PI—Ports Implemented Register (D31:F2)
VS—AHCI Version (D31:F2)
Address Offset:
Default Value:
This register indicates which ports are exposed to the ICH6. It is loaded by platform BIOS. It
indicates which ports that the device supports are available for software to use. For ports that are
not available, software must not read or write to registers within that port.
Address Offset:
Default Value:
This register indicates the major and minor version of the AHCI specification. It is BCD encoded.
The upper two bytes represent the major version number, and the lower two bytes represent the
minor version number. Example: Version 3.12 would be represented as 00030102h. The current
version of the specification is 1.0 (00010000h).
