OVERVIEW OF THE LM_SENSORS PACKAGE AND SUMMARY OF SUPPORTED DEVICES

This is the completely rewritten version of lm_sensors, a collection of
modules for general SMBus access and hardware monitoring. There are quite
a few changes compared with 1.x.y versions; 1.x.y versions are now officially
unsupported.

WARNING! Starting with lm_sensors version 2.5.0, only kernels 2.2.0 and
later are supported. Use lm_sensors version 2.4.5 if you use an older
kernel.

WARNING! If you downloaded this package through our CVS archive, you walk
the cutting edge. Things may not even compile! On the other hand, you will
be the first to profit from new drivers and other changes. Have fun!

WARNING! Many things have changed since version 2.4.0. Most importantly,
you need the i2c package.  It should have come bundled with lm_sensors,
but you may need to download it separately at:
  http://www.netroedge.com/~lm78
Users of kernel 2.3.34 and later (and also all soon to be 2.4.x) kernels
will be happy to know that the new I2C implementation has been included 
in the kernel; you may still need to patch it with the latest version 
if lm_sensors does not compile.

WARNING! The default module installation directory changed since version
2.2.1. If you don't change the directory in /etc/modules.conf (or
/etc/conf.modules), modprobe will probably load the wrong ones.

WARNING! Some things have changed since version 2.1.2. Most notably,
module piix4 is renamed i2c-piix4, module isa is renamed i2c-isa,
and module bit-mb is renamed i2c-via. You have been warned.

We could use some testers of hardware. If you own a specific monitoring
chip or I2C bus, and are willing to help us out, please contact us - even
if you did so before. Even if you have no programming knowledge, you could
help us by running new modules and reporting on the results and output. 
If you want to offer more substantial help, this is very welcome too, of
course.


Don't ask us whether we support a particular mainboard; we do not know.
We *do* know what hardware we support, but usually, it is easier to
install everything and run sensors-detect. It will tell you what hardware
you have (and incidentally, what corresponding drivers are needed). You
could also take a look at http://members.brabant.chello.nl/~a.vankaam/mbm
(this lists chips found on many mainboard, but regrettable, not the adapters
on them) or http://web01.fureai.or.jp/~hirobo/project/reserch_project.html
(yes, it is japanese; you want the ninth column, and it again lists only
chips, not adapters).


SMBus, also known as System Management Bus, is a protocol for communicating
through a I2C ('I squared C') bus. Many modern mainboards have a System
Management Bus. There are a lot of devices which can be connected to a
SMBus; the most notable are modern memory chips with EEPROM memories and
chips for hardware monitoring.

Most modern mainboards incorporate some form of hardware monitoring chips.
These chips read things like chip temperatures, fan rotation speeds and
voltage levels. There are quite a few different chips which can be used
by mainboard builders for approximately the same results.

Hardware monitoring chips are often connected to the SMBus, but often they
can also be connected to the ISA bus. The modules in this package usually
support both ways of accessing them.

Because the SMBus is just a special case of the generalized I2C bus, we
can simulate the SMBus protocol on plain I2C busses. These busses are
sometimes used in other parts of your computer. If a supported chip is
attached to one of these additional busses, they can be used too.

Please read INSTALL before trying to compile and install these modules.
There is a lot of additional documentation in the doc/ subdirectory.
Amnong these is a list of supported busses and chips. Regrettably, there
are too many mainboards to keep a list of busses and chips used on them.
On the other hand, we provide a program called 'sensors-detect' which
tries to figure out what hardware is available on your system.

The developers of this package can be reached through the email address
<sensors@stimpy.netroedge.com>. Do not hesitate to mail us if you have 
questions, suggestions, problems, want to contribute, or just want to 
report it works for you. But please try to read the documentation and\
FAQ first before you ask any questions!

The latest version of this package can always be found on our homepage:
http://www.netroedge.com/~lm78. Pre-release versions can be retrieved
through anonymous CVS; see doc/cvs for more information.

Note that at this moment, libsensors falls under the GPL, not the LGPL.
In more human language, that means it is FORBIDDEN to link any application
to the library, even to the shared version, if the application itself
does not fall under the GPL. This will probably be changed in the future.
In the meantime, you will have to contact us first if you want to do this.
