It might work. I haven't really looked at it carefully >though. I hate to ask a flippant question, but: "why not?" Surely the Minix community is more than just students taking their first OS course. For myself, I'm considering trying Minix, but am also discouraged by this archaic lack virtual memory. Note also that more advanced OS courses might use a future Minix to study user-level VM primitives and the ideas like those in Mach. regards, Mark
