I am trying to help my daughter install Zoo Tycoon 2. She has a Compaq 2190US (Laptop) appx 1 year old. I just installed more memory so it's maxed out at 512, but only shows 448. When we try to install the game, we are told that it cannot run with her graphics card, which is listed as: ATI 1GP 340M. I'm not sure where to go with this. I was told that the computer has shared memory, because it only shows 448 mg RAM, not the 512, and that I could change the BIOS and make the game work. First, I have no clue how to do this, and second, is this correct information, or is there more I need to do first? I am a mac user so PC's are a bit Greek to me - I'm a quick learner but need some direction!
