1.6.4Serial ATA Interfaces

The board provides four Serial ATA (SATA) connectors, which support one device per connector.

1.6.4.1Serial ATA Support

The DG33BU Desktop Board’s Serial ATA controller offers four independent Serial ATA ports with a theoretical maximum transfer rate of 3 Gbits/sec per port. One device can be installed on each port for a maximum of four Serial ATA devices. A point-to- point interface is used for host to device connections, unlike Parallel ATA IDE which supports a master/slave configuration and two devices per channel.

For compatibility, the underlying Serial ATA functionality is transparent to the operating system. The Serial ATA 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 operating system.
