32 Initialize the I2C address of the sensors
35 Use 'init=0' to bypass initializing the chip.
36 Try this if your computer crashes when you load the module.
41 This driver implements support for ISA accesses *only* for
42 the Winbond W83627HF, W83627THF, W83697HF and W83637HF Super I/O chips.
43 We will refer to them collectively as Winbond chips.
45 This driver supports ISA accesses, which should be more reliable
46 than i2c accesses. Also, for Tyan boards which contain both a
47 Super I/O chip and a second i2c-only Winbond chip (often a W83782D),
48 using this driver will avoid i2c address conflicts and complex
49 initialization that were required in the w83781d driver.
51 If you really want i2c accesses for these Super I/O chips,
52 use the w83781d driver. However this is not the preferred method
53 now that this ISA driver has been developed.
55 The `w83627_HF_` uses pins 110-106 as VID0-VID4. The `w83627_THF_` uses the
56 same pins as GPIO[0:4]. Technically, the `w83627_THF_` does not support a
57 VID reading. However the two chips have the identical 128 pin package. So,
58 it is possible or even likely for a w83627thf to have the VID signals routed
59 to these pins despite their not being labeled for that purpose. Therefore,
60 the w83627thf driver interprets these as VID. If the VID on your board
61 doesn't work, first see doc/vid in the lm_sensors package[1]. If that still
62 doesn't help, you may just ignore the bogus VID reading with no harm done.
64 For further information on this driver see the w83781d driver documentation.

71 The driver used to have a module parameter named force_addr, which could
72 be used to force the base I/O address of the hardware monitoring block.
73 This was meant as a workaround for mainboards with a broken BIOS. This
74 module parameter is gone for technical reasons. If you need this feature,
75 you can obtain the same result by using the isaset tool (part of
76 lm-sensors) before loading the driver:
78 # Enter the Super I/O config space::
80 isaset -y -f 0x2e 0x87
81 isaset -y -f 0x2e 0x87
83 # Select the hwmon logical device::
85 isaset -y 0x2e 0x2f 0x07 0x0b
87 # Set the base I/O address (to 0x290 in this example)::
89 isaset -y 0x2e 0x2f 0x60 0x02
90 isaset -y 0x2e 0x2f 0x61 0x90
92 # Exit the Super-I/O config space::
94 isaset -y -f 0x2e 0xaa
96 The above sequence assumes a Super-I/O config space at 0x2e/0x2f, but
97 0x4e/0x4f is also possible.
102 Here is a summary of the voltage pin mapping for the W83627THF. This
103 can be useful to convert data provided by board manufacturers into
104 working libsensors configuration statements:
110 ======== =============== =============== ===============
111 Pin Name Register Sysfs attribute
112 ======== =============== =============== ===============
118 61 5VSB 50h (bank 5) in7
119 74 VBAT 51h (bank 5) in8
120 ======== =============== =============== ===============
122 For other supported devices, you'll have to take the hard path and
123 look up the information in the datasheet yourself (and then add it
124 to this document please.)
