865PE hardware sensors

865PE hardware sensors

Post by Jonathan Rawl » Tue, 02 Mar 2004 05:02:46



I have an AOpen AX4SPE-UN motherboard that uses the Intel 865PE chipset, and
I'd like to get the onboard sensors working.

I have run sensors-detect and it appears to recongise the sensors and access
them through the ISA bus. When I type "sensors" I now see information for a
whole load of sensors, but the values appear to be nonsense:

it87-isa-0290
Adapter: ISA adapter
Algorithm: ISA algorithm
VCore 1:   +2.68 V  (min =  +1.42 V, max =  +1.56 V)   ALARM
VCore 2:   +3.13 V  (min =  +2.40 V, max =  +2.60 V)
+3.3V:     +6.56 V  (min =  +3.12 V, max =  +3.44 V)
+5V:       +5.04 V  (min =  +4.72 V, max =  +5.24 V)
+12V:      +6.12 V  (min = +11.36 V, max = +12.60 V)
-12V:     -27.36 V  (min = -12.63 V, max = -11.41 V)
-5V:      -13.64 V  (min =  -5.28 V, max =  -4.81 V)
Stdby:     +0.94 V  (min =  +0.00 V, max =  +0.00 V)
VBat:      +4.08 V
fan1:     11250 RPM  (min =    0 RPM, div = 2)          ALARM
fan2:     1350000 RPM  (min = 5314 RPM, div = 1)          ALARM
fan3:     675000 RPM  (min = 3000 RPM, div = 2)          ALARM
M/B Temp:    -12C  (low =   +0C, high =  +40C)         ALARM
CPU Temp:     -1C  (low =  +25C, high =   +0C)         ALARM
Temp3:       -16C  (low =  +25C, high =  +45C)         ALARM

I only have one fan, the CPU fan, and that runs very slowly. So I don't
expect it to be detected correctly. But all of the other sensors give
sensible values in the BIOS screen.

I use Fedora Core 1.

Does anyone now know to configure it to return correctly-calibreted values?

Many thanks,

Jonathan Rawle

The it87 module takes a parameter (temp_type) that specifies which
device(thermistor or diode) is enabled for each temperature sensor. I would
suggest that you read the /etc/sensors.conf file and the docs for the it87
chip included with lm_sensors. If I remember correctly there were 6
different values for temp_type that could be used.

1. Dell hardware sensors.

I was curious if there were any Dell server hardware sensor patches, for
things such as power supply failures, fan outages, etc. Specifically
anything available for the 6650 and such newer type series servers.

TIA.
