It can run Linux, AmigaOS and a wide range of MorphOS versions. Currently a firmware ROM image is needed to boot and only MorphOS has a video driver to produce graphics output. Linux could work too but distros that supported this machine don't include usual video drivers so those only run with serial console for now.
