NAME
     it - ITE IT8705F, IT8712F, and SiS SiS950 temperature, voltage, and fan
     sensor

SYNOPSIS
     it0 at isa? port 0x290
     it1 at isa? port 0xc00
     it2 at isa? port 0xd00

DESCRIPTION
     The it driver provides support for the IT8705F, IT8712F and SiS950 hard-
     ware monitors to be used with the sysctl(8) interface.

     Most supported devices possess 15 sensors:

           Sensor    Units    Typical Use
           Fan0      RPM      CPU Fan
           Fan1      RPM      Fan
           Fan2      RPM      Fan
           IN0       uV DC    Core voltage
           IN1       uV DC    Core voltage
           IN2       uV DC    +3.3V
           IN3       uV DC    +5V
           IN4       uV DC    +12V
           IN5       uV DC    Unknown
           IN6       uV DC    -12V
           IN7       uV DC    -5V
           IN8       uV DC    VBAT
           Temp      uK       Motherboard Temperature
           Temp      uK       Motherboard Temperature
           Temp      uK       CPU Temperature

     For some devices, sensors' names and numbers will be different.
