Hi Jean

This is Chunhao.

Yes, you are right. 792D is an evolution of 791D. it is NOT a Super I/O.

Yes. I absolutely agree with you. I started a new driver for 792D,
which is w83792d.c, at least half of its function has been finished. 
I use W83781d.c as my reference, and delete all the codes related
with ISA, because 792D only be I2C.

OK, I see, thank you. I will send you mail using Plain Text format.

OK, I see, thanks.
