Hello Netpros.
Whilst attempting to perform a standard enable password recovery on an 803 router, I discovered that a ROMMON password had been set. This had the significant disadvantage in that I could not set the config register to bypass the configuration on startup using the set command.
I've browsed Google and this site and there seems to be some reference to a cookie and/or priv command that may assist with resetting a ROMMON password but this particular router does not seem to understand either of these commands whilst in disable mode.
Excerpt follows:

Hi Adrian, what you need to do is;
boot> enable debug
password: em gubed
boot> [DANGER] passwd
new:
again:
boot> [DANGER] enable
boot#
boot#save
boot#

Hi,
Yes, if you get this boot prompt with the ">" and not "#" that means some joker set a ROMMON password without reading the documentation what is the impact of that (and not documenting it as well). You have to contact Cisco TAC to clear that password, it's not written in any documentation how to clear it.
Regards,
Dandy
