I have an ATA hard disk and a DVD drive both sharing an ATA/UDMA IDE slot on my motherboard in windows 98. The problem is, when they both share the slot, my DVD drive is DMA enabled and my hard drive isn't. If I move my DVD drive to the second IDE slot then both are DMA enabled, but the DVD playback suffers and is very jerky and unwatchable. I need my hard disk DMA enabled as I use it to record music and I am suffering from slow writing to the disk.
Please help - I have tried everything and am getting pretty fed up with it all!!
