Module Parameters
|
||
|
|
-----------------
|
||
|
|
|
||
|
|
* force_addr: int
|
||
|
|
Initialize the ISA address of the sensors
|
||
|
|
* force_i2c: int
|
||
|
|
Initialize the I2C address of the sensors
|
||
|
|
* init: int
|
||
|
|
(default is 1)
|
||
|
|
Use 'init=0' to bypass initializing the chip.
|
||
|
|
Try this if your computer crashes when you load the module.

Description
|
||
|
|
-----------
|
||
|
|
|
||
|
|
This driver implements support for ISA accesses *only* for
|
||
|
|
the Winbond W83627HF, W83627THF, W83697HF and W83637HF Super I/O chips.
|
||
|
|
We will refer to them collectively as Winbond chips.
|
||
|
|
|
||
|
|
This driver supports ISA accesses, which should be more reliable
|
||
|
|
than i2c accesses. Also, for Tyan boards which contain both a
|
||
|
|
Super I/O chip and a second i2c-only Winbond chip (often a W83782D),
|
||
|
|
using this driver will avoid i2c address conflicts and complex
|
||
|
|
initialization that were required in the w83781d driver.
|
||
|
|
|
||
|
|
If you really want i2c accesses for these Super I/O chips,
|
||
|
|
use the w83781d driver. However this is not the preferred method
|
||
|
|
now that this ISA driver has been developed.
|
||
|
|
|
||
|
|
Technically, the w83627thf does not support a VID reading. However, it's
|
||
|
|
possible or even likely that your mainboard maker has routed these signals
|
||
|
|
to a specific set of general purpose IO pins (the Asus P4C800-E is one such
|
||
|
|
board). The w83627thf driver now interprets these as VID. If the VID on
|
||
|
|
your board doesn't work, first see doc/vid in the lm_sensors package. If
|
||
|
|
that still doesn't help, email us at lm-sensors@lm-sensors.org.
|
||
|
|
|
||
|
|
For further information on this driver see the w83781d driver
|
||
|
|
documentation.
