Problem with super io NCT6793D

[王翔]

I want to porting coreboot to MSI's motherboard.
However, the super io of this motherboard is the NCT6793D. 
Which chip is like NCT6793D? Or give me datasheet of the NCT6793D. 
Thank you very much.

Run 'util/superiotool -Vd' to read the chip ID, should show something like
0xd120. If you then modify the entry of NCT6791D (id=0xc803 in nuvoton.c)
you should get some register dumps out for NCT6793D. You can compare those
against NCT6791D datasheet or post them on the list.

You can inquire about the datasheet at Nuvoton 
They are usually very responsive.
