Damn, I can't much help you there then. I haven't been playing around long enough to figure out non-GPU usage.
When I said input, I mean this:
minerd.exe
[certain variables that tell the mining program what to do with your GPU/CPU] -o stratum+tcp://doge.scryptpools.com:3333 -u USERNAME.WORKER_ID -p PASSWORD
I can't tell you off the top of my head what those variables would be, because idk how to mine with just a CPU. It is also very dependent on your personal setup from my understanding.
Maybe try googling "CPU mining bitcoin/dogecoin/litecoin" whatever it is you want to mine. I am currently mining dogecoin and litecoin, it seems that those are the only two you will get any return out of unless you have a Hulk smash gaming rig.
Try using the prompt for a CPU (make sure you add .exe to minerd, idk why it leaves that out)
here
That config is designed for mining in a pool with other members of that site, but you can replace the info with the server you have.
Make sure you save the notepad file as a .bat file once you are done editing the configuration.
Inshallah this helps you.
