Hi! Well, you want to put your windows XP on the first boot position. That is not a problem. In the process when you start your pc, you have to choose windows. Then select XP and press + button on your keyboard. That will set XP windows on the firs boot place. I hope that I helped you.
Hi! Well, that is ok if you use a 4x AGP. I don’t know which motherboard you have? But I suggest that is not a problem. If you want to have better performances, you need to buy better video card. For now just upgrade it with the freshest driver. It will serve god some period. Then you will need to change it, if you like to play required games.
