  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.

 105           There are two drivers for Serial ATA controllers.
 106
 107           The main driver, "libata", uses the SCSI subsystem
 108           and supports most modern SATA controllers. In order to use it
 109           you may take a look at "Serial ATA (prod) and Parallel ATA
 110           (experimental) drivers".
 111
 112           The IDE driver (which you are currently configuring) supports
 113           a few first-generation SATA controllers.
 114
 115           In order to eliminate conflicts between the two subsystems,
 116           this config option enables the IDE driver's SATA support.
 117           Normally this is disabled, as it is preferred that libata
 118           supports SATA controllers, and this (IDE) driver supports

 143           mode is a feature of most modern IDE hard drives, permitting the
 144           transfer of multiple sectors per Programmed Input/Output interrupt,
 145           rather than the usual one sector per interrupt. When this feature is
 146           enabled, it can reduce operating system overhead for disk Programmed
 147           Input/Output. On some systems, it also can increase the data
 148           throughput of Programmed Input/Output. Some drives, however, seemed
 149           to run slower with multiple sector mode enabled. Some drives claimed
 150           to support multiple sector mode, but lost data at some settings.

1026           There are two drivers for MFM/RLL/IDE hard disks. Most people use
1027           the newer enhanced driver, but this old one is still around for two
1028           reasons. Some older systems have strange timing problems and seem to
1029           work only with the old driver (which itself does not work with some
1030           newer systems). The other reason is that the old driver is smaller,
1031           since it lacks the enhanced functionality of the new one. This makes
1032           it a good choice for systems with very tight memory restrictions, or
1033           for systems with only older MFM/RLL/ESDI drives. Choosing the old
1034           driver can save 13 KB or so of kernel memory.
1035
1036           If you want to use this driver together with the new one you have
1037           to use "hda=noprobe hdb=noprobe" kernel parameters to prevent the new
1038           driver from probing the primary interface.
1039
1040           If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
1041           instead of this one. For more detailed information, read the
