I am not very familiar with computer specs terms but I would like to 5 box using Keyclone on an HP elitebook 8510w that runs Windows Vista Professional. I haven't bought any additional hardware so far so I only have 2 GB of RAM and I'm not too sure about the rest. Does anyone have suggestions? Would it be possible to 5 box on this or do I have to buy a desktop computer with a lot of RAM?
