Hi Steven,

Perhaps this could be of some basic sample/help, being based on 

_ if gpxelinux.0 is needed, it should probably be replaced by ipxe.
_ lpxelinux.0 (from official Syslinux archive) could optionally be 

_ from the Syslinux official archive, "efi32/efi/syslinux.efi" should 
be copied as:
    +-- pxelinux
        +-- bootia32.efi

_ from the Syslinux official archive, "efi64/efi/syslinux.efi" should 
be copied as:
    +-- pxelinux
        +-- bootx64.efi

The layout of the TFTP server being used is included in there too.
