Syntax

acpiview [-s table signature | -a] [-p] [-d] [-v] [-b] [-n] ID [-o] name [-t] name

Description

Displays and disassembles Advanced Configuration and Power Interface (ACPI) tables.

Options

-s table signature: Displays the specified ACPI table. Except for the RSDP descriptor, the table signature must be a defined value in the ACPI spec. Use RSDP instead of RSD PTR.
-a: Decodes and displays all ACPI static tables.
-p: Decodes and displays all ACPI static tables, and disassembles the AML code in the descriptor tables.
-d: Dumps ACPI table hexadecimal data while decoding tables.
-v: Displays ACPI table verbose data while decoding tables.
-n ID: Displays the descriptor table specified by an OEM table ID.
-b: Displays one screen at a time.
-o name
-t name: Dumps the binary ACPI data for descriptor tables to the file named.

Usage

Include one of the -s, -a, or -p parameters.

The -p option, with no other options specified, dumps, and then parses all ACPI tables.

If -v, -d, or -o are not specified, verbose mode is automatically enabled.

The -n option requires a full 8-character OEM table ID string. To include spaces, use quotation marks (" ").

The -o option requires a writable file system.

Examples

fs0:\> acpiview -p

To dump and parse only the DSDT:

fs0:\> acpiview -p -s DSDT

To dump and parse the SSDT table with OEM table ID PCISSDT:

fs0:\> acpiview -p -s SSDT -n PCISSDT

To dump all ACPI tables with no parsing of AML:

fs0:\> acpiview -a
