52     Use 'init=0' to bypass initializing the chip.
57     The driver used to reset the chip on load, but does no more. Use
62   a certain chip. Typical usage is `force_subclients=0,0x2d,0x4a,0x4b`
63   to force the subclients of chip 0x2d on bus 0 to i2c addresses

75 The Asus chips are similar to an I2C-only W83782D.

96 The W8378* implements temperature sensors (three on the W83781D and W83782D,
101 Temperatures are measured in degrees Celsius. There is always one main
102 temperature sensor, and one (W83783S) or two (W83781D and W83782D) other
106 can be found by setting the Hysteresis value to +127 degrees Celsius; in
107 this case, alarms are issued during all the time when the actual temperature
111 For the other temperature sensor(s), an alarm is triggered when the
112 temperature gets higher then the Overtemperature Shutdown value; it stays
113 on until the temperature falls below the Hysteresis value. But on the
115 Temperatures are guaranteed within a range of -55 to +125 degrees. The
116 main temperature sensors has a resolution of 1 degree; the other sensor(s)
139 The W83782D and W83783S temperature conversion machine understands about
140 several kinds of temperature probes. You can program the so-called
178 miss once-only alarms.

251   We are sorry that the calculation for R-T table value is
253   to calculate the R-T table for you. But you should give us real R-T
