One of our C2s still has a test firmware hidden in NVRAM. Because the firmware does not show up in "dir", I cannot delete it from the CLI. There was a KB article detailing the process of going into the Administrator menu at boot-up and choosing a hidden menu option to delete the file directly from the NVRAM. (I've followed it before with great success.) However, I cannot find the article now. I need to provide instructions to my local support to go clear the file out so we can upgrade it. Can someone please refresh me?
