How To Enable DMA For Windows XP
For Windows XP, Direct Memory Access is not set for individual Hard Drives
and CD Rom Drives as depicted above. Instead, DMA is set for the Primary
IDE Channel and the Secondary IDE Channel. In short, each Channel allows us
to have two devices connected for a total of four devices. These devices
can be a combination of Hard Disk Drives, CD Rom Drives, CDRW Drives, DVD
Drives and Tape Backup Drives etc. Therefore, if both channels are set for
DMA access, then all the devices in your system will be set to use DMA.
