Actually, it should be d:\. When the game gets to that point, it tells it to load the stuff from the game Data Files, which happens to reside on the F:\ drive. I know it logically doesn't make much sense, but if you put F:\ there, you'll have to include the path info somehow (not sure if that's really possible) because when it reads D:\, it look sin the game directory and needs to find Data Files at the root of that directory. Since it you want pointing it to F:\, you'll probably need to find out if the XBE has a checksum, and how to calculate it.
