ELKS is a subset of the Linux kernel that runs on IBM compatible PCs from 8086 up. It is intended to get use out of obsolete old hardware, for use in embedded systems, and as an educational tool. ELKS has been moved to Github to protest SourceForge's installer adware hijacking. This does not directly affect ELKS, but it does affect many major open source projects such as Gimp and FileZilla by attempting to trick the user into installing adware in order to download these programs.
