  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.

 127           the system, leaving the new enhanced IDE driver to take care of only
 128           the 2nd/3rd/4th IDE interfaces.  Doing this will prevent you from
 129           having an IDE/ATAPI CD-ROM or tape drive connected to the primary

 364           Normally, IDE controllers built into the motherboard (on-board
 365           controllers) are assigned to ide0 and ide1 while those on add-in PCI
 366           cards (off-board controllers) are relegated to ide2 and ide3.
 367           Answering Y here will allow you to reverse the situation, with
 368           off-board controllers on ide0/1 and on-board controllers on ide2/3.
 369           This can improve the usability of some boot managers such as lilo
 370           when booting from a drive on an off-board controller.
 371
 372           If you say Y here, and you actually want to reverse the device scan
 373           order as explained above, you also need to issue the kernel command
 374           line option "ide=reverse". (Try "man bootparam" or see the
 375           documentation of your boot loader (lilo or loadlin) about how to
 376           pass options to the kernel at boot time.)
 377
 378           Note that, if you do this, the order of the hd* devices will be
 379           rearranged which may require modification of fstab and other files.

1090           There are two drivers for MFM/RLL/IDE hard disks. Most people use
1091           the newer enhanced driver, but this old one is still around for two
1092           reasons. Some older systems have strange timing problems and seem to
1093           work only with the old driver (which itself does not work with some
1094           newer systems). The other reason is that the old driver is smaller,
1095           since it lacks the enhanced functionality of the new one. This makes
1096           it a good choice for systems with very tight memory restrictions, or
1097           for systems with only older MFM/RLL/ESDI drives. Choosing the old
1098           driver can save 13 KB or so of kernel memory.

1100           If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
1101           instead of this one. For more detailed information, read the
1102           Disk-HOWTO, available from
1103           <http://www.tldp.org/docs.html#howto>.
