# 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).
