This is the completely rewritten version of lm_sensors, a collection of |
|---|
| 2 |
modules for general SMBus access and hardware monitoring. There are quite |
|---|
| 3 |
a few changes compared with 1.x.y versions; read doc/version-2 for the |
|---|
| 4 |
most interesting ones. |

WARNING! If you downloaded this package through our CVS archive, you walk |
|---|
| 7 |
the cutting edge. Things may not even compile! On the other hand, you will |
|---|
| 8 |
be the first to profit from new drivers and other changes. Have fun! |
|---|
| 9 |
|
|---|
| 10 |
WARNING! The default module installation directory changed since version |
|---|
| 11 |
2.2.1. If you don't change the directory in /etc/modules.conf (or |
|---|
| 12 |
/etc/conf.modules), modprobe will probably load the wrong ones. |
|---|
| 13 |
|
|---|
| 14 |
WARNING! Some things have changed since version 2.1.2. Most notably, |
|---|
| 15 |
module piix4 is renamed i2c-piix4, module isa is renamed i2c-isa, |
|---|
| 16 |
and module bit-mb is renamed i2c-via. You have been warned. |
|---|
| 17 |
|
|---|
| 18 |
At least the following SMBus adapters are supported: |
|---|
| 19 |
Intel PIIX4 (used in most Intel chipsets) |
|---|
| 20 |
Acer Labs M1541 and M1543C (used in the Aladdin IV, V and Pro 2 chipsets) |
|---|
| 21 |
VIA Technologies 82C586B (used in most VIA chipsets) |
|---|
| 22 |
|
|---|
| 23 |
At least the following hardware sensor chips are supported: |
|---|
| 24 |
National Semicoductor LM75, LM78, LM78-J, LM79 and LM80 |
|---|
| 25 |
Winbond W83781D, W83782D and W83783S |
|---|
| 26 |
Genesys Logic GL518SM (several revisions) |
|---|
| 27 |
Analog Devices ADM1021 and ADM9240 |
|---|
| 28 |
SiS Southbridge (integrated in the chipset; the I2C adapter will also be |
|---|
| 29 |
supported in the near future) |
|---|
| 30 |
Maxim MAX1617 and MAX1617A |
|---|
| 31 |
Dallas Semiconductor DS1780 |
|---|
| 32 |
Hewlett Packard Maxilife (several revisions) |
|---|
| 33 |
|
|---|
| 34 |
We also support some miscellaneous chips: |
|---|
| 35 |
Linear Technologies LTC1710 |
|---|
| 36 |
Dimms with EEPROMs |
|---|
| 37 |
|
|---|
| 38 |
We could use some testers of hardware. If you own a specific monitoring |
|---|
| 39 |
chip or I2C bus, and are willing to help us out, please contact us - even |
|---|
| 40 |
if you did so before. Even if you have no programming knowledge, you could |
|---|
| 41 |
help us by running new modules and reporting on the results and output. |
|---|
| 42 |
If you want to offer more substantial help, this is very welcome too, of |
|---|
| 43 |
course. |

SMBus, also known as System Management Bus, is a protocol for communicating |
|---|
| 47 |
through a I2C ('I squared C') bus. Many modern mainboards have a System |
|---|
| 48 |
Management Bus. There are a lot of devices which can be connected to a |
|---|
| 49 |
SMBus; the most notable are modern memory chips with EEPROM memories and |
|---|
| 50 |
chips for hardware monitoring. |
|---|
| 51 |
|
|---|
| 52 |
Most modern mainboards incorporate some form of hardware monitoring chips. |
|---|
| 53 |
These chips read things like chip temperatures, fan rotation speeds and |
|---|
| 54 |
voltage levels. There are quite a few different chips which can be used |
|---|
| 55 |
by mainboard builders for approximately the same results. |
|---|
| 56 |
|
|---|
| 57 |
Hardware monitoring chips are often connected to the SMBus, but often they |
|---|
| 58 |
can also be connected to the ISA bus. The modules in this package usually |
|---|
| 59 |
support both ways of accessing them. |
|---|
| 60 |
|
|---|
| 61 |
Because the SMBus is just a special case of the generalized I2C bus, we |
|---|
| 62 |
can simulate the SMBus protocol on plain I2C busses. These busses are |
|---|
| 63 |
sometimes used in other parts of your computer. If a supported chip is |
|---|
| 64 |
attached to one of these additional busses, they can be used too. |
|---|
| 65 |
|
|---|
| 66 |
Please read INSTALL before trying to compile and install these modules. |
|---|
| 67 |
There is a lot of additional documentation in the doc/ subdirectory. |
|---|
| 68 |
Amnong these is a list of supported busses and chips. Regrettably, there |
|---|
| 69 |
are too many mainboards to keep a list of busses and chips used on them. |
|---|
| 70 |
On the other hand, we provide a program called 'sensors-detect' which |
|---|
| 71 |
tries to figure out what hardware is available on your system. |
|---|
| 72 |

|---|
| 73 |
