|
|
Hi,
I've emerged lmsensors, configured it with sensors-detect, and loaded all the kernel modules with the lm_sensors script in /etc/init.d.
I've got six temperture readings, 3 for something called via686-isa-e200 and 3 others for something called as99127f-i2c-0-2d. Now, I have no idea what these things are, though I can find them in /proc. I'm mostly interested in monitoring my cpu temps, but none of the temperture readings come close to what my bios says they are. On a reboot my bios typically reports that my cpu temp is around 57 degrees centigrade. lm_sensors reports nothing even close to that.
I guess I've really got two questions: Can the kt133 chipset report a cpu temperture to lm_sensors and, if so, how do I determine which sensor is for my cpu?
Thanks,
Seth |

I've had a similar problem with lm_sensors detecting several sensor chips I don't really have (via kt133 board). This way I got lots of bogus Sensor values (about 20), but in the BIOS I had only 9 (CPU temp., SYS temp., CPU fan, SYS fan, V_core, V_dd, +3.3V, +5V, +12V)
After some googling and trial & error I found the following configuration working:
loaded modules:
i2c-core
i2c-dev
i2c-proc
i2c-isa
via686a
possibly you also have to tweak your /etc/sensors.conf (the"via686a-*" section) to get the labels right (I had SYS and CPU temp. swapped).
One more thing: Avoid running sensors as root! I read somwhere that this could cause sensors to set the ALARM settings to incorrect values, so that the PC would not boot anymore because the initial CPU temp. was always above the alarm value. When run as user, senors cannot set Alarm settings. |

Thanks for the tips. I'll take a look at my sensors.conf.

KT133 is the Northbridge of your chipset.
Sensors function via the Southbridge, probably a VIA 686a or b.
For my 686b, I need;
modprobe i2c-viapro
modprobe i2c-isa
modprobe via686a
for correct readings (correct means: identical to the ones I read from the BIOS).
mr_neutron probably has the right setting for a via686a southbridge. |

Thanks, but you lost me at the Northbridge/Southbridge business. Should I just load the i2c-viapro, i2c-isa, and via686a modules? And if via686a doesn't do the trick should I try via686b?
Thanks again,
Seth |

KT133 is just one chip from a chipSET.
The command "sensors-detect" will probably tell you which modules you need for your motherbooard, and my guess is it's either mr_neutron's config, or mine. |
