  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.

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

  70. Do not compile this driver as a module if your root file system (the
  71. one containing the directory /) is located on an IDE device.
  72. If you have one or more IDE drives, say Y or M here. If your system
  73. has no IDE drives, or if memory requirements are really tight, you

  86. a few first-generation SATA controllers.
  87. In order to eliminate conflicts between the two subsystems,
  88. this config option enables the IDE driver's SATA support.

  99. old hard disk driver to control the primary IDE/disk interface in
  100. the system, leaving the new enhanced IDE driver to take care of only

  103. IDE interface. Choosing this option may be useful for older systems
  104. which have MFM/RLL/ESDI controller+drives at the primary port

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

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

  213. pass options to the kernel at boot time) for devices if you want the
  214. native EIDE sub-drivers to skip over the native support, so that
  215. this SCSI emulation can be used instead.
  216. Note that this option does NOT allow you to attach SCSI devices to a

  901. There are two drivers for MFM/RLL/IDE hard disks. Most people use

  903. reasons. Some older systems have strange timing problems and seem to
  904. work only with the old driver (which itself does not work with some
  905. newer systems). The other reason is that the old driver is smaller,
  906. since it lacks the enhanced functionality of the new one. This makes
  907. it a good choice for systems with very tight memory restrictions, or
  908. for systems with only older MFM/RLL/ESDI drives. Choosing the old
  909. driver can save 13 KB or so of kernel memory.

  911. instead of this one. For more detailed information, read the
