Port is not done yet. I am new to system development and still waiting for system to arrive and for response from quanta. I wonder will they send me requested datasheets? 

I have downloaded bios update utility from lenovo and it seems this computer is running modified phoenix bios. I will try to play a little bit with that when board will be there. Roda rk9 seems to be quite similar except superio. 

As i said this is quite new area of my interest so i have little experience.
