HISTORY
The acpiwmi device driver appeared in NetBSD 6.0.
AUTHORS
Jukka Ruohonen <jruohonen@iki.fi> wrote the actual acpiwmi as well as wmidell and wmihp. The wmihp was based on the earlier work done by Michael Gmelin <freebsd@grem.de> for FreeBSD.
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 conflicts with hpqlb(4).
