lm_sensors and wrong values on MSI MS-6704 (845PE Max2 FIR)

Dear Sirs,

I am trying to install support for monitoring cpu temp under
my redhat 9.0 box, but without much success.
I have ran sensors-detect, which identified LM80 in my
system. Everything seems to have been installed fine,
but the readings I get are:

lm80-i2c-0-2f
Adapter: SMBus I801 adapter at 0c00
Algorithm: Non-I2C SMBus adapter
+5V:       +6.71 V  (min =  +6.71 V, max =  +6.71 V)   ALARM
VTT:       +2.55 V  (min =  +2.55 V, max =  +2.55 V)   ALARM
+3.3V:     +4.43 V  (min =  +4.43 V, max =  +4.43 V)   ALARM
+Vcore:    +3.76 V  (min =  +3.76 V, max =  +3.76 V)   ALARM
+12V:     +16.10 V  (min = +16.10 V, max = +16.10 V)   ALARM
-12V:     -16.11 V  (min = -16.11 V, max = -16.11 V)   ALARM
-5V:       -6.70 V  (min =  -6.70 V, max =  -6.70 V)   ALARM
fan1:        0 RPM  (min =    0 RPM, div = 8)          ALARM
fan2:        0 RPM  (min =    0 RPM, div = 8)          ALARM
temp:     -1.00 C (hot:limit =  -1C,  hysteresis =  -1C) ALARM
         (os: limit =  -1C,  hysteresis =  -1C) ALARM
alarms:   Board temperature input (LM75)               ALARM

eeprom-i2c-0-50
Adapter: SMBus I801 adapter at 0c00
Algorithm: Non-I2C SMBus adapter
Memory type:            DDR SDRAM DIMM SPD
SDRAM Size (MB):        512

eeprom-i2c-0-51
Adapter: SMBus I801 adapter at 0c00
Algorithm: Non-I2C SMBus adapter
Memory type:            DDR SDRAM DIMM SPD
SDRAM Size (MB):        512

These values are constant (I have never seen them change) and of course
are not in accordance with what I see from my boards
monitor. By the way, the manifacturer supplied monitor
supports 2 temps (CPU & system), 3 Fan speeds & voltages.
Is there a way I can check if sensor_detect has
made the right decision?
Can somebody help me to get the correct values in my system?

(I am sending this e-mail because there was such a statement in
sensors.conf, regarding the LM80 chip...)

George
