16.3.2 acpi

Command: acpi [-1|-2] [--exclude=table1,…|--load-only=table1,…] [--oemid=id] [--oemtable=table] [--oemtablerev=rev] [--oemtablecreator=creator] [--oemtablecreatorrev=rev] [--no-ebda] filename …

Modern BIOS systems normally implement the Advanced Configuration and Power Interface (ACPI), and define various tables that describe the interface between an ACPI-compliant operating system and the firmware. In some cases, the tables provided by default only work well with certain operating systems, and it may be necessary to replace some of them.

Normally, this command will replace the Root System Description Pointer (RSDP) in the Extended BIOS Data Area to point to the new tables. If the --no-ebda option is used, the new tables will be known only to GRUB, but may be used by GRUB’s EFI emulation.
