You misunderstand. Will is suggesting that someone format a CF card in a 
sup720, put the CF card into a unix box, "dd" the physical disk image 
off, and transfer it via the net (as opposed to awkward physical means) 
to the OP, who can then "dd" it back on and put the CF card into the sup.

While we're on the subject, if anyone from Cisco is paying attention - 
your stupid shenanigans with slightly non-FAT filesystems and hidden 
areas are EXTREMELY IRRITATING and actively detrimental to the ability 
to recover a broken box.

That's sound advice, right up until the point cisco make the base image 
 >64Mb (which may of course never happen). Sadly it does not help the OP.
