Hi

You first need to backup the IOS from the working router.Then you can copy that IOS to that non functioning router.

As there are two most popular ways to so that :

Network based (TFTP,FTP etc) ---fast

COM serial based :Xmodem --- slow

You can download free TFTP servers like solarwinds and 3Cdaemon.

You can view the link given by other poster for the procedures.

JD
