1   Introduction

I have bught an ABIT VP6 motherboard with two Intel Pentium III coppermine processors that I intend to overclock. But to do that in a nice way you (I) have to have control over the temprature. The motherboard supports that and this is how you can access the information in debian linux.

2   Packages

Theese are the packages that are needed. And all packages that they depend on (not listed)

lm-sensors	The tool to use to see the sensors.
lm-sensors-source	To build the kernel modules.
kernel-source-2.4.4	Needed by some reason, I do not know why.

3   Recompile

Something like this, I do not really remember.

3.1   Kernel

This package needs an unpacked kernel, with the .config used to create the kernel and some header files created when the kernel compiles. I do not know where you can stop the kernel compile but somewhere in the middle maybe. You can of course change the kernel version 2.4.4 below with some other kernel version (like 2.4.5 :)

cd /usr/src
apt-get source kernel-image-2.4.4-686-smp
apt-get install kernel-source-2.4.4
tar xfj kernel-source-2.4.4.tar.bz
cd kernel-source-2.4.4
cp ../kernel-image-2.4.4/config/686-smp .config
make-kpkg --revision smp1 binary

If you do not want to compile the entire kernel use this like instead of the make-kpkg line.

make modules (and then you can breake it when the first gcc runs...)

3.2   kernel modules

You have to recompile the lm-sensors-source package to get some kernel modules.

See the /usr/share/doc/lm-sensors-source/README.Debian document.

cd /usr/src
ln -s kernel-source-2.4.4 linux
tar xfz lm-sensors.tar.gz
cd modules/lm-sensors
debian/rules KVERS=2.4.4-686-smp binary-modules KSRC=/usr/src/kernel-source-2.4.4

The KSRC is not needed if you have made a linux link...

Now you should have a /usr/src/lm-sensors-2.4.4-686-smp_2.5.4+_i386.deb that you can install.

4   Configure

The tool sensors-detect tool helps you out to configure things properly. It will tell you what to do, and it told me to do this (NOTE it does not update the system, just tell you what to do). So if you want to do it by hand, you can do like this:

• Add 'alias char-major-89 i2c-dev' to the module conf file. This is best done by creating a file in /etc/modutils/ and then run update-modutils.
• Run: modprobe i2c-isa and modprobe via686a, or add i2c-isa and via686a to the /etc/modules file.

5   Usage

Run: 'sensors' and you will get some nice information.
