I was wondering if anyone knows how to foce DMA mode by editing the registry. I have a Pioneer 114 DVD drive, but it does not automaticaly support DMA mode (unless one of the 2 reserved jumpers support that). I have tried the disabling DMA in the BIOS (I have the Abit KA7 MB BTW), but I still get PIO mode only. One time, when Win2k first came out, I found a post telling about editing the registry to force DMA to be enabled and it worked, but I lost the message a long time ago. I have installed VIAs bus master drivers, but then my Memorex CRW-1622 CD-RW (PIO mode only, because it's a 2x2x6) disappears and the Pioneer drive won't play DVDs. I have tried editing a few registry settings, but Win2k restores them when it starts again. Thanks, Richard richough3@hotmail.com

Well, thanks for the suggestion, but it still didn't work. I did find a solution though. I installed the VIA 4.28 drivers, but I edited the Win2k IDE Inf file so it would not enable DMA on the IDE chain my CD-RW was on and it finally showed up with the VIA Busmaster drivers installed. I was actually surprised it worked, but with VIA's busmaster drivers, although it enabled DMA on my Pioneer DVD drive, WinDVD won't play, although PowerDVD works fine.
