 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

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

803           Certain older chipsets, including the Tekram 690CD, use a single set
804           of I/O ports at 0x1f0 to control up to four drives, instead of the
805           customary two drives per port. Support for this can be enabled at
