Bus Mastering & DMA

[pskyboy]

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).

sound cards use DMA

Surely thats only the older ones and ones supporting soundblaster 16 which will be irrelevant to me.
