My CD-ROM doesn't seem to want to go into DMA mode. It's in PIO 4 and i tried changing it in windows but it wont change. I look in the BIOS and it says its in PIO 4 mode but there doesn't seem to be an option to change it. My motherboard is a Epox EP-8KTA3L+ and i'm running Windows XP. Does anyone know how i could possible fix this, it slows the whole system down when i use a CD and it runs really slow. It worked fine on my old computer so i don't think its the drive.
