Which direct memory access channel is used for the floppy controller?

"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."
