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.
