EthOS is very popular mining distro. Please find the basic set up for the most important pools. You could easily set up any other pool just changing the host:port address. Please go to "How to start" section of the pool if you are not sure which miner you need to use.
Dagger Hashimoto Ethminer:
Starting from 1.3.2 version of EthOS please add "stratum1+tcp://" in front of the pool and change "stratumproxy enabled" to "stratumproxy miner".
