+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the
+.Tn National Semiconductor
+LM series hardware monitors and register compatible chips to be used with
+the
+.Xr sysctl 3
+interface.
+.Pp
+Most supported devices possess 11 sensors:
+.Bl -column "Sensor" "Units" "Typical" -offset indent
+.It Sy "Sensor" Ta Sy "Units" Ta Sy "Typical Use"
+.It Li "IN0" Ta "uV DC" Ta "Core voltage"
+.It Li "IN1" Ta "uV DC" Ta "Unknown"
+.It Li "IN2" Ta "uV DC" Ta "+3.3V"
+.It Li "IN3" Ta "uV DC" Ta "+5V"
+.It Li "IN4" Ta "uV DC" Ta "+12V"
+.It Li "IN5" Ta "uV DC" Ta "-12V"

+.It Li "Fan2" Ta "RPM" Ta "Fan"
+.El
+.Pp
+For some devices (most Winbond devices) sensors names and numbers will be
+different.
+.Pp
+Due to hardware limitations, fresh sensor data is only available every
+1.5 seconds.
+.Sh HARDWARE
+Chips supported by the
+.Nm
+driver include:

+.Sh SEE ALSO
+.Xr sysctl 8
+.Sh HISTORY
+The
+.Nm
+driver first appeared in
+.Nx 1.5 ,
+.Ox
+support was added in
+.Ox 3.4 .
+.Sh AUTHORS
+The
+.Nm
+driver was written by
+.An Bill Squier
+and ported to
+.Ox 3.4
+by
+.An Alexander Yurchenko Aq grange@openbsd.org .
+.Sh BUGS
+Interrupt support is unimplemented.
+.Pp
+There are currently no known pnpbios IDs assigned to LM chips.
