The mysterious faulty DMA-chip in Atari STE has been matter of research from different sides. While many investigations resulted in the advice, to replace the DMA-chip by a "good" one, e.g. Czietz (chzsoft) has investigated into another direction and found that the problem may be solved in software instead. Further analysis of the different chips showed, that if the software driver part handles some edge cases differently, the chip works as it should!
Some nebulous guys picked up the theory and patched the famous and still developed HD driver by Dr. Uwe Seimet. The patch is not related to the product and to be used at own risk, obviously. However, if this proves to be true, we could see an end to the unfortunate "bad DMA-chip" tragedies resulting in massive data loss (talking straight from the horse's mouth).
The patch is accompanied by a lovely STE intro released at last Sommarhack.
