A few ones does.
I had once in my power 2 revisions, that had differents sensors config.
(However, this were old mb)

I was also looking into this.
Even most bioses says the mainboard version/revision at the bottom of
the screen usually (i.e. award)

i think, using a combinatory of dmidecode for individual detection of
sensors/mainboard, and using some other tools/complements.

I'll work on some of the ideas, to see which ones are more effective.
Although, i dont think the first implementation has got to be the
deffinite one. This month i want to have a basic but working system, and
the next one, improve it a lot.
I dont pretend to dish the project after SoC either, so as we can get
more info to detect mainboards, better.

I'll take a look onto this DOS tools. Or perhaps disasm some of these
"flash" utilities could help to get where to read......
Well, thanks a lot for the welcomes, and ideas :)

The most, the more thanks.
