I'm trying to install NetBSD on a Performa 6360. I created the disk with
boot.fs image as described in the Install Manual (dd if=boot.fs
of=/dev/fd0 bs=36k; fd0 because image was created in a GNU/Linux system).

So, when I try to boot (boot fd in OF), the disk simply ejects.

What's wrong? I don't believe in disk problem, because I created this disk
twice, and failed twice.

Thanks for any help.
