Help Cisco 1841 config?

I will take it off your hands, I know how to use it :). To work with this router, you really have to have a pretty hefty Cisco IOS knowledge set. There are literally thousands of commands with different syntax. What are you trying to actually do with it? To get past the pword you need to reset the register. Boot up the router, before complete book up, send a break command, from there type confreg 0x2142, then type reset. When it restarts, you should get a prompt. From there, just type no to all the questions. When you get to the CLI, type enable and type write erase and this will reset the config to factory. Then reset once again and you might need to change the register back. You can check it when it reloads by typing show run and check the register number, it should be 0x2102. If it isn't, just do the confreg 0x2102 command.
