That may be because the script/program responsible does not run, ie, exits, if it doesn't find the configuration file.
I feel that we are starting to lose the plot here.
I posted my original message for the simple reason that by having the lm_sensors file created a high-pitched noise started up when I booted into SUSE. It took a while to locate the reason for this noise so I posted the message in case someone else, at some future time, strikes the same problem and wonders what may be the sudden cause of the noise.
Joe Morris responded with the statement that nothing happens with lm_sensors until one copies the startup script from /usr/share/doc/packages/sensors/prog/init to /etc/init.d and then enables the script; he asked if I did this and I answered NO.
By accepting that this script had to be activated before lm_sensors started to actually work, I suggested that my (original) message was more relevant than I initially thought because here was a control file causing noise when the script which used it wasn't even activated (and that when this file was removed the noise stopped).
While I still don't really know how lm_sensors work or what makes it work, after reading quickly the wording of the lm_sensors file created by /usr/sbin/sensors-detect command I now think that in SUSE 10.1 the sensors start working when the file lm_sensors exists in /etc/sysconfig - and this goes contrary to what Joe suggested.
If this is the case, that the sensors app. runs when lm_sensors is present in /etc/sysconfig, then it makes perfect sense why the noise stops when I rename the lm_sensors file - and what you state above is correct.
But we got to this point after tossing some ideas around :-) . However, I hope that my original posting, about what may be causing the sudden appearance of a high-pitched noise when fooling around with lm_sensors, comes in handy to someone in the future. The only thing we haven't resolved - but does it matter? - is what exactly in the parameters created by sensors-detect is causing the noise to be generated? :-)
Cheers.
I very happy to see Basil refocus this discussion on his original issue. For one, I am quite interested in learning something of value from this discussion and I am having trouble wading through all the words for the meat. Sorry! My understand of lm_sensors (which could easily be very wrong) is that it reads out from various registers on the MBO values and then displays them for us. I was always under the impression that it is read only. How can a read only program cause a change that sets off Basil's alarm? Someone smart please explain that? In addition, Steve Boddy in a post to this thread said: This may sound like an silly question, but is it possible it's an alarm? I've always found the lm_sensors stuff a bit hit and miss for detecting and setting things properly, like putting odd values in for alarm conditions. Not understanding the detail of how it works, it may be seeing something it doesn't like and generating an audible alarm. w83697hf-isa-0290 Adapter: ISA adapter VCore: +1.66 V (min = +1.71 V, max = +1.89 V) ALARM +3.3V: +1.49 V (min = +3.14 V, max = +3.47 V) ALARM +5V: +4.87 V (min = +4.76 V, max = +5.24 V) +12V: +12.04 V (min = +10.82 V, max = +13.19 V) -12V: +1.54 V (min = -13.18 V, max = -10.80 V) ALARM -5V: +0.13 V (min = -5.25 V, max = -4.75 V) ALARM V5SB: +5.46 V (min = +4.76 V, max = +5.24 V) ALARM VBat: +3.15 V (min = +2.40 V, max = +3.60 V) fan1: 2766 RPM (min = 84375 RPM, div = 8) ALARM fan2: 0 RPM (min = 1739 RPM, div = 8) ALARM temp1: +38 C (high = +34 C, hyst = -92 C) sensor = thermistor ALARM temp2: +46.5 C (high = +100 C, hyst = +95 C) sensor = thermistor alarms: beep_enable: Sound alarm enabled As you can see, after a quick detect and init, I've got crazy values in some fields, and alarms up the kazoo. Note also the beep_enable at the end. I guess if that was wired up properly I'd be being annoyed right now by a high pitched noise ;-) I also have these alarms from the voltages being out of range from the norm. However, it is clear to me, (maybe I am stupid) that these voltages can't be incorrect as the BIOS looks fine and the machine works perfectly. Have any of you found what the right method to edit these files for accuracy? I suppose i could get the MBO manuals out and try to find the proper numbers from the manufacture. Seems a bit arcane though. Again, my goal would be to learn and document more about the use of lm_sensors from as many smart people as I can for current and future reference. Hopefully no one reacts negatively to this, I just want to get smarter if possible. And yes, I have done a lot reading and note taking from the man pages and other DOC. Cheers, Bob
