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

     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 mappings
     are functional in all models.

     The wmihp driver may conflict with hpqlb(4).
