I have a 4240 that I hav eno password for and I am struggling reset it. I have followed the Cisco ROMMON Here is the instructions
Step 1 
Reboot the appliance.
Step 2 To interrupt the boot process, press ESC or Control-R (terminal server) or send a BREAK command (direct connection).
The boot code either pauses for 10 seconds or displays something similar to one of the following:
•Evaluating boot options
•Use BREAK or ESC to interrupt boot
Step 3 Enter the following commands to reset the password.
confreg 0x7
boot
OK after booting I get a screen with two options
1-IPS
2- IPS Recover
I choose #2 and it boots to BusyBox. NOw I am in a Linux prompt, what is next I can't find any info. THe End Game is to get the pass reset and restore the 4240 to default to use for the my cert study. Any help would be greatly appreciated.
Use BREAK or ESC to interrupt boot.
Use SPACE to begin boot immediately.
Boot interrupted.
