          If you say Y here, your kernel will be able to manage low cost mass
          storage units such as ATA/(E)IDE and ATAPI units. The most common
          cases are IDE hard drives and ATAPI CD-ROM drives.

          If your system is pure SCSI and doesn't use these interfaces, you
          can say N here.

          Integrated Disk Electronics (IDE aka ATA-1) is a connecting standard
          for mass storage units such as hard disks. It was designed by
          Western Digital and Compaq Computer in 1984. It was then named
          ST506. Quite a number of disks use the IDE interface.

          AT Attachment (ATA) is the superset of the IDE specifications.
          ST506 was also called ATA-1.

          Fast-IDE is ATA-2 (also named Fast ATA), Enhanced IDE (EIDE) is
          ATA-3. It provides support for larger disks (up to 8.4GB by means of
          the LBA standard), more disks (4 instead of 2) and for other mass
          storage units such as tapes and cdrom. UDMA/33 (aka UltraDMA/33) is
          ATA-4 and provides faster (and more CPU friendly) transfer modes
          than previous PIO (Programmed processor Input/Output) from previous
          ATA/IDE standards by means of fast DMA controllers.

          ATA Packet Interface (ATAPI) is a protocol used by EIDE tape and
          CD-ROM drives, similar in many respects to the SCSI protocol.

          SMART IDE (Self Monitoring, Analysis and Reporting Technology) was
          designed in order to prevent data corruption and disk crash by
          detecting pre hardware failure conditions (heat, access time, and
          the like...). Disks built since June 1995 may follow this standard.
          The kernel itself doesn't manage this; however there are quite a
          number of user programs such as smart that can query the status of
          SMART parameters from disk drives.

          To compile this driver as a module, choose M here: the
          module will be called ide.

          For further information, please read <file:Documentation/ide/ide.txt>.

          If unsure, say Y.

          There are two drivers for Serial ATA controllers.

          The main driver, "libata", uses the SCSI subsystem
          and supports most modern SATA controllers. In order to use it
          you may take a look at "Serial ATA (prod) and Parallel ATA
          (experimental) drivers".

          The IDE driver (which you are currently configuring) supports
          a few first-generation SATA controllers.

          In order to eliminate conflicts between the two subsystems,
          this config option enables the IDE driver's SATA support.
          Normally this is disabled, as it is preferred that libata

          a newer protocol used by IDE CD-ROM and TAPE drives, similar to the
          SCSI protocol. Most new CD-ROM drives use ATAPI, including the
          NEC-260, Mitsumi FX400, Sony 55E, and just about all non-SCSI
          double(2X) or better speed drives.

          If you say Y here, the CD-ROM drive will be identified at boot time
          along with other IDE devices, as "hdb" or "hdc", or something
          similar (check the boot messages with dmesg). If this is your only

          This is the generic IDE driver.  This driver attaches to the
          fixed legacy ports (e.g. on PCs 0x1f0/0x170, 0x1e8/0x168 and
          so on).  Please note that if this driver is built into the
          kernel or loaded before other ATA (IDE or libata) drivers
          and the controller is located at legacy ports, this driver
          may grab those ports and thus can prevent the controller
          specific driver from attaching.

          Also, currently, IDE generic doesn't allow IRQ sharing
          meaning that the IRQs it grabs won't be available to other
          controllers sharing those IRQs which usually makes drivers
          for those controllers fail.  Generally, it's not a good idea

          The CMD-Technologies CMD640 IDE chip is used on many common 486 and
          Pentium motherboards, usually in combination with a "Neptune" or
          "SiS" chipset. Unfortunately, it has a number of rather nasty
          design flaws that can cause severe data corruption under many common
          conditions. Say Y here to include code which tries to automatically
          detect and correct the problems under Linux. This option also
          enables access to the secondary IDE ports in some CMD640 based
          systems.

          This driver will work automatically in PCI based systems (most new
          systems have PCI slots). But if your system uses VESA local bus
          (VLB) instead of PCI, you must also supply a kernel boot parameter
          to enable the CMD640 bugfix/support: "cmd640.probe_vlb". (Try "man
          bootparam" or see the documentation of your boot loader about how to
          pass options to the kernel.)

          The CMD640 chip is also used on add-in cards by Acculogic, and on

          This driver adds up to 4 more EIDE devices sharing a single

          multiple cards can be installed and there are BIOS ROM problems that
          happen if the BIOS revisions of all installed cards (three-max) do
          not match, the driver attempts to do dynamic tuning of the chipset
          at boot-time for max-speed.  Ultra33 BIOS 1.25 or newer is required
