The Minix implementation on the Amiga does not use Exec or any part of the Amiga operating system. It takes over the machine at all levels. It can't use the existing device drivers, for example, because Exec must be running. Exec would make a good base for a Unix-like "OS" but not from an educational aspect, which is why they decided not to use it... can't play with scheduling algorithyms and whatnot. So it rujns standalone. You gain Atari/Minix 100.0% disk compatibility, but lose your Amiga for the duration. Deven -- Deven T.
