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. | |

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. | |

64 | For further information on this driver see the w83781d driver | |
65 | documentation. | |
