I never tried that version myself...1.4b does not work either. regardless of whether dvdelf.bin and boot.elf are provided or not.
I used an earlier version of FMCB to boot uLE, and then launched the FMCB v1.5 installer from uLE.installation was attempted via swapmagic disk.
Are you sure that the guy at the other end is doing what you tell him correctly ? The majority of all complaints boil down to user errors in the end...strange. i've tried to help remotely, i don't have physical access to the console.
