We provide openbios-sparc64 ROM image which can be used standalone for
quick tests. Then CD boot from various distro images (Linux, HelenOS,
OpenSolaris) can be tested, loading works (except for OpenSolaris) but
the kernels does not get very far. Also, Sparc32 Linux user software
can be tested with sparc32plus emulator, this tests the compatibility
mode of the CPU but not 64 bit features. I'm using the above in my
test setup.

In addition, OpenBSD/Sparc64 userland is fully 64 bits and V9, so
bsd-user can test the 64 bit CPU features. This part is not finished
yet. Booting from BSD CD images does not work.
