Force DMA mode for CD-RW in Win2k?

I have a CD-RW that worked great in Win98SE using DMA mode. The burner hardly used up any CPU time when burning, and I could do a bunch of other things at the same time.

Win2K, on the other hand, doesn't seem to want to run it in DMA mode. When I'm using the burner, CPU usage is much, much higher than in Win98SE with DMA on, and forget multi-tasking when burning.

I've set the controller to "DMA if available", but Win2k still runs it in PIO mode.
Any way to force Win2k to run the drive in DMA mode?
I know the drive is capable of it, being that the instruciton manual for the drive says to use DMA mode, and I've run it under DMA mode in Win98SE with good results.

try uninstalling the ide channel that the cdrw isa on in device manager then reboot.
windows will redetect the channel & reinstall it hopefully using dma for your drive! :)

You might want to try installing an ASPI Layer.. search google for ForceASPI I think the last and final version was 1.7, download that, and then install it.

If not that, check that you have your IDE channels properly setup in BIOS to use DMA
