I have the blockchain synced, and then tried to run geth --rpc --support-dao-fork. I got a message saying that --support-dao-fork is unsupported command. So I have run geth --rpc --syncmode "fast" --verbosity 3 --cache=1024 and then Running etherminer -G from cpp-etherum it downloads the DAG and starts to mine. geth is committing the work to the blockchain.
Has the --support option been depreciated or am I mining ETC instead of post fork Eth by default?
