109 The driver was largely rewritten for
112 .An Mark Kettenis Aq kettenis@openbsd.org .
113 The driver was then ported to
116 .An Constantine A. Murenin Aq cnst@FreeBSD.org
117 as a part of a Google Summer of Code 2007 project.
119 Some vendors connect these chips to non-standard thermal diodes and
121 This will result in bogus sensor values.
123 Interrupt support is unimplemented.
125 There are currently no known pnpbios IDs assigned to LM chips.
127 This driver attaches to the Winbond W83791SD chip even though that
128 chip does not have any sensors.
