  51           There are two drivers for Serial ATA controllers.
  52
  53           The main driver, "libata", uses the SCSI subsystem
  54           and supports most modern SATA controllers. In order to use it
  55           you may take a look at "Serial ATA (prod) and Parallel ATA
  56           (experimental) drivers".
  57
  58           The IDE driver (which you are currently configuring) supports
  59           a few first-generation SATA controllers.
  60
  61           In order to eliminate conflicts between the two subsystems,
  62           this config option enables the IDE driver's SATA support.
  63           Normally this is disabled, as it is preferred that libata
  64           supports SATA controllers, and this (IDE) driver supports
  65           PATA controllers.

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

 240
 241           This driver will work automatically in PCI based systems (most new
 242           systems have PCI slots). But if your system uses VESA local bus
