Thanks Frank, sorry but I have not enough technical skill to
understand the link. It looks like this is a

Need I load some modules at boot?

I get my board sensors this way:

wget http://khali.linux-fr.org/devel/misc/lm90/Makefile
wget http://khali.linux-fr.org/devel/misc/lm90/i2c-compat.h
wget http://khali.linux-fr.org/devel/misc/lm90/lm90.c
make install
modprobe -r lm90
modprobe lm90

Here is the discussion on the lm-sensor list:

This all data from my board:

# sensors
Adapter: ISA adapter
Core 0:      +27.0°C  (crit = +90.0°C)

Adapter: ISA adapter
Core 1:      +29.0°C  (crit = +90.0°C)

Adapter: SMBus nForce2 adapter at 4d00
temp1:       +50.0°C  (low  = -40.0°C, high = +70.0°C)
                      (crit = +85.0°C, hyst = +75.0°C)
temp2:       +61.6°C  (low  = -40.0°C, high = +70.0°C)
                      (crit = +110.0°C, hyst = +100.0°C)

I want to get maximum number of sensors, I don't know what are the
temp1 and temp2 values.

Is this a good way to get the values?

Thanks again and best regards.
