Video Buffer is not being cleared on Startup

I've found a few threads that talk about this, but none of them have come up with a solution. Basically what is happening is that when you run your game the contents of the video buffer is being displayed to the screen while the engine is loading. This often looks like garbled images and colors. Is there a way to clear the contents of the video buffer on startup through script? Or do you have dig into the source code?

Thanks for the help!
