Well the version of Minepeon I am using has both options of using bfgminer or cgminer and it shows some coding above the selection but I dont know coding so I wouldnt have any idea how to tell it how to use the antminer or the red bitfurys. Currently I am using cgminer on my pc (Windows 8.1) with the antminer, and bfgminer with my 4 red bitfurys. Are you sure I have to change OS or can I fix this somehow?
The issue I had with minepeon was that some of the second function keys wouldn't seem to work on it. I had to compile a version of cg miner that accepted my antminers. I know people who are using block errupters and ants had to compile 2 seperate versions of cg miner in order to get them both working. I'm not sure if you can do this with minepeon as it is basically only an operating system. It shouldnt be too much of an issue though if you have to compile to cgminer versions as they'll both be contributing to the same mining account so you won't lose out, you'll just probably have to set up a new worker on your mining pool to accommodate the two different types of miners you have.
I'm still all new to this too but this is what I've picked up along the way so I may be way off.
