|Yes you can dump Audrey's internal flash to an image on a CF card, and then restore that image back. Do it all the time. The problem is that a CF backup is just a copy of Audrey's flash, and we know how to do that. What we don't know how to do is to make an image on CF from scratch that is compatible with Audrey. Even the very first CF image by Sowbug was just a hacked up version of a known good image. This is further complicated by the fact that installing a different OS would probably mean changing Audrey's boot loader code, and if you get that part wrong, then you have a permanently dead Audrey.|
Whatever "image" you might find for a different OS or different hardware won't be compatible with Audrey. Unless or until someone can convince 3com to release detailed specs on how all this works, I doubt there's much chance of success.
