Hi Steven,

Perhaps this could be of some basic sample/help, being based on 
Debian:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=720589

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

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

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

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

Regards,
Ady.
