Possible DMA problems, please help

OK, I got a new cdrw drive, its a liteon 40x12x48. Here's the problem, my computer gets extremely slow when I'm working with the drive, I've checked out my cpu utilization and it is steady 100% when copying files from or writing cds. Computer is pretty much completely unusable when doing anything that involves a cdrom, even the video is slow to update with a geforce4 ti4600. I suspect that DMA is not being enabled, but since I've installed Intel application accelerator(their hard drive controller drivers) it has removed the DMA check boxes from my drives. I'm running windows 98 with a Pentium 4 1.6 Ghz @ 2.6 Ghz with the pci bus locked at 33.3 mhz. It's not overclocking because my computer is rock solid stable and I've tried running at default speed with no success. Perhaps someone knows of a program that can verify if dma is enabled or disabled?
 
The DMA check box being greyed out is correct after installing the
Intel application accelerator. It has no effect on the settings.

You need to adjust the settings through the Diagnostic Utility.

To make sure you have it installed properly:

Click Start\Settings\Control Panel\System\Device Manager
tab -> Select 'View devices by connection.'
expand the 'Plug and Play BIOS' listing
expand the 'PCI bus' listing

Intel Hard Disk Controller driver listed indicates it is using the update.

How do you have the CD-Rom and drives set?
(Ide channel, Master, Slave etc..)
