I have scoured the mailing list and the web and I can't seem to find any
help on this issue. I am attempting to have EFI machines boot over PXE and
then load various Linux Live distributions. I have a similar setup over
standard BIOS machines and all is well on that end. First I have tried
SysLinux 6.0, 6.1, and 6.2 for various EFI enabled machines and thus far
6.1 gets me to the furthest point.

My clients successfully boot over PXE and grab the relevant files over TFTP
to get me to a simple selection menu. I have watched the interaction in the
TFTP logs and over tcpdump. All is well until I attempt to select a kernel
(Ubuntu 13.10 vmlinuz.efi). Regardless of where the kernel is located,
nested in a sub-directory of /tftpboot or not, the client always responds
with "File not found." It is odd since all other support files
(syslinux64.efi, pxelinux.cfg/default, vesamenu.c32, and so forth) have no

Any guidance or assistance is greatly appreciated.
