I'm studying for my CCNA and got an old 4700 router from my brother-in-law to practice on. While playing with the configuration setup I accidently changed my enable password since I can no longer get into the enable mode. I've been trying to use the procedures described in the Sybex CCNA Study Guide to recover a lost password. On page 524 it says to go into ROMMON by interrupting the boot cycle with a ctl-break. I do this and get the rommon>prompt. Then the book says to enter the o command and the configuration register will be displayed, but when I enter o at the rommon> prompt I get a message saying "monitor: command "o" not found". What am I doing wrong?
