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 Controller  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 I. 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 JMi-
     cron AHCI controllers support standard  SATA  features,  the
     ahci  driver  currently  only supports hard disk, ATAPI SATA
     DVD, hotplug and NCQ (Native command queuing).  Port  multi-
     plier and power management  are not yet supported.

CONFIGURATION
     The ahci module contains no user configurable parameters.

NOTES
     To bind the ahci  driver  to  your  controller,  choose  the
     [AHCI] BIOS option.


     Note that booting is not supported if toggle exists  between
     the [IDE] and [AHCI] BIOS options
