with regards to the driver installation it depends on how it came.
Some drivers all you have to do is double click the download and it'll basically do the rest for you.
Some you have to decompress first (using a utility such as winzip
www.winzip.com) and then do the above or the below:
Some you have to right click a file with a notepad icon and then select install.
Finally, and the most complicated way is that depending on your version of windows you have to go to the device manager (basically right-click My computer then go hardware. In Win XP/2000/NT then slect device manager. 98/95/ME ought to be there). find the device you wish to upgrade the drivers for and then double click on it (here it would be under display adapters). Having done that go to driver tab then update driver. Hit next (if available) then slect allow it to search for the driver. Tick 'specify a location' (this bit may be relevant to only Win 2k.....its the only version I have at hand) then next. A popup comes up and you hit browse. Find the driver and hit ok. It ought to list the driver in a box (I think) and then you hit next. It installs it then you restart the machine.............you may need to reset resolutions and stuff after restarting.
This is roughly correct, as I say it depends on your version of Windows (assuming you are running windows) and how they have given you the driver.
