Actually, there's a quick way to find out what video card is in your machine from the Windows command prompt.


First you need to get to a command prompt and run the 'debug' command. Now enter the following command at the '-' prompt (careful here!):


d C000:0010


Press <Enter>, and you should see the contents (in hex) of the start of your video BIOS. Press 'd' a few more times to get more information. For example, here's what I see on my Dell laptop:



-d C000:0010

    Oh how intuitive! I'm sure to remember that. Nuts to those cryptic Unix-like commands!
