  Hi.

I am using lm_sensors in a slightly patched form.
The motherboard is Intel D845BGL, which features
SMSC LPC47M142 LPC Bus I/O controller.

If you look at the 47m10x and 47m14x datasheets,
you'll notice they have different Device ID's
(the former has 0x59, the latter 0x5F). As far
as the fan monitoring is concerned, they are
pretty much identical.

The 47M142 will be recognized with only some
trivial modifications to the code. I've attached
diffs for lm_sensors-2.7.0 and lm_sensors-2.8.0.


Best regards,

Kalev Soikonen
