+          compliant or similar programming interface.
+
+          SFF is the legacy IDE interface that has been around since
+          the dawn of time.  Almost all PATA controllers have an
+          SFF interface.  Many SATA controllers have an SFF interface
+          when configured into a legacy compatibility mode.
+
+          For users with exclusively modern controllers like AHCI,
+          Silicon Image 3124, or Marvell 6440, you may choose to
+          disable this uneeded SFF support.
