Due to popular  request, I uploaded a binary distribution  of the
NetBSD-current bootblock to ftp.uni-regensburg.de
pub/NetBSD-Amiga/incoming.

You'll have to mark your root partition  bootable from AmigaOS with
HDTOOLBOX or a similar program.

Read the man page very carefully, before you installboot; else you
will probably destroy your RDB and partition table, making your
system unusable.
