T
he controller contains two modes of operation—a
legacy mode using I/O space, and an AHCI mode
using memory space. Software that uses legacy
mode will not have AHCI capabilities.
The AHCI ( Advanced Host Controller Interface) is a
programming interface which defines transactions
between the SATA controller and software and
enables advanced performance and usability with
SATA. Platforms supporting AHCI may take advantage
of performance features such as no master/slave
designation for SATA devices—each device is treated
as a master—and hardware assisted native command
queuing. AHCI also provides usability enhancements
such as Hot-Plug. Here is the list of the AHCI capabilities
which exist in the system:
Hardware assisted native command queuing
1.
Aggressive power management
2.
LED indicator support
3.
Note:
To configure your hard disk as AHCI
compatible, use the BIOS menu. Refer to
IDE
Configuration Settings
on

.
Also, Intel(R) Matrix Storage Manager (for use on
systems using Intel(R) 82801HBM I/O Controller
Hub (ICH8M)- AHCI only) has to be installed, for
