I just got a 2951 router the other day that came with a 4GB flash card. I can copy to and from the card, but I can't seem to set the system to boot from it. Everytime I issue the command "boot config flash0:/startup-config" in the from the global configuration prompt I get a response that says "File System Flash0: is unavailable. I formated the card and tried again and got the same response. I spent most of the day yesterday googling for anything, but can't seem to find any documentation on that response. Has anyone else seen this before?
