Can anyone give me any tip?

I desactive firewall, all network interfaces except they use for that, I try diferents versions netinstall, with admin and without admin, 64bits and normal…

With linux version only I get “Unknown BOOTP architecture option flashboot from F4:xx:xx:xx:xx:xx (mac)

Thanks so much.
