Debian squeeze image from here http://www.raspberrypi.org/downloads download the zip file and extract it. You will end up with a .img file this is the operationf system that you are going to build onto the sd card. Once you have done all that pop the sd card into the pi and power up. MAKE SURE THE PI IS ON A NON CONDICTIVE SURFACE OR BETTER STILL BUY AA CASE. Look on eBay. The first time the system boots it may take a while but have faith. It needs to configure itself. If you are going to buy a SD card for the job go got a class 10 card. I find they run reasonably well. Another thing you will notice is a total and utter lack of sound. This is because the drivers are still in testing so are disabled. Not to worry the web is your friend Without starting the graphical interface and assuming you have logged in a pi, type the two following commands. sudo apt-get install alsa-utils This will download and install the drivers. "Sudo" allows you to run the command as a super user "apt-get" tells the operating system to get the application from the "app store". "Install" tells the operation system you want to install the app and "alsa-utils" is the app. Google apt-get for more info. Once that has installed and you're back at your command prompt type sudo modprobe snd_bcm2835 This tells the operating system to load the audio drivers. NOTE TO LINUX GEEKS!!
