NAME
     it -- ITE IT8705F/12F/16F and SiS SiS950 Super I/O Hardware Monitor

SYNOPSIS
     device it0 at isa? port 0x290
     device it1 at isa? port 0xc00
     device it2 at isa? port 0xd00
     device it3 at isa? port 0x228

DESCRIPTION
     The it driver provides support for the IT8705F, IT8712F, IT8716F and
     SiS950 hardware monitors.  The values are exposed through the HW_SENSORS
     sysctl(3) interface.

     Most supported devices possess 15 sensors:

           Sensor    Units    Typical Use
           Fan0      RPM      CPU Fan
           Fan1      RPM      Fan
           Fan2      RPM      Fan

           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       CPU Temperature

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

HISTORY
     The it driver first appeared in OpenBSD 3.4 and was imported into
     DragonFly 1.11.

AUTHORS
     The it driver was written by Julien Bordet <zejames@greyhats.org>.  It
     was ported to FreeBSD by Constantine A. Murenin <cnst@FreeBSD.org> as a
     part of a Google Summer of Code 2007 project.

BUGS
     Interrupt support is unimplemented.
