I'll have a look at your driver at some point. To tell you the truth, the VRM and VID is NOT important to me, I can omit it in my w83792d.c, but since there are w83781d_vrm() and w83781d_vid() in w83781d.c, I also add two function w83792d_vrm() and w83792d_vid() into w83792d.c. their function maybe incomplete now, so I sent you the above mail to ask you about it. ;-) One of my managers will send you a rough version of 792 driver today or tomorrow, then please give me more information about it after your review to my source. And if there are some bugs in 792 driver please tell us. :-) > Now for my own question to you: I have a w83791sd on my mainboard. > Will you publish a better datasheet for that one?

As to this question, I have asked the help of my manager, he will give me the answer in the near future, then I will send mail to you. Would you please tell me the version number of your available w83791sd data sheet? So that we can know whether it has been updated.
