[lm-sensors] lm-sensors in AMOS 3000 Via embedded computer

[antonio.exposito]

I have an AMOS 3000 embedded PC, based on a EPIA P700 board. I am 
testing a unit with AMOS 3000 - EPIA P700 - C7 1 Ghz, to know how much 
can I get from it. 

I installed Ubuntu 9.04, kernel 2.6.28 (also 2.6.31) successfully but 
I found some issues. The PC gets really hot at full load and it halted 
by overtemperature during the installation of additional software. This 
motherboard, EPIA P700 has a C7 processor with fanless heat sink, VX700 
chipset, ADM1032 and SUPER I/O VT1212 Lite, but lm-sensors 3.1.1 doesn’
t detect any sensor, only c7temp driver is demanded. I patched my 
kernel and I tried to compile the c7temp module but it gives a 
meaningless reading, 1 Volt 0 Celsius (I dislike this driver, so I 
prefer to get working ADM1032 one). I don’t know if it supports 
hardware monitoring. I only am able to find two devices in the SMBUS 
(SDRAM and clock) without any clues about where is the ADM1032 chip. 

This board is based on a VX700 chipset, and a VT1212 Super I/O chip, 
and I have read in the P700 datasheet and operating manual that it is 
in charge of hardware monitoring in this board.

Which is the best way to get lm-sensors woking in this motherboard, 
ADM1032 or VT1212?  Anyone has any clue?

I think that these devices are hidden (BIOS manufacturer 
configuration), anybody knows how to unhide the SMBUS devices?

Thank you in advance and regards,

Antonio

You can try the via-cputemp driver:

VT1212 does not contain any hardware monitoring capabilities. It must
be the ADM1032 then.

Don't know how to do that for a VX700 chip.
