Hi, Best would be to ask the for additional docs but lets check what we can find out on our own: > Results: > 0 1 2 3 4 5 6 7 8 9 a b c d e f > 00: ff 03 00 00 ff ff ff ff ff ff ff ff ff ff ff ff > 10: 00 00 00 00 ff ff ff ff ff ff ff ff ff ff ff ff > 20: d3 af ab 83 7a 8a 76 d6 c3 ff ff ff ff ff ff ff > 30: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > 40: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > 50: ff ff ff ff ff ff ff ff ff ff 03 04 10 19 34 ff > 60: 00 00 00 00 ff ff 02 74 00 00 ff 06 40 24 ff 00 > 70: ff ff 2e ff 1f ff 00 ff ff ff ff ff ff ff ff ff > 80: ff ff 65 64 64 55 55 46 ff ff ff ff ff ff a8 ff > 90: 00 0c 0c 00 15 ff 57 ff 44 22 ff aa 55 55 ff 0a > a0: 01 d1 00 ff 02 23 3c 32 28 1e ff d9 b2 99 80 01 > b0: 02 1b 00 99 02 1b 3c 32 28 1e ff d9 b2 99 80 02 > c0: 0f ff 00 80 03 ff 3c 32 28 1e ff d9 b2 99 80 03 > d0: 0f ff 00 80 03 ff 3c 32 28 1e ff d9 b2 99 80 03 Perhaps the chip can control the fans too. and set some limits... this would be the undocumented a2-af fields > e0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > f0: 00 00 00 00 00 00 37 ff 02 ff ff 02 ff ff ff ff > > The results seem to be correct systemp is around the 30C as shown in the > results from isadump and checked with the bios. > I do have my doubts about the cpu temp reported in the isadump it says it's > around 45C but when checking in the bios it shows almost 60C.

If you manage to see something like this then proceed down to check what logical device the chip resides. Just switch do dumps with > ruik:/tmp# isadump -k 0x87,0x87 0x2e 0x2f 2 and change the last number from 0 1? to 15 and check the bytes at 60: you should see the 02 90 or 02 95 > question 5) answer: isadump -f 0x290 Please provide this dump too Thanks, Rudolf
