This ELF, In testing, no others worked

You must ensure that your NIC IP address you have your tftp/dhcp server on is 192.168.1.1 – bootloader bugs cause other IPs to fail on the TFTP Transfer

Once booted, DHCP will start broadcasting on eth2 and above, plugin and ssh to 192.168.1.1 or its IPv6 Address (ipv6 DNS server is good)

Switch the eth0 connection over to internet or push this image to it
