You have to configure /etc/dhcp/dhcpd.conf to avoid this. Something like this could work:

        if exists ipxe.efi {
                filename "pxelinux.0";
        } else {
                filename "some other NBP here";

Please try to read http://ipxe.org/howto/dhcpd
and have a scan through http://ipxe.org/docs

We do not know what "properly" means for your situation.
