usually when you are in the bios of the computer, the page where you can change the time and date has also the list of the drives, primary master and slave, secondary master and slave floppy ecc... On mine, it is set on auto, but if I select for example secondary master and press enter, it goes into another window where it shows the drives name, pio modes and dma modes, that is the place where you could have the dma off by default


how do you know that the dma is off? what are you using to detect it?
