I don't own a Cyberstorm PPC, so I can't help you with
that. Maybe you should start a new thread about this,
after all your amiga is working now.
BTW about the piv flashing, maybe you should just let it
be. If your flickerfixer settings don't need to be reset,
and if your not going to use a concierto or paloma etc.,
and if all is working well, the bootmenu isn't that
usefull. You know what they say: if it ain't broke, don't
fix it.
