Wait a minute! You may still qualify to install and play OFP.
Are you using Windows NT? Nope, sorry, can't help yah!
Do you have another graphics card, not listed as being supported? You might still qualify. For example, I originally had an S3 Savage IX 8MB chipset and OFP worked like a charm. How can you find out if your unlisted graphics card will work or not? Well, search the forums for the name of your graphics card or ask a question there. Also, try installing and playing the demo first. If it works, that's a promising sign that the full retail version will most likely work as well. Just remember to uninstall the demo before installing the full retail version afterwards.
