This utility will read the ACPI tables, if any, that were presented to the kernel from the BIOS at boot and display the information. The tables will be printed out in hexidecimal format and can be parsed with the acpixtract(1) and madt(1) utilities.
The following options are supported:
-a [address]
Allows the user to specify the starting address from which to dump the tables.
-b
Dump the ACPI tables in binary mode.
-h
Display the help menu containing the options supported by the utility.
-l [length]
Requires a starting address, specified with -a, and will dump the range of physical address but makes no attempt to understand the contents of that memory.
-o [file]
Redirect the output provided by the utility to the specified file.
-s [count]
Skip count tables of the given name
-t [table]
Dump only the table with the table signature.
