Is it possible to program the AntMiner S9 or other ASIC miners?
For example, let's say I only want it to try nonces from 1 to 1 million (instead of all 4 billion possibilities) would it be possible to somehow modify the software on the machine to do this? (please don't ask me why I want to do this, I just want to know if something like this is possible)
If it's possible, what programming language would I use?
Finally, would doing this (significantly) reduce the hash rate of the miner?
