There are two drivers for Serial ATA controllers.
The main driver, "libata", exists inside the SCSI subsystem
and supports most modern SATA controllers.
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 unsure, say N.
