1.5.3 SATA Support
The board provides two SATA interface connectors that support one device per
connector.
The board’s SATA controller offers independent SATA ports with a theoretical
maximum transfer rate of 3.0 Gbits/s on each port. One device can be installed on
each port for a maximum of two SATA devices. A point-to-point interface is used for
host to device connections, unlike PATA which supports a master/slave configuration
and two devices on each channel.
For compatibility, the underlying SATA functionality is transparent to the operating
system. The SATA controller supports IDE and AHCI configuration and can operate in
both legacy and native modes. In legacy mode, standard ATA 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 and Windows Vista* operating systems.
