To recover from a lost "enable password" use the BREAK function on the console to interrupt the boot. Change the boot register to force the system to boot from ROM. Reload the system. Go into enable mode, open a log file on your terminal program and do a "show config." Review the log file, if the password starts with a 7, run it through a cracker and recover it! Change the register back to boot from flash and reload.
Otherwise, you can change the enable password and write it to memory (which wipes out all but the most basic IP stuff). Change the boot register to boot from flash. Reload. In the captured copy of your config make the corrections necessary (i.e., put the new enable password in, fix the delimiters around your banners, add the no shutdown to your interfaces, etc.). Reload the orginal configuration to the router.
This should work fine for the 25xx series, at least to the best of my recollection 8-]

That will blow-away the current config as well, so you will
need to start again with the config.
