I just realized another thing: Do to the way that these cards are designed, I think there might be a requirement that the shared memory address be on 16K boundry - so you should use 0xc8000, 0xcc000, 0xd0000, 0xd4000, 0xd8000, or 0xdc000. On some motherboards you might also be able to use addresses in the 0xe0000-0xec000 range, but this often does't work. -DG
