Multi-Disk-HOWTO, available from
          <http://www.tldp.org/docs.html#howto>.

          To fine-tune ATA/IDE drive/interface parameters for improved
          performance, look for the hdparm package at

          one containing the directory /) is located on an IDE device.

          If you have one or more IDE drives, say Y or M here. If your system
          has no IDE drives, or if memory requirements are really tight, you
          could say N here, and select the "Old hard disk driver" below
          instead to save about 13 KB of memory in the kernel.

          There are two drivers for Serial ATA controllers.

          The main driver, "libata", uses the SCSI subsystem
          and supports most modern SATA controllers. In order to use it
          you may take a look at "Serial ATA (prod) and Parallel ATA
          (experimental) drivers".

          this config option enables the IDE driver's SATA support.

          kernel or loaded before other ATA (IDE or libata) drivers
          and the controller is located at legacy ports, this driver
          may grab those ports and thus can prevent the controller
          specific driver from attaching.

          Also, currently, IDE generic doesn't allow IRQ sharing
          meaning that the IRQs it grabs won't be available to other
