First of all I would like to say that I admire the work you are doing.
I think lm_sensors is extremely important to Linux. Thanks for your
efforts.
Now on to my problem...
I am having trouble getting the output from the w83781d module to make
sense.
lm_sensors version: 2.8.1
Fedora Core 1 Kernel: 2.4.22-1.2199.nptlsmp

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 module
for it. If you have the choice, do you want to use the ISA bus or the
I2C/SMBus (ISA/smbus)? smbus
To make the sensors modules behave correctly, add these lines to
/etc/modules.conf:
#----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-piix4
modprobe i2c-isa
# I2C chip drivers
modprobe adm1021
modprobe eeprom
modprobe w83781d
# sleep 2 # optional
/usr/local/bin/sensors -s # recommended
#----cut here----
My setup is below. I did not load the eeprom module. I do not think I
need what it provides. I really just want tempuratures and fan speeds.
modprobe i2c-piix4
modprobe i2c-isa
modprobe w83781d
modprobe adm1021
Output from sensors. As you can see w83781d reports an odd looking
temperature. Specifically the +208.0?C. Actually, I am not sure what
temp1 and 2 are for. I guess I expect the output to look more like the
adm1021 module. I am hoping I can get all readings from the
w83781d-isa-0290 section. I am a bit of a minimalist and I think the
adm1021 module may be causing a problem.

My sensors config is attached.
Of course above I have mentioned a couple of possible issues with the
adm1021 and the eeprom module. I don't want to delve into those
problems until I can give you a little bit better info, hopefully soon.
Thanks,
Chris Lopeman
