I've just started playing with pfSense, as it looks like 2.0 will solve every issue I've ever had with Endian.

That being said, I thought I'd give it a try on the home-brew firewall appliances we've been deploying. They're ATOM-based.
From what I was able to tell, it looked like the CD iso is what you use to install on a fresh drive, so I downloaded the one from Feb 16th and gave it a shot. It wouldn't boot (see attached pic). Indicates we have invalid mount options, and asks me to modify Loader variables....
Thoughts?
