DMA mem-to-mem doesn't work on modern computers. To see if yourcomputer does support it, go to my webpage, listedbelow, go to the Turbo Pascal, section and download thefile called "Lot's o source" inside that is a programstraight from a hardware book on the DMA chip, which willtest if your supports DMA. As it is, with modern comps, DMA is slower than usual methods,and messes with multi-tasking as it denies the CPU access to memoryfor the duration.
