if you want to use latest version of Barry Allen you must to use unstable cvs and if you want to install stable version of cvs you need to Barry Allen 12.47
Thank you all for your information! I have tried all the stable and unstable DM 7080 images with all versions of Barry Allen on both the Sd Card, USB and HDD and I have not been able to install multiboot. I do not know what to do anymore!
