If you grab yourself a copy of the latest QEMU 2.6, you should be able to happily install FreeBSD-current under qemu-system-sparc64 in -nographic mode. The emulation is still a work-in-progress but one of its primary use cases is allow people to generate builds even if they don't have access to the real hardware. ATB, Mark.home | help
