NAME
       ahci - Advanced Host Controller Interface SATA controller driver

SYNOPSIS
       sata@unit-address

DESCRIPTION
       The ahci driver is a SATA framework-compliant HBA driver that supports SATA HBA controllers that are compatible with the Advanced Host Con-
       troller Interface 1.0 specification. AHCI is an Intel-developed protocol that describes the register-level interface for  host  controllers
       for  serial  ATA  1.0a  and Serial ATA II. The AHCI 1.0 specification describes the interface between the system software and the host con-
       troller hardware.

       The ahci driver currently supports the Intel ICH6/7/8/9, VIA vt8251 and JMicron AHCI controllers which are compliant with the Advanced Host
       Controller  Interface  1.0  specification.  Note that while the	Intel ICH6/7/8/9, VIA vt8251 and JMicron AHCI controllers support standard
       SATA features, the ahci driver currently only supports hard disk, ATAPI SATA DVD, hotplug and NCQ (Native command queuing). Port multiplier
       and power management  are not yet supported.

CONFIGURATION
       The ahci module contains no user configurable parameters.
