KI2 boards can ONLY be KI2 because of the harddrive controller IC. KI1's can be converted into KI2 with the extra PCB mounted to the harddrive slot. I have made a KI2 into a KI1 but I had to unsolder the harddrive controller IC and replace it with one from a KI1. (NOT fun, surface mount parts with weak traces that come up easily)
