Thanks for the information everyone, it's installed (from the DVD) and
up and running, now I have to figure out how to compute the proper
temperatures.
Temps are reported from the w83627thf chip & sensors as:
M/B: -3
CPU1 -3.0
CPU2 -3.0
I've tried putting in equations for the calculation of the temps to
resemble the BIOS temps but the equations seem to be ignored:
-- snip --
# ThermistorType = ???
# Fix up a 'compute' line to match your thermistor type.
# Warning. You still don't have enough information to do this.
# ThermistorType = N
compute temp1 ((4.71 * @) * -1)
# ThermistorType = (??)
compute temp2 ((4.71 * @) * -1)
# ThermistorType =
compute temp3 ((4.71 * @) * -1)
# ThermistorType =
# compute temp ((X * ((1.20 * @) - 62.77)) - Y), ...
# set limits to 5% for the critical voltages
<< DELETED >>
# set up sensor types (thermistor is default)
# 1 = PII/Celeron Diode; 2 = 3904 transistor;
# 3435 = thermistor with Beta = 3435
# If temperature changes very little, try 1 or 2.
# set sensor1 1
# set sensor2 2
# set sensor3 3435
label temp1 "M/B Temp"
label temp2 "CPU1 Temp"
label temp3 "CPU2 Temp"
# ignore temp3
-- snip --
The information above is just a quick and dirty calculation, not a
detailed numerical analysis to produce the proper equation, though if
someone already has done this I would appreciate it very much if you
could pass on your knowledge.
The instructions in sensors.conf & the LM_sensors haven't really helped
me much so if someone could provide some help I'd be grateful.
