I followed this and I could boot syslinux.efi through a EFI shell on 
several real EFI machines. I got no boot picture either (I was using our 
config which uses gfxboot menu), but I got a boot: prompt which I could 
use to boot various entries without problems. Successfully tested were 
HP Pro 3400MT, Compaq CQ2903EG and a Lenovo Notebook which I forgot to 
write down the exact model before giving it back...

It did *not* however work with a MacBook Pro 15" 11th Generation with 
Retina Display. UEFI Shell (from EDK 1.06) boots, but when I try to 
start syslinux.efi, the machine just gets stuck after pressing enter and 
does not respond to anything but pressing the power button. Maybe 
someone likes to look into this, I'd be glad to help. Grub-EFI boots 
just fine on this machine.

Bye,
Andreas
