28 | Module Parameters | ||
29 | ----------------- | ||
30 | |||
31 | * force_addr: int | ||
32 | Initialize the ISA address of the sensors | ||
33 | * force_i2c: int | ||
34 | Initialize the I2C address of the sensors | ||
35 | * init: int | ||
36 | (default is 1) | ||
37 | Use 'init=0' to bypass initializing the chip. | ||
38 | Try this if your computer crashes when you load the module. | ||
39 | |||
40 | Description | ||
41 | ----------- | ||
42 | |||
43 | This driver implements support for ISA accesses *only* for | ||
44 | the Winbond W83627HF, W83627THF, W83697HF and W83637HF Super I/O chips. | ||
45 | We will refer to them collectively as Winbond chips. | ||
46 | |||
47 | This driver supports ISA accesses, which should be more reliable | ||
48 | than i2c accesses. Also, for Tyan boards which contain both a | ||
49 | Super I/O chip and a second i2c-only Winbond chip (often a W83782D), | ||
50 | using this driver will avoid i2c address conflicts and complex | ||
51 | initialization that were required in the w83781d driver. | ||
52 | |||
53 | If you really want i2c accesses for these Super I/O chips, | ||
54 | use the w83781d driver. However this is not the preferred method | ||
55 | now that this ISA driver has been developed. | ||
56 | |||
57 | Technically, the w83627thf does not support a VID reading. However, it's | ||
58 | possible or even likely that your mainboard maker has routed these signals | ||
59 | to a specific set of general purpose IO pins (the Asus P4C800-E is one such | ||
60 | board). The w83627thf driver now interprets these as VID. If the VID on | ||
61 | your board doesn't work, first see doc/vid in the lm_sensors package. If | ||
62 | that still doesn't help, email us at lm-sensors@lm-sensors.org. | ||
63 | |||
64 | For further information on this driver see the w83781d driver | ||
65 | documentation. | ||
