I have a Mac SE/30 that I want to get Linux or Some BSD on. The problem is that when it boots i get a little Disk with a ? in the middle (which I assume is the proverbal Operating System not Found for PC's). So realizing that the docs say I need MacOS for boot, does anyone know a way around booting macOS or a 'Mac 68k Rescue Disk', then some of the boot disk images for the little machine. Any Help appreciated.
