How to speed up your cd ROM data transfer?

Most of CD-ROM devices support DMA, but Windows XP puts them in PIO (slower than DMA). DMA wont speed device, but it will use less RAM memory, and that way data transfer from CD-ROM to computer will be faster.
..... Steps to enable the DMA mood:-

First go to My Computer-Hardware-Device Manager. And Find "IDE ATA/ATAPI Controllers" and click? +? (Plus) near it. Double click on? Primary IDE channel? Look at? Advance settings? And look at Device 1 setting. It's probably set up to PIO transfer mode. Set to? DMA if available?
Back to "IDE ATA/ATAPI Controllers". Do the same for ?Secondary IDE channels? Now If it's in PIO mode.
If this won't help, you can reinstall IDE channels that won't accept DMA mode. And that you can do in following way:
Right click on IDE channel, ?uninstall? And OK.
Restart your computer and look if IDE channel accepted DMA mode.
IN some cases, you can get only Multiword, but that's better than PIO mode, too.
