1.9 SATA Interfaces
The board provides four internal SATA connectors through the PCH for internal
storage.
The PCH provides independent SATA ports with a theoretical maximum transfer rate of
3 Gb/s per port. A point-to-point interface is used for host to device connections.
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 Windows* XP, Windows Vista*, and Windows 7* operating
systems.
