The instructions in this document will generally work if you have a standard |
|---|
| 5 |
system, but not always!! |
|---|

|
|---|

The first part of document is for 2.6 kernel series, second part is for |
|---|
| 8 |
older 2.4 kernels. |

Quickstart for Kernel 2.6 |
|---|
| 11 |
------------------------- |
|---|
| 12 |
|
|---|
| 13 |
0) Just compile and install lm-sensors userspace tools. You can do that with: |
|---|
| 14 |
'make user; make user_install' |
|---|
| 15 |
1) Make sure your kernel has support for all I2C bus drivers and |
|---|
| 16 |
'i2c device interface'. If you are using a distribution kernel, all is |
|---|
| 17 |
already prepared, you don't need to recompile it. |
|---|
| 18 |
2) Run 'sensors-detect' command, it will tell you what modules you need to load. |
|---|
| 19 |
3) Load them and run 'sensors' command, you should see some results. |
|---|
| 20 |
4) Find right section in /etc/sensors.conf, fix labels, limits, fan divisors |
|---|
| 21 |
5) Run 'sensors -s' to apply the changes. |

Quickstart for Kernel 2.4 |
|---|
| 31 |
------------------------- |
|---|
| 32 |
|
|---|
| 33 |
NOTE: PLEASE SKIM THE INSTALL DOCUMENT, OR BETTER YET READ IT CAREFULLY! |
|---|
| 34 |
|
|---|
| 35 |
Quickstart for i2c option 1 (modules) and lm_sensors option 1 (modules). |
|---|
| 36 |
This is by far the EASIEST METHOD. |
|---|
| 37 |
Other methods are described in INSTALL. |
|---|

* Verify you are running a 2.4 kernel, 2.4.10 or later. |
|---|
| 41 |
|
|---|
| 42 |
* Make sure you have the kernel tree corresponding to your current |
|---|
| 43 |
kernel in /lib/modules/$(uname -r)/build. |
|---|
| 44 |
Even if the source is there, it may not correspond to your running |
|---|
| 45 |
kernel. If so, you will have to recompile your kernel. |
|---|
| 46 |
|
|---|
| 47 |
* Verify that your i2c support in the kernel is configured as |
|---|
| 48 |
modules or is disabled. If it is compiled-in, you obviously |
|---|
| 49 |
cannot replace it with modules in the next step. |
|---|
| 50 |
|
|---|
| 51 |
* Do `lsmod'. If there are any old i2c or sensors modules loaded, |
|---|
| 52 |
you MUST remove them (as root) with `rmmod'. |
|---|
| 53 |
|
|---|
| 54 |
* Download, build, and install the latest i2c package, |
|---|
| 55 |
(i2c-2.9.0 or later). The i2c subsystem found in the Linux 2.4 |
|---|
| 56 |
kernel trees, even the latest ones, is outdated and won't work. |
|---|
| 57 |
Quickstart for i2c: make; (as root) make install |
|---|
| 58 |
|
|---|
| 59 |
* Go back to the lm_sensors directory. Do `make'. |
|---|
| 60 |
The warnings about .d files at the start are harmless. |
|---|
| 61 |
|
|---|
| 62 |
* Do (as root) `make install'. |
|---|
| 63 |
|
|---|
| 64 |
* Verify that /usr/local/lib is listed in /etc/ld.so.conf; |
|---|
| 65 |
if it isn't, add it, then run (as root) `ldconfig'. |
|---|
| 66 |
|
|---|
| 67 |
* Run (as root) `prog/mkdev/mkdev.sh' to create the device files, |
|---|
| 68 |
unless you already have them or are running devfs or udev. |
|---|
| 69 |
|
|---|
| 70 |
* Run (as root) `prog/detect/sensors-detect' to detect your hardware, |
|---|
| 71 |
put the lines it suggests into /etc/modules.conf, and run all |
|---|
| 72 |
the commands it suggests (`modprobe X', `sensors -s'). |
|---|
| 73 |
|
|---|
| 74 |
* Run `sensors' to see your output. |
|---|
| 75 |
|
|---|
| 76 |
* That's it! If you have problems, read our excellent FAQ |
