By the way, DR. Molloy seems to be a good guy, and has a lot of useful information. But much of that information is dated, and wont work with current images. What this boils down to is that if you're not an expert, or at least proficient with Linux. You're very likely to run into many problems. It may be best just to pose your questions here on the groups. Robert knows all the details of the images, and often times I can at least help pick up his slack. As well as I probably have a lot of hands on experience with most of the peripheral modules, on current Linux image.
