At times it will boot to the old OS. Please help : Mike

When it boots, whats the mac address of the interface? If its all zeros or all ones (ff:ff...) there is a deeper problem than it forgetting the IOS image. I've got a 2621XM that has that problem. The only solution I know involves having another one that works and an eprom programmer with the right adapter to reprogram one of the two chips thats socked.

This may sound stupid but when it boots I am not sure that you can see the MAC address. I get that there is a magic number problem then it goes to rommon mode. thanks mike

have you tried How to Download a Software Image to a Cisco 2600 via TFTP Using the tftpdnld ROMMON Command

That was it. I was using xmodem before and it wouldnt catch. This did. Thanks for the great advise
