  14           If you say Y here, your kernel will be able to manage low cost mass
  15           storage units such as ATA/(E)IDE and ATAPI units. The most common
  16           cases are IDE hard drives and ATAPI CD-ROM drives.
  17
  18           If your system is pure SCSI and doesn't use these interfaces, you
  19           can say N here.
  20
  21           Integrated Disk Electronics (IDE aka ATA-1) is a connecting standard
  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.
  28
  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.
  39
  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.

  69           There are two drivers for Serial ATA controllers.
  70
  71           The main driver, "libata", uses the SCSI subsystem
  72           and supports most modern SATA controllers. In order to use it
  73           you may take a look at "Serial ATA (prod) and Parallel ATA
  74           (experimental) drivers".
  75
  76           The IDE driver (which you are currently configuring) supports
  77           a few first-generation SATA controllers.
  78
  79           In order to eliminate conflicts between the two subsystems,
  80           this config option enables the IDE driver's SATA support.
  81           Normally this is disabled, as it is preferred that libata
  82           supports SATA controllers, and this (IDE) driver supports
  83           PATA controllers.

 240           This is the generic IDE driver.  This driver attaches to the

 242           so on).  Please note that if this driver is built into the
 243           kernel or loaded before other ATA (IDE or libata) drivers
 244           and the controller is located at legacy ports, this driver
 245           may grab those ports and thus can prevent the controller
 246           specific driver from attaching.
 247
 248           Also, currently, IDE generic doesn't allow IRQ sharing
 249           meaning that the IRQs it grabs won't be available to other
 250           controllers sharing those IRQs which usually makes drivers
