What hardware architectures is AROS available for?
Currently AROS is available in a quite usable state as native and hosted (under Linux, FreeBSD and NetBSD) for the i386 architecture (ie. IBM PC AT compatible clones) and hosted (Linux and NetBSD) for the m68k architecture (eg. the Amiga, Atari and Macintosh). There are ports under way at varying degrees of completeness to SUN SPARC (hosted under Solaris) and Palm compatible handhelds (native).
