The latest issue of Micro Cornucopia (Sept/Oct 1987) contains an article
titled "DMA Control on the PC". The article goes into considerable
detail on theory use and abuse of the 8237 DMA controller as it is used
in the PC. You can call Micro C at (503)-382-5060 if you can't find the
magazine locally.
