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

  60           The IDE driver (which you are currently configuring) supports

 207           This is the generic IDE driver.  This driver attaches to the
 208           fixed legacy ports (e.g. on PCs 0x1f0/0x170, 0x1e8/0x168 and
 209           so on).  Please note that if this driver is built into the
 210           kernel or loaded before other ATA (IDE or libata) drivers
 211           and the controller is located at legacy ports, this driver
 212           may grab those ports and thus can prevent the controller
 213           specific driver from attaching.
 214
 215           Also, currently, IDE generic doesn't allow IRQ sharing
 216           meaning that the IRQs it grabs won't be available to other
 217           controllers sharing those IRQs which usually makes drivers
 218           for those controllers fail.  Generally, it's not a good idea

 760           normally be on; disable it only if you are running a custom hard
 761           drive subsystem through an expansion card.

 780         help
 781           Certain older chipsets, including the Tekram 690CD, use a single set
 782           of I/O ports at 0x1f0 to control up to four drives, instead of the
 783           customary two drives per port. Support for this can be enabled at
 784           runtime using the "ide-4drives.probe" kernel boot parameter if you
 785           say Y here.
