Edit /etc/modules.conf and add to it the following lines:
alias char-major-89 i2c-dev
options it87 temp_type=0x31
now:
modprobe i2c-proc
modprobe it87
modprobe i2c-isa
sensors
should output you some data
When it works, you can write it to a file, that will be loaded automatically on
boot. Under
SuSE the file is:
/etc/init.d/boot.local (used to be /sbin/init.d/)
and you should just add: sensors -s
Under mandrake, the install should have created that file:
/etc/init.d/sensors, which you can edit freely, sensord being just a
daemon to watch over temperature and fan speed, I assume no one
will need something like that for her/his own machine.
Paolo reports that in order to start up sensord on boot, he put in /etc/sysconfig/sensors:
MODULE_0=i2c-proc
MODULE_1=it87
MODULE_2=i2c-isa
Now as root you should edit your /etc/sensors.conf
search for that line: chip "it87-*"
and below you should be able to modify everything to get the right data, here is
a copy of what i have in there:
(please note that temp1 is trash and only temp2 and temp3 should be kept)
This time you'll be forced to compile the modules.
install the source and programs:
apt-get install lm-sensors lm-sensors-source
The upstream lm-sensors maintainers know of a problem using
lm-sensors with IBM ThinkPad computers, resulting in
firmware corruption. If you are installing this package on
a ThinkPad, you should wait until the upstream maintainers
have solved this problem before building modules from it.
For more information, see
/usr/share/doc/lm-sensors-source/README.thinkpad.
IBM ThinkPad brokenness -- really install lm-sensors?
Answer yes to this question, you can't have an IBM thinkpad and the k7s5a in the same box as far as I know!
cd /usr/src
tar xzvf lm-sensors.tar.gz
cd modules/lm-sensors/
make && make install
Then you should have modutils take a few arguments,
the best way is probably to use a new file, like:
/etc/modutils/sensors
with this content:
alias char-major-89 i2c-dev
options it87 temp_type=0x31
run
update-modules
modprobe i2c-isa it87
You can now type sensors to access to the informations (note that you should edit sensors.conf, otherwise you'll see strange and inaccurate things :] )
You can also put i2c-isa and it87 in /etc/modules (one by line!) to have them be automatically loaded on boot, I don't know yet, how/whether it is possible to use some automatic loading/removing process with /etc/modules.conf
