	  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
	  supports SATA controllers, and this (IDE) driver supports
	  PATA controllers.

	  If you have a CD-ROM drive using the ATAPI protocol, say Y. ATAPI is
	  a newer protocol used by IDE CD-ROM and TAPE drives, similar to 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

	  CD-ROM drive, you can say N to all other CD-ROM options, but be sure

	  If you have an IDE tape drive using the ATAPI protocol, say Y.
	  ATAPI is a newer protocol used by IDE tape and CD-ROM drives,
	  similar to the SCSI protocol.  If you have an SCSI tape drive
	  however, you can say N here.

	  You should also say Y if you have an OnStream DI-30 tape drive; this
	  will not work with the SCSI protocol, until there is support for the
	  SC-30 and SC-50 versions.

	  If you say Y here, the tape drive will be identified at boot time
	  along with other IDE devices, as "hdb" or "hdc", or something
	  similar, and will be mapped to a character device such as "ht0"
	  (check the boot messages with dmesg).  Be sure to consult the

	  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
	  to load IDE generic driver on modern systems.

	  If unsure, say N.

	help
	  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
	  the "CSA-6400E PCI to IDE controller" that some people have. For

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

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

	  This can improve the usability of some boot managers such as lilo
	  when booting from a drive on an off-board controller.

	  Note that, if you do this, the order of the hd* devices will be
	  rearranged which may require modification of fstab and other files.
