How to enable DMA when using AMD EIDE controller??

[videotips]

How do I enable DMA for my ultra dma hard drives under Windows 98? I am using an AMD EIDE drivers. When I click on hard drive properties there is no click box for DMA.. Is it automatically enabled?

Yes that's normal for it to be greyed out or absent.

Run HDTach and see what your burst rates and CPU utilization scores are:

Yes. If your in DMA/66 mode, you have no option to disable DMA; It has to be enabled for it to work.
