Check DMA for cd/dvd drives?

[DashK]

My DVD drive set to UDMA 2 in the motherboard bios, my question is do I need to check "Enable DMA" in the drive proprties in Windows? The OS in question is 98SE.

Thanks for any help.

I would definately "check" the DMA, Windows 98 SE defaultly has them disabled on Non-SCSI & RAID controllers.
Enable DMA and see what happens, I doubt you'll notice any performance gain anyway, CDRW & CD & DVD drives don't even push the evelope of performance speeds of UDMA 33.

I'd personally disable DMA for my DVD drive, but i did that to make it work....about a month ago i wondered why my brothers computer went so much faster than mine...turns out he had DMA on and i didn't.....so i turned it all on, and my drive speed jumped by 8x easy....but i couldn't access my dvd's.....so i had to turn off DMA for that drive, and after that it worked like a charm...
