ok, sorry for misremembering rather than checking the datasheet. A separate driver sounds good. I'll put an ID for you in i2c-id.h but it really isn't used for anything. When you have a patch posted somewhere let us know and we'll put a link to it on our new drivers page. mds Tomas Holmqvist wrote: > In the functional diagram of the chip there's no connections between > the SuperIO parts and the HMB, There's no mention of any registers in > the LPC interface holding voltage/temp values and there's even the > sentences: > > "It should be noted that there are two main interfaces used to access > the components of this chip.
