Video games should avoid ever trying to use virtual memory as it is far
too slow and will royally screw up gameplay. If you don't have enough
RAM to play the game, start unloading programs that are running in the
background to make room.
With 2GB RAM and 2 hard drives, my suggestion is to create a 2GB
pagefile on both hard drives. Set min and max to the same 2GB value to
reduce fragmentation of the pagefile.
