     Is there a way to use DMA to transfer a 64k block of memory to
     another location? 

     At one time I heard it wasn't possible.
     At one time I heard it was possible.
     At one time they said it was possible, but most PC manufacturers
     don't include the proper wires on the motherboard to do it.
     I have seen code to do it, but I never got it to work.

     Has anyone done this for sure, not just speculation?

     Thanks
