It is an attempt to recreate the AmigaOS 3.1 such that it will run natively on a peecee, e.g. not as an emulation, but right on the hardware itself. quite a bit done, but needs much work to be complpete.
Actually, AROS is slowly being back ported to Amiga 68K and ported to PPC. Progress is very slow as only a single dev is working on both. There is even a dev showing interesting in porting AROS to ARM. AROS is open source and hence not tied to any given arch. x86 is the primary developement arch for many years, though.
