 Hello Rudolf,

 Thanks for your reply!

 As I work on a few free projects on my own, this is a situation I
understand only too well...

 Well, I have hardware and am definitely available to do any (preferably
non destructive :-) tests on it. And I can contribute some of my own time.
Unfortunately not much in the way of money.

 Yes, I was quite impressed by sensors-detect seeing them too. Too bad I
can't see their temperature as then I could try simply running the machine
without the (rear) fan, but I'm too afraid to fry the DIMMs -- they seem to
be quite hot.

 FWIW, I got a reply from Tyan and this is indeed the case.


RM> If you know how to code in C it should not be a problem to write a driver.

 Is there any sufficiently clean and simple driver I could use as an
example/starting point by chance?

 Ah, I started reading the datasheet but didn't reach the most interesting
part, thanks for the page link! I'm going to try it out and report back.

 Thanks,
