 Indeed, thanks for pointing it out -- I use ELF over MOP and keep 
forgetting about people preferring TFTP, sigh.  I wonder whether `objcopy' 
might be doing a better job than `elf2ecoff' these days though.  It may be 
worth checking...

 It all boils down to padding out what cannot be expressed in a less 
capable format after all.  That's what I did in `mopd' for ELF support too 
-- holes between segments are transmitted as zeroes.  Though MOP clients 
may actually support discontiguous images as each MOP "downline load" 
packet has its designated memory load address included in the header (it 
just shows how reasonable a bootstrap protocol it is!).
