|Question one, if you are installing Windows XP Professional in the Virtual Machine, the existing drives are shared with the visual machine automatically. You need to read the instructions for the MS Virtual Machine for Windows if that is what you are using.|
Question Two If it ant broke don't fix it,
In the Intel i3, i5, ,i7 CPU;s the Graphics is integrated into t the chip and in the case eif the i5 it is called Intel graphic HD3000 In the Inspiration range of laptops the integral graphics are disabled and it uses the second one, the Nvidia Geforce 525M. So you only need to install drivers for that which you will find on the CD that came with the laptop or can be downloaded from Dell.
You can still use two monitors though, the internal monitor and an external one with an extended desktop but they will both be using the Nvidea.
