First and foremost: version numbers and build sources (ie precompiled
binaries from the official archive file)?  EFI32 or EFI64?

How are you setting the value for the clients?  Tried a packet capture
on your DHCP server and TFTP server?  What kind(s) of message(s) do
you see?  Tried to go simple and load syslinux.efi and use the TFTP
capabilities of your uEFI environment?

Did you happen to hand-build lpxelinux.efi?
