Hi! I reported a bug of asb100 chip at: http://www2.lm-sensors.nu/~lm78/readticket.cgi?ticket=1539 The reply was the follow: "Is there a BIOS option you can disable, e.g. Asus "COP", "QFAN", or some such? My guess is that the BIOS is somehow interfering with the asb100 driver. Otherwise I don?t know how this could happen. You could followup with a message to the mailing list: <sensors at Stimpy.netroedge.com> (no need to subscribe) Let us know what board you have, and if the above suggestion solves the problem. MMH 2004-01-26" The answers: mobo: ASUS A7V333-X (BIOS rev. 1004) There is a "Q-Fan Control" option in BIOS, but is disabled. The "COP" is a property of the mobo, but i can't turn it off in BIOS. So the above suggestion doesn't solve the problem. Misi
