The system acpi command finds all of the Advanced Configuration and Power Interface (ACPI) tables that are defined by BIOS and displays their associated information. This command can be used to view ACPI signature tables, to dump all table data, and to determine how many logical processors and cores are enabled. Without options, this command displays only defined ACPI tables.
