I bought a used Cisco 2501 router.
I need to wipe out the old data because the old user login is still on the router and I can't jget in to do anything. if i replace the old ROM chips will this give me a clean config?
Or could i just remove and replace the original ROM.
Note: forget about doing a password recovery, the break bit is set to "disable".

I believe you will need to replace the ROM or "flash" memory in order to get a clean config. The router boots to flash on power-up, so just removing and replacing it won't do the trick. That would clear the NVRAM. Just out of curiosity, have you looked through Cisco for info on the break bit being set to disable? I thought at one time this was an actual hardware switch or jumper on the machine. Best wishes,
