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.
