[REQUEST] How to install silently/unattended w/pre-configuration?

I love this firewall and want to add it to my unattended WinXP install CD so that I don’t have to manually install and reconfigure everytime. Thank you in advance for any help you may be able to provide!!!

ok I found the script for backing up settings, so I can just apply the .reg file after installing… but I still need to know if there are switches to install silently/unattended. Thank you!
