Which direct memory access channel is used for the floppy controller?
From http://www.brainbell.com/tutors/A+/Hardware/Direct_Memory_Access_DMA.htm "DMA channels use the same rules as IRQs. Just as with the 8259 chip, DMA availability soon became a problem because an insufficient number of channels was available. A second DMA chip was added for 286-based computers. Just like the second IRQ chip, these two are cascaded, allowing a total of eight DMA channel assignments (usually referred to simply as DMA channels). The floppy disk drives on all computers use DMA channel 2."
