OK, the sensors chip is loacted on the ISA bus. That's what I wanted to

I had a quite long chat today with someone that has the same
motherboard, and it seems that there's a second bus/chipset couple on
this model. You should try to load (in order) i2c-viapro and eeprom, and
you should see a number of eeproms matching the number of memory chips
on the machine. Didn't sensors-detect tell you about this? Or maybe you
just don't care about memory eeproms (and I can't blame you for that

There are many cases where the same chip will require different temp
formulae depending on the motherboard. We do our best to track down all
possible formulae, but we don't own all the hardware existing on the
planet, so there'll always be ones missing. If you can find a formula
that works for you and we are not aware about, please let us know.

You're welcome.
