I asked Chunhao Huang about it when he was working with us, but back then he didn't have the datasheet: http://lists.lm-sensors.org/pipermail/lm-sensors/2005-June/012754.html The main reason why we do not support this chip at the moment is simply the lack of datasheet. If you can publish it on Winbond's site and/or send it to me, we should be able to start working on proper support. I made the same assumption you did about the W83687THF chip: that it was probably similar to the W83627THF, given the similar names and release dates. If this is true, adding support to the w83627hf driver should be straightforward. The experimental patch I wrote several months ago may even be almost sufficient, at least to start with. > Quoting Jim: > > BTW - youd do well to drop the *misfortunate* posture. > I will try to tell my HW colleagues your dissatisfaction... > Thank you Jim ;) It really has nothing to do with the hardware itself. It's simply a matter of getting documentation about the chip. I can easily understand Steven's original position, it's always a bit worrying when you realize that your precious hardware lacks support, and he couldn't know how helpful Winbond is. Now that he knows, I'm sure he'll see the life in a much more positive way :) -- Jean Delvare
