Mesa CFG

Looking for some direction or hints on setting up my lathe.
I've bought a 6i25+7i76 and now I've added a 7i85s. Used mesaflash with the 5i25_7i76_7i85s.bit.
Where is a good starting point for learning how to configure HAL?

I think the easiest way is to use pncconf to create a standard open loop 7I76 step/dir config
and then and encoder feedback by hand to the hal file.
