  16           If you say Y here, your kernel will be able to manage low cost mass
  17           storage units such as ATA/(E)IDE and ATAPI units. The most common
  18           cases are IDE hard drives and ATAPI CD-ROM drives.
  19
  20           If your system is pure SCSI and doesn't use these interfaces, you
  21           can say N here.
  22
  23           Integrated Disk Electronics (IDE aka ATA-1) is a connecting standard
  24           for mass storage units such as hard disks. It was designed by
  25           Western Digital and Compaq Computer in 1984. It was then named
  26           ST506. Quite a number of disks use the IDE interface.
  27
  28           AT Attachment (ATA) is the superset of the IDE specifications.
  29           ST506 was also called ATA-1.
  30
  31           Fast-IDE is ATA-2 (also named Fast ATA), Enhanced IDE (EIDE) is
  32           ATA-3. It provides support for larger disks (up to 8.4GB by means of
  33           the LBA standard), more disks (4 instead of 2) and for other mass
  34           storage units such as tapes and cdrom. UDMA/33 (aka UltraDMA/33) is
  35           ATA-4 and provides faster (and more CPU friendly) transfer modes
  36           than previous PIO (Programmed processor Input/Output) from previous
  37           ATA/IDE standards by means of fast DMA controllers.
  38
  39           ATA Packet Interface (ATAPI) is a protocol used by EIDE tape and
  40           CD-ROM drives, similar in many respects to the SCSI protocol.
  41
  42           SMART IDE (Self Monitoring, Analysis and Reporting Technology) was
  43           designed in order to prevent data corruption and disk crash by
  44           detecting pre hardware failure conditions (heat, access time, and
  45           the like...). Disks built since June 1995 may follow this standard.
  46           The kernel itself doesn't manage this; however there are quite a
  47           number of user programs such as smart that can query the status of
  48           SMART parameters from disk drives.

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

 129           There are two drivers for MFM/RLL/IDE disks.  Most people use just
 130           the new enhanced driver by itself.  This option however installs the
 131           old hard disk driver to control the primary IDE/disk interface in
 132           the system, leaving the new enhanced IDE driver to take care of only
 133           the 2nd/3rd/4th IDE interfaces.  Doing this will prevent you from
 134           having an IDE/ATAPI CD-ROM or tape drive connected to the primary
 135           IDE interface.  Choosing this option may be useful for older systems

 163           mode is a feature of most modern IDE hard drives, permitting the

 165           rather than the usual one sector per interrupt. When this feature is
 166           enabled, it can reduce operating system overhead for disk Programmed
 167           Input/Output. On some systems, it also can increase the data
 168           throughput of Programmed Input/Output. Some drives, however, seemed

 170           to support multiple sector mode, but lost data at some settings.

 408           Normally, IDE controllers built into the motherboard (on-board

 410           cards (off-board controllers) are relegated to ide2 and ide3.
 411           Answering Y here will allow you to reverse the situation, with

1137         help
1138           There are two drivers for MFM/RLL/IDE hard disks. Most people use
1139           the newer enhanced driver, but this old one is still around for two
1140           reasons. Some older systems have strange timing problems and seem to
1141           work only with the old driver (which itself does not work with some
1142           newer systems). The other reason is that the old driver is smaller,
1143           since it lacks the enhanced functionality of the new one. This makes
1144           it a good choice for systems with very tight memory restrictions, or
1145           for systems with only older MFM/RLL/ESDI drives. Choosing the old
1146           driver can save 13 KB or so of kernel memory.
1147
1148           If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
1149           instead of this one. For more detailed information, read the
1150           Disk-HOWTO, available from
