I have a Tyan Tomcat i810ef S2460 that has the ITE IT8712F chip.
The it87 entry doesn't work for me in the default sensors.conf
mine is attached.
Also, it seems the sensors are in diode mode on that board
(at least cpu1 is) so I had to add
options it87 temp_type=0x3

# The next two are negative voltages (-12 and -5).
# The following formulas must be used. Unfortunately the datasheet
# does not give recommendations for Rin, Rf, but we can back into
# them based on a nominal +2V input to the chip, together with a 4.096V Vref.
# Formula:
# actual V = (Vmeasured * (1 + Rin/Rf)) - (Vref * (Rin/Rf))
# For -12V input use Rin/Rf = 4.14 (232/56)
# For -5V input use Rin/Rf = 2.14 (120/56)
# Then you can convert the forumula to a standard form like:
