This problem of the unsupported card plagued me for months. In a moment of sheer desperation, I managed to fix the problem.

Step 1: Right click on MOH Airborne in your steam library and select Properties.

Step 2: Click Launch options under the General Tab, and enter these letters. xadapterd10

Step 3: Click ok, and launch the game. Then hit Control Alt + Delete and open the Task manager.

Step 4: A box will pop up stating "The map specified on the commandline 'xadapterd10' could not be found. Would you like to load the default map instead?" Hit Ok, and click back into MOH.

I've recieved a lot of feedback due to this guide, and I'm glad to see that it works for many of you. One recurring concern, however, is the graphics in game. It appears that, for a few of you, guns, npcs, and other textures are blacked out or simply non existent. I'm sorry to report that I don't have a way to fix this issue. It is simply a side effect of running the game on an unsupported card. This problem only occurs for a few of you folks, so if you want to try this solution, note that you won't necessarily develop the same issue.
