Sorry, should have included that.   I think I can figure out computation
factors, if I can figure out which BIOS voltage maps to which sensors
voltage...  but since they're in different orders and there aren't the same
number of them, I'm a bit confused.



nct6775-isa-0290
Adapter: ISA adapter
VCore:         +0.90 V  (min =  +0.50 V, max =  +1.74 V)
+12V:          +1.10 V  (min =  +2.04 V, max =  +2.04 V)   ALARM
AVCC:          +3.41 V  (min =  +2.98 V, max =  +3.63 V)
+3.3V:         +3.41 V  (min =  +3.14 V, max =  +3.47 V)
+5V:           +1.06 V  (min =  +2.04 V, max =  +2.04 V)   ALARM
+1.3V:         +1.06 V  (min =  +1.17 V, max =  +1.43 V)   ALARM
VSB:           +3.42 V  (min =  +2.98 V, max =  +3.63 V)
VBAT:          +3.38 V  (min =  +2.40 V, max =  +3.60 V)
fan1:          594 RPM  (min =    0 RPM, div = 32)  ALARM
fan2:         1054 RPM  (min =    0 RPM, div = 32)  ALARM
fan3:          629 RPM  (min =    0 RPM, div = 32)  ALARM
fan4:            0 RPM  (div = 128)
SYSTIN:        +29.0°C  (high =  +0.0°C, hyst =  +0.0°C)  ALARM  sensor =
diode
CPUTIN:        +29.0°C  (high = +80.0°C, hyst = +75.0°C)  sensor = diode
PECI Agent 0:  +38.0°C  (high = +80.0°C, hyst = +75.0°C)  sensor = diode
PCH_CHIP_TEMP: +45.0°C
PECI Agent 1:   +0.0°C  (high = +80.0°C, hyst = +75.0°C)
cpu0_vid:     +2.050 V
