The underlying SATA functionality is transparent to the operating system.
The SATA
controller can operate in both legacy and native modes.
In legacy mode, standard IDE
I/O and IRQ resources are assigned (IRQ 14 and 15).
In Native mode, standard PCI
Conventional bus resource steering is used.
Native mode is the preferred mode for
configurations using the Microsoft Windows* XP, Windows Vista*, and Windows 7
operating systems.
NOTE
Many SATA drives use new low-voltage power connectors and require adapters or
power supplies equipped with low-voltage power connectors.

SATA RAID
The board supports the following RAID (Redundant Array of Independent Drives) levels
via the PCH:
•
RAID 0
- data striping
•
RAID 1
- data mirroring
•
RAID 0+1 (or RAID 10)
- data striping and mirroring
•
RAID 5
- distributed parity
NOTE
In order to use supported RAID features, you must first enable RAID in the BIOS. Also,
during Microsoft Windows XP installation, you must press F6 to install the RAID drivers.
See your Microsoft Windows XP documentation for more information about installing
drivers during installation. Both Microsoft Windows Vista and Microsoft Windows 7
include the necessary RAID drivers for both AHCI and RAID without the need to install
separate RAID drivers using the F6 switch in the operating system installation process.
