ah Bitmain finally put up the new firmware so the S9 will work with NICEHASH. Except when you try to use p=? and the password line!!! at least you can hash now.
All of them you just have to match the ? MHZ located on your S9 hash board and download the one that matches your miner. 500 , 600 , 650 MHZ depending which one you have.
