Hi: I know this is an older router but I am using in my lab for testing purpose.
Origianally I had a problem upgrading the IOS image because I received message from the router saying the system flash not writable. So I found the article describing what to do to make the falsh writable: (the articale basically instructed me to use a configure-register 0x2102, it went on to say that after I reboot without saving the flash should be put back to the read-only mode) Well I followed the instructions but I could not copy the new IOS image from my TFTP server to the router, because it kept telling me that no protoco available. So i use the following command (no configure-register 0x2102). Now all I have is a > sign and none of the normal IOS command lines are working. Anybody with any idea how to fix this? I appreciate your help in advance.
