Hey everyone, I just got my 98 build up and running and everything runs great. I wanted to increase performance by enabling DMA for the IDE to CF adapter I have as well as the optical drive. My MB is an Intel D815EEA2. When I go into device manager and right click to see if there are any options, there are none. Also I know the drive is stated as IDE removable but I didn't know if there was a way to make it act as a regular connected drive so I can then enable DMA perhaps? This is also a problem because the trash can doesn't really work as it acts as a removal device so anything deleted is permanent and doesn't go to the trash. I will also link a picture below of the adapter I got as I am not sure if it even supports DMA. I have 80-wire ide cables as well as the Intel Application Accelerator program. If anyone knows any info on this that would be great as I am trying to follow PhilsComputerLab's DMA tutorial. Thanks.

There is an application that comes with the Intel Application Accelerator program that should allow you to check the DMA or PIO mode that you are running at and also change it (within the constraints that the hardware allows) .
See https://translate.google.com/translate?sl=aut … ion-accelerator

The removable aspect is probably due to the CF card having its removable bit set and Intel Application Accelerator detecting that . AFAIK, this is only an issue with newer operating systems, such as XP, not Windows 9x and earlier, but Intel Application Accelerator might be sensitive to that .

Happy to help and best of luck . Please, let us know how things turn out .

By the way, if your CF to IDE adapter turns out being suspect on the DMA, this https://www.startech.com/en-us/hdd/ide2cf definitely works in DMA mode (I have one).

Oh, and I should mention that my experiences with Intel Application Accelerator were not that great on an 815EP/ICH2 motherboard . I have better results with the patched ESDI_506.PDR in BHDD31.ZIP (the patch is only really necessary for drives/CF cards bigger than 127GB) from http://www.mdgx.com/add.htm#BHD .

As I strongly suspect that the sensitivity to the removable bit on the CF card is an Intel Application Accelerator "feature", you may find that you are better off with the native ESDI_506.PDR driver (or the patched one if drive size warrants it) .

Asides from the fact that Intel Application Accelerator supports drives bigger than 127GB without the need for any patching, I have not found it to be particularly useful .

Nice! Thank you for the info, this sums up a lot for me. I will try the adapter you linked if DMA doesn't function with the adapter 😀

Oh also using the program I got some info here to show. I have no idea sadly what DMA SW mode is and if I really need it but is there such a thing as DMA supported optical drives? Drive is a Toshiba SD-M1202. On the bright side it shows that the CF card has it and through BIOS seems to be enabled. So I should be good on that end as the reason why device manager didn't show the DMA option as I think it's already enabled to my better understanding. Also I noticed that the optical is PIO and the CF card is UDMA, I do not know the difference between them. That was pretty much the rest of my question as I just saw the results from the Intel program and got curious. Thanks, pictures are posted below 😀

DMA SW = DMA single word
DMA MW = DMA multi word
UDMA = Ultra DMA

See https://en.wikipedia.org/wiki/Parallel_ATA#Sp … _transfer_modes

As for optical drives, DMA is typically supported and can be enabled when not automatically enabled (DMA being enabled is pretty much mandatory if you want to play a video DVD in DVD-ROM drive on a PC) .

You should be able to try to enable DMA mode for your optical drive using the Intel Application accelerator application .
