I have asus maximus, WD HDD and i'm trying to get the best dma mode for my set up, but seem to be stuck at dma mode 2. My cd/dvd is dma 5 in device manager but HDD is 2 Do I have to load a driver prior to operating system (jmicron?) to ensure i can utilise dma 5/6? In my bios i do not get any options to select dma mode, I am in acpi mode rather than IDE. This is my first build and would appreciate any help, thanks.
