How to clear an ASA`s configuration
====================================

1. Reboot the device

2. On boot hit `escape` so that you break the normal startup process and enter 
   ROMMON. 

3. Change the current confreg so that you can bypass the current startup config 
   sing the command:

	rommon #1>confreg 0x41

4. Reset the appliance with the boot command, 

	rommon #2>boot

5. You will then be presented with the ScreenOS CLI and the ASA having a completely clear config. Run the commands :

	ciscoasa > en [when asked for password just press enter]
	ciscoasa # conf t 
	ciscoasa (config)# config-register 0x01 
	ciscoasa (config)# copy run start
	ciscoasa (config)# reload
