FreeBSD/sparc64 Project


This page contains information about the FreeBSD port to Sun Microsystem's UltraSPARC® architecture. UltraSPARC is a Tier 1 architecture, and as such is fully supported by the FreeBSD project. However, the port is not as mature as the existing i386 or amd64 ports. Discussion of the UltraSPARC port takes place on the freebsd-sparc mailing list.
