I understand that it is recommend for normal IDE drives, but what if I am using an Industrial grade CompactFlash card C:\ (as well as a non industrial grade one for my drive D:\?

Do I *still* need to enable DMA for these CF cards?

Thanks!

As long as the card supports it, activate DMA. Why wouldn't you?

Edit: To be clear, I don't think it's required for any drive to work, it just helps system performance a lot.

It will most likely not stay enabled after a reboot, since it doesn't seem to work with CF cards and 9x. Just try it. If it does not work or is not supported, it will fall back to PIO automatically.

I had to set the DMA mode manually in the bios to get mine to stay ticked. Win 98se and transcend industrial CF.

It works for me on my system (W98SE, i440BX, SanDisk Extreme). The DMA checkbox stays ticked and CPU utilisation during disk operations is lower.

I just ticked the box for both of my CF cards, rebooted, and they are still ticked! This is for both Win98SE, and Windows ME!

Thanks!
