First, NO, you can’t do HD without the DNx board. As for the P2 workflow there are several. Here are two, you can import the footage directly from the camera, or put the footage on a seperate hard drive(a good idea) when you open the folder named content you will see five folders, Two of them are called ‘Audio’ and ‘Video’. Copy the contents of these two folders to you Avid MediaFiles/mxf/1 folder on your root capture drive. when you restart Avid create a new project, avid will scan the new media and you import it to your bin.
