Hello As avised by Jean Delvare i define again my pb 1. DEF Under Mandrake 9.2 kernel 2.4.22.10 lm*sensors 2.8.0 i have : asb100/CPU Temp, asb100/M/B Temp and asw83l785ts/NeForce2 Temp we see the three temperatures which change during second, minute Under Mandriva LE 2005 kernel 2.6.11 lm-sensors 2.9.0 and Mandriva 2006 RC1 kernel 2.6.12 lm-sensors 2.9.1 i have : asb100/CPU Temp, asb100/M/B Temp and asw83l785ts/NeForce2 Temp we see temperatures which change during second, minute for M/B and NeForce2 but the temperature of CPU Temp stays steady during all day, week, month. my bios gives me the MB temp and the CPU temp. Under MDK 9.2 i very that : - asb100/MB temp is the bios/MB temp - asb/100/CPU temp is the bios CPU temp Under MDV LE 2005 and 2006rc1 i verify that : - asb100/MB temp is the bios/MB temp - asb/100/CPU temp(48 ?C <=> 25*1.9) is a type of CPU temp but stays steady in the contrary of the bios CPU temp which changes frequently. 2.
