Hello, I have a Gigabyte motherboard, not sure exactly what the code is, but I can find out. I had a quick look at the FAQ and BUGS files, did not find anything that looked directly applicable to my motherboard. I have kernel 2.4.18 and lm-sensors version 2.6.2. Here's the output of sensors and lspci: $ sensors lm80-i2c-0-2d Adapter: SMBus Via Pro adapter at 5000 Algorithm: Non-I2C SMBus adapter +5V: +5.08 V (min = +4.50 V, max = +0.00 V) ALARM VTT: +1.53 V (min = +1.71 V, max = +2.09 V) ALARM +3.3V: +2.59 V (min = +2.97 V, max = +3.63 V) ALARM +Vcore: +1.36 V (min = +2.52 V, max = +3.08 V) ALARM +12V: +12.82 V (min = +10.80 V, max = +13.20 V) ALARM -12V: -11.97 V (min = -13.40 V, max = -11.32 V) -5V: -4.85 V (min = -5.78 V, max = -4.56 V) ALARM fan1: 10546 RPM (min = 6000 RPM, div = 1) fan2: 11637 RPM (min = 6000 RPM, div = 1) temp: -128.00 ?C (hot:limit = +6?C, hysteresis = +5?C) ALARM (os: limit = +6?C, hysteresis = +5?C) ALARM alarms: Board temperature input (a LM75 perhaps?)
