Hm, doslib, I downloaded this huge package some months ago but didn't have time yet to discover whats's all inside, seems to me a bit kludgy...

I just opened floppy.c and at the beginning of file I see
#include <hw/8237/8237.h> /* DMA controller */

this doesn't persuade me that this code don't use DMA...

EDIT: there seems to be maybe something nondma too:
floppy_controller_wait_data_write_non_dma_ready()
it will need a closer look. Maybe that code implements both DMA and non-DMA modes...

DOS gives me freedom to unlimited HW access.
