DESCRIPTION

     The acpiwmi device driver provides an ACPI interface for Windows Management Instrumentation (WMI).  The ACPI WMI interface is typically used
     to support vendor specific features found in various laptops.

     The following WMI mappings are supported:

	   wmidell   Dell laptops

	   wmieeepc  Some models of Asus Eee PC

	   wmihp     Hewlett-Packard laptops

	   wmimsi    MSI laptops

     The functionality varies from vendor to vendor.  Typically the interface is used for function and hotkey handling, but additional features
     may be present.

HISTORY

     The acpiwmi device driver appeared in NetBSD 6.0.

AUTHORS

     Jukka Ruohonen <jruohonen@iki.fi> wrote acpiwmi and most of the mappings.

CAVEATS

     While WMI should provide a certain degree of portability across laptop models from a particular vendor, there is no guarantee that the map-
     pings are functional in all models.

     The wmihp driver may conflict with hpqlb(4).
