So I managed to install Debian 5 on an eBox 3300MX (an embedded type computer). I added a custom kernel after getting a basic install done. That was to get the network card to work. After that, I finished with installing, since I was doing a net install, and it worked fine. However, since then, I am unable to get the Debian to use the network card again. The only thing I can think of is that the Kernel updated during the install. I tried booting into the previous working kernel, and that did not work either. I get the error No network devices found.However, I can open Network Tools and view devices, and I see the network card, with its MAC address and other info. I have it listed in etc/network/interfaces as auto. Thus, I don't understand why it does not want to work.  I'm not really sure what other info is relevant, so please comment and let me know.

It turns out that during the first update I did (apt-get install ntp), that ifupdown was removed. Since I did not immediately reboot, I was able to continue with the net install following this. I discovered this by completely installing Debian again, and carefully looking through the operations during that update (well, and the help of someone who knows much more about Linux than I do). Anyways, all it took to get going again was apt-get install ifupdown and now everything is good.
