skip dhcp with ipxerom possible?

[NiKiZe]

As I said, you need to get IP config in some way, if you are burning ipxe, then the options are dhcp, or set by script

The picture does not show ipxe, but the original boot ROM, disable the ROM to not get the prompt, or put it later in boot order.

You could test by putting ipxe on a USB, with embedded script - and you should do so anyway before burning...

Now remember that onboard NICs don't have their own ROMs, so you need a real card to flash it.
