How To Make A Media Server By Chris Colegate
To Start Set Up The Pi
The first thing you need to do when you get your Raspberry Pi is to format and install your chosen OS onto an SD card. I use Boot Berry because it is easier to install (drag and drop the files) and because I can have Raspbian and XBMC installed without having to swap out the SD card. Once you have you have the OS on your SD card connect your raspberry pi to a display with the HDMI or the RAC port, then plug a keyboard and mouse in or a usb hub if you want a wifi dongle too. If you want to connect your pi to the web (Radio, Netflix) you will need a wifi dongle or an Ethernet connection.
Now connect your power with the micro USB (See picture)
the first time XBMC boots up it will take a while creating all the start up files. Once the start up is complete plug in any USB drives (they will appear in with your with your /media/usb )with your media on and use the pi as you wish! play about with setting and plugins. Once booted up the gui should look like this:
