I have a cisco 3925 router that has come in from a customer with no flash cards installed,
I copied an Image from my pc to a Verbatim 256 MB flash card and installed c3900e-universalk9-mz.SPA.151-4.M4
upon booting the router in rommon mode I issued the command boot flash:c3900e-universalk9-mz.SPA.151-4.M4
rommom tried to boot from the flash card but I keep getting the error "loadprog error not an executable ELF file"
can I please get some help as to why this happening.
