+          This option enables limited support for the Marvell 88SE61xx ATA
+          controllers. If you wish to use only the SATA ports then select
+          the AHCI driver alone. If you wish to the use the PATA port or
+          both SATA and PATA include this driver.
 
           If unsure, say N.
