   Anything else from a router standpoint is a crapshoot for supporting Dnsmasq options or proprietary PXE boot options, check Google for support (try your exact router model number with 'pxe boot') or look into setting up your own DHCP server in Linux.
   
   This image also contains `netboot.xyz.efi` which can be used to boot using UEFI network boot. The UEFI boot and menu will have limited functionality if you choose to use it.
