sorry about the subject, my mistake :-(
below are the outputs from the commands requested.
I would like to attempt to activate the bus as it would be handy considering
I work in hot environments a lot.
if its too risky can I still use the temp sensor in the hard drive as this
is what I previously used in M$ windows
thank you for your assistance and valuable time

Hi John :)
please excuse any fumbling questions as I am new to Linux
It is OK to ask, but nexttime dont forget to include proper subject please :)
sensors-detect failed to see my SMbus, I have a Dell Inspiron 8500
laptop with an Intel 82801 DBM SMbus controller (ICH4-M)
my question is do I use/will the i801 driver work? and what is the best
way to get it to work?
Yes there are ways to do it but on notebooks the chips for temp monitoring are
So even if we forcibly enable it (this is somewhat bit dangerous) there will be
no chip detected.
would Ilja Rauhut's p4b hack do the trick?
For kernel 2.4.x perhaps yes.
For kernel 2.6.x you need to take a look to pci/quirks.c
If you want to know your CPU temo you can try to get it from ACPI.
Just issue command acpi -V and you should see something.
If you really want to enable the bus I would need to know what kernel version y
and output of:
But I can nearly guarantee there will be no sensor found.
