But seems a "boot" code related problem: it happen before the kernel code
is loaded into memory by the stage 2 boot code.
I can only see on the monitor:
 "NetBSD/i386 ustarfs Primary Bootstrap" when I use the floppy;
or
 "NetBSD/i386 ffsv1 Primary Bootstrap" when I use HD boot;
then the pc reboots.

At this stage only the bootstrap code is loaded and running: not the
kernel. I think it is not related to kernel nor the way it is compiled.
Are you agree?
