PI—Ports Implemented Register (D31:F2)
Address Offset: ABAR + 0Ch–0Fh
Default Value:
This register indicates which ports are exposed to the ICH7. 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.
VS—AHCI Version (D31:F2)
Address Offset: ABAR + 10h–13h
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 1.10
(00010100h).
