No sensors found!

I am a complete newbie here cutting my teeth on RedHat 9 Kernel
2.4.20-8smp. I am trying to get lm_sensors to work but I continually get
the "No Sensors found!" error. I have followed the instructions that
sensors-detect has provided (except the /etc/rc* entries as I am not
sure which file to put the entries into, any?). 


I am using a Supermicro server with an Intel 857 chipset and the Super
P4SCA motherboard. Unfortunately I cannot look at the mother board as
the system is racked. 


Here is some of the information I have that may shed light to someone
who knows a thing or two about this stuff.

# Output of sensors-detect

 Detects correctly:

  * ISA bus address 0x0290 (Busdriver `i2c-isa')

    Chip `Winbond W83627HF Super IO Sensors' (confidence: 9)



 I will now generate the commands needed to load the I2C modules.

 Sometimes, a chip is available both through the ISA bus and an I2C bus.

 ISA bus access is faster, but you need to load an additional driver

 for it. If you have the choice, do you want to use the ISA bus or the

 I2C/SMBus (ISA/smbus)? Driver `w83627hf' (should be inserted):

  Detects correctly:

  * ISA bus address 0x0290 (Busdriver `i2c-isa')

    Chip `Winbond W83627HF Super IO Sensors' (confidence: 9)


To make the sensors modules behave correctly, add these lines to



#----cut here----

# I2C module options

alias char-major-89 i2c-dev

#----cut here----


To load everything that is needed, add this to some /etc/rc* file:


#----cut here----

# I2C adapter drivers

modprobe i2c-isa

# I2C chip drivers

modprobe w83627hf

# sleep 2 # optional

/usr/bin/sensors -s # recommended

#----cut here----


Any information would be greatly appreciated.
