Advanced Configuration and Power Interface (ACPI) Tables

BIOSes with ACPI support provide numerous tables of data describing a computer's configuration and power management capabilities. The functions given in this section can be used to retrieve these tables. Declarations of these functions and table structures are available in file Include\Rttacpi.h and Libdel\Rttacpi.pas.

The ACPI structure declarations included in the following sections and in file Include\Rttacpi.h correspond to version 3.0 of the ACPI specification. Older ACPI versions may only support a subset of the declared structure fields as later ACPI versions have appended data members to some structures. Function RTACPIIsValid may be used to check if a particular structure member is supported.

More detailed information about the contents of the ACPI tables is available in the Advanced Configuration and Power Interface Specification revision 3.0a, downloadable from http://www.acpi.info/spec.htm.
