Jared's NetBSD/xbox project page
Jared has setup
a page for his NetBSD-hacks on the Xbox.
(Please note that the Xbox port is actually a part of the
i386 port, I'm not aware of any changes to make it a separate port -
all that's specific to the platform is the kernel).
Jared's page includes the requirements for the port to run,
a list of what works and what needs more work,
where go get it, where to ask for support (port-i386@),
