What do you mean by bridge? The temp reading comes straight from the CPU. There's an internal thermal diode in the CPU that's connected to the vt1211. There's no bridge involved here. It's only a function of the CPU thermal diode properties (which are unknown for Nehemiah, at least to me). ...juerg > Regards, > > c. >
