a task file containing ata commands that are sent back to the drive to restore
it to boot up defaults.

+ This option adds support for SATA-related ACPI objects.
+ These ACPI objects add the ability to retrieve taskfiles
+ from the ACPI BIOS and write them to the disk controller.
+ These objects may be related to performance, security,
+ power management, or other areas.
+ You can disable this at kernel boot time by using the
+ option libata.noacpi=1
