77
78 Voltage measured on the chip pin.
79
80 Actual voltage depends on the scaling resistors on the
81 motherboard, as recommended in the chip datasheet.
82
83 This varies by chip and by motherboard.
84 Because of this variation, values are generally NOT scaled
85 by the chip driver, and must be done by the application.
86 However, some drivers (notably lm87 and via686a)
87 do scale, because of internal resistors built into a chip.
88 These drivers will output the actual voltage. Rule of
89 thumb: drivers should report the voltage values at the
90 "pins" of the chip.
