Hello, I have a 2500 router that always starts with this prompt: routername(boot)> altough the register configuration setting is 0x2102. I noticed that the ios image on flash has an invalid checksum, so I tried to get a "new" one via tftp, but once the download has completed, it calculates the new checksum and it is invalid again! Supposing it's a memory issue, I tried replacing the flash memory with another from an identical router with the same ios image: this time the checksum is valid but the prompt is still the same!!
Could you help or show the right way to solve this problem? Thanks in advance.
Bye.
