Hello, I'm Enrico an italian student. I have a problem with NetBSD. I'm
installing on a Macintosh PowerBook 520; the first step (build filesystem)
is ok and also the second step (load files) have no problem. When I try to
boot the system the booting sequence halt after this two lines:

root device: sd0
root on sd0a dumps on sd0b

the messages before that moment (when the machine halt) is correct and there
is no error or wrong information. Can you help me?
