Hey. I have been searching that one game since I've bought myself Windows XP and lost my ability to play DOS based games.
It's actually some sort of Car Driving game.
You saw the car from above and the road was always kinda S shaped. I think it's one of the newer DOS games because I can remember that it could play normal sounds and not the beeps from the PC.

Actually how it looked like when you played it.
I can remember some things like that you drove a red awesome car and your starting map was a city if I'm not wrong and in the second one you were in a volcano and you got attacked by fire birds.
I even still remember a cutscene and I think it's the one when you start a new game. The ground opens (and makes a ramp) while the car jumps out of the hole.
I gave up searching this two years ago after searching it for about three years.
Please help :o
