Fortunately, it happens that my ADSL modem/router uses a 15V/1A PSU, which I can borrow for my tests. The only drawback is that I have to choose between Internet access and the ADM1025 evaluation board ;) > > 3* What does it take to a chip to be "ACPI-compliant"?

I am sorry to say that you did not really answered my question ;) My concerns here are technical. I know what a standard is, I understand that parts can comply or not with it. What I am curious about are the technical characteristics a temperature monitoring chip has to meet to comply with the ACPI standards. Now, I have been playing with the ADM1025 eval board and I have the bad feeling that it doesn't work as it should. Temperatures are OK, +2.5V, VCore, VCC and vid are correct, but +3.3V, +5V and +12V (when selected) are not. Their values are changing randomly all the time. I tried on my other computer with the Windows evaluation software, and that's the same story, so it's not a matter of system or Linux driver. Any idea on what's going on or how I can fix that? Another strange behavior I noticed as I was trying to understand and workaround the first problem, in case it helps: if I select +12V on the board but VID4 inside the chip, all measurements go wrong, including temperatures. I'd have expected +12V and/or vid to be wrong, of course, but why is this breaking everything else too? Thanks. -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
