FreeBSD 5.4 sparc64 netboot install?

[Aaron Glenn]

All I've been able to find is installation instructions from 5.0 DP1
[1] and nothing for anything more modern. Is this method of
installation not support any longer? I've got a cd/floppy-less netra
that needs FreeBSD on it and I have no idea how to get it on there.

Please CC me as I am not subscribed to -questions.
