So looking into chipsets that support DDMA but that don't work in practice at least on some motherboards, I am thinking that DDMA is not being enabled by the BIOS.
This looks to be a possible issue with some VIA chipset based motherboards at least. I have not looked into other chipsets yet.
I'm going to see if I can make a utility that will change the register settings to enable DDMA on these chipsets when they don't work by default.
I wonder if PCISet or WPCREDT/WPCRSET would be able to do this.... going to test and see if it does. If it does, then that would make it that much easier to make a stand-alone utility just for this purpose.
