<h2>Description</h2>
<p>The acpi driver provides support for the Intel/Microsoft/Compaq/Toshiba
ACPI standard. This support includes platform hardware discovery (super-
seding the PnP and PCI BIOS), as well as power management (superseding
APM) and other features. ACPI core support is provided by the ACPI CA
ACPI standard. This support includes platform hardware discovery (superseding
