About NetBSD/arc

NetBSD/arc is a port of NetBSD to the MIPS processor based computers which comply wih the Advanced RISC Computing (ARC) specification put together by the Advanced Computing Environment (ACE) Consortium in the early 1990's, as an alternative to Intel-based PC's.

This port originally started as NetBSD/pica port made by Per Fogelström, and supersedes it. This port is also based on efforts done in OpenBSD/arc.

Earlier pre-ARC MIPS machines are supported by the NetBSD/mipsco port.

The portmaster is collecting detailed information on as many ARC implementation variations as possible. An explanation of how to get internal details using Windows NT is available.
