I a dreaming about a special Super I/O driver which would provide services for devices on the chip. Super I/O bases addresses are far more stable (hardwired to a few choices) than base addresses of their devices (freely programmable). > I have three questions though: > 1.

Unfortunately ITE does not provide public datasheets. We could pick up some new bits from the Linux driver though. http://lxr.linux.no/#linux+v3.6.2/drivers/hwmon/it87.c > 2.

Again, this would require more knowledge about the chip. Plus some additional knowledge about the motherboard. BTW, you could try to use some Linux live CD and see what gets reported there. Maybe they've already figured out the correct mapping. > 3. When will the it module be included with the FreeBSD? Soon, I hope.

Can't > verify whether the voltages are correct due to my limited knowledge. Voltages are the most tricky ones as for many of them there are resistor dividers. There are some recommendations on what resistors to use, but only a motherboard vendor knows for sure what's there (or maybe some guesses could be made by studying the motherboard with a magnifying glass). Thank you very much for bearing with me and doing all the hard work! BTW, in the driver code there is a place with the following comment: /* XXX perhaps >= ? */ Could you please try to use >= instead of == there? -- Andriy Gapon
