Load a new Cisco PIX software image from a TFTP server

If you don't already have a TFTP server to use I recommend using Solarwinds Free TFTP Server.

1. Copy bin file to TFTP Server
2. Configure Ethernet Interface on the firewall so you can connect to the TFTP Server (test by pinging the server)
3. copy tftp://192.168.100.25/filename.bin flash
4. Restart firewall using 'reload' command
