This procedure requires that you know what version of software is currently on your firewall. Once you know what version you have installed, you will need to download (from Cisco.com) the npxx.bin file required for your version of software. For example: np63.bin will work for any that has PIX version 6.3x software installed. If you have 5.1 you will need np51.bin and so forth.
You will also need a TFTP server from which to download the npxx.bin file.
