Bus Mastering & DMA
Posted: Sun Dec 22, 2002 12:39 pm
Hey Guys
Does anyone know of any devices other then Hard Drives and Floppies that is not ISA that uses DMA i don't think there is any. This means as long as Serial ATA uses Bus Mastering i will not need to support DMA in my operatying system. Also does Bus Mastering allow memory anywhere or does it need a block of linear memory like DMA (im guessing it does).
