I'm not sure I'm down with the fat32 cf card concept though I can see where it could be useful. What I want to do is have a minimal functionality netbootable image that is sufficient to set up network interfaces and then do: ftp> get pfsense.img "| dd of=/dev/ad0" and completely blow away what's on the flash and replace it with something new (even via serial console over a networked console server from my desk, without getting up and going to my lab where I have a small herd of these puppies as packet pushers), but particularly without having to break out a screwdriver and a nut driver and pull four sheet metal screws, four machine screws, and two rs232 retaining screw standoffs. There is pxe in the bios on the ALIX... perhaps you know of something that's already pxebootable that will do this? ---rob
