Step 2 Power off the ASA, then power it on.
Step 3 During startup, press the Escape key when you are prompted to enter ROMMON mode.
Step 4 In ROMMOM mode, define the interface settings to the ASA, including the IP address, TFTP server
address, gateway address, software image file, and port, as follows:

rommon #2> SERVER=10.129.0.30
rommon #3> GATEWAY=10.132.44.1
rommon #4> IMAGE=f1/asa800-232-k8.bin
rommon #5> PORT=Ethernet0/0
