On behalf of FreeBSD/MIPS team I'm proud to announce that
project has reached single-user stage. On the moment FreeBSD/MIPS
runs only in malta board emulation mode of GXemul though adm5120
support is on it's way and people with real MIPS-based hardware
can start playing with latest repo snapshot bringing FreeBSD on it.
Many thanks to all who contributed with their time, efforts and
experience. Especially to #bsdmips crowd for patience to newbies :)
Attached mips.txt is a "recording" of sample GXemul session.
Current p4 repo snapshot: http://kanar.ci0.org/mips2.tar.gz
Check http://wiki.freebsd.org/FreeBSD/mips for sample build script
