| 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. |
