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

  57. "master" and a "slave" device, for a total of up to twenty ATA/IDE
  58. disk/cdrom/tape/floppy drives.
  59. Useful information about large (>540 MB) IDE disks, multiple
  60. interfaces, what to do if ATA/IDE devices are not automatically
  61. detected, sound card ATA/IDE ports, module support, and other
  62. topics, is contained in <file:Documentation/ide.txt>. For detailed
  63. information about hard drives, consult the Disk-HOWTO and the
  64. Multi-Disk-HOWTO, available from
  65. <http://www.tldp.org/docs.html#howto>.
  66. To fine-tune ATA/IDE drive/interface parameters for improved
  67. performance, look for the hdparm package at

  72. one containing the directory /) is located on an IDE device.
  73. If you have one or more IDE drives, say Y or M here. If your system
  74. has no IDE drives, or if memory requirements are really tight, you

  83. There are two drivers for Serial ATA controllers.
  84. The main driver, "libata", uses the SCSI subsystem
  85. and supports most modern SATA controllers. In order to use it
  86. you may take a look at "Serial ATA (prod) and Parallel ATA
  87. (experimental) drivers".
  88. The IDE driver (which you are currently configuring) supports
  89. a few first-generation SATA controllers.
  90. In order to eliminate conflicts between the two subsystems,
  91. this config option enables the IDE driver's SATA support.
  92. Normally this is disabled, as it is preferred that libata

  107. which have MFM/RLL/ESDI controller+drives at the primary port

  127. This setting is irrelevant for most IDE disks, with direct memory
  128. access, to which multiple sector mode does not apply. Multiple sector
  129. mode is a feature of most modern IDE hard drives, permitting the
  130. transfer of multiple sectors per Programmed Input/Output interrupt,
  131. rather than the usual one sector per interrupt. When this feature is
  132. enabled, it can reduce operating system overhead for disk Programmed
  133. Input/Output. On some systems, it also can increase the data
  134. throughput of Programmed Input/Output. Some drives, however, seemed
  135. to run slower with multiple sector mode enabled. Some drives claimed
  136. to support multiple sector mode, but lost data at some settings.
  137. Under rare circumstances, such failures could result in massive
  138. filesystem corruption.

  223. This will provide SCSI host adapter emulation for IDE ATAPI devices,

  226. This is useful if you have an ATAPI device for which no native
  227. driver has been written (for example, an ATAPI PD-CD drive);
  228. you can then use this emulation together with an appropriate SCSI
  229. device driver. In order to do this, say Y here and to "SCSI support"

  931. There are two drivers for MFM/RLL/IDE hard disks. Most people use
  932. the newer enhanced driver, but this old one is still around for two
  933. reasons. Some older systems have strange timing problems and seem to
  934. work only with the old driver (which itself does not work with some
  935. newer systems). The other reason is that the old driver is smaller,
  936. since it lacks the enhanced functionality of the new one. This makes
  937. it a good choice for systems with very tight memory restrictions, or
  938. for systems with only older MFM/RLL/ESDI drives. Choosing the old
  939. driver can save 13 KB or so of kernel memory.
  940. If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
  941. instead of this one. For more detailed information, read the
