The SATA host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as the Shadow Register Block. All SATA devices behave like Device 0 devices. For additional information about how SATA emulates parallel ATA, refer to the “Serial ATA International Organization: Serial ATA Revision 3.0”. The specification can be downloaded from www.sata-io.org.

The host adapter may, optionally, emulate a master/slave environment to host software where two devices on

separate SATA ports are represented to host software as a Device 0 (master) and Device 1 (slave) accessed at Note the same set of host bus addresses. A host adapter that emulates a master/slave environment manages two

sets of shadow registers. This is not a typical SATA environment.
