DMA in it's current form can only support floppy disk drive operations. This should be changed, so that it can be used for other I/O devices

Changed name to reflect this change is needed for ISA DMA, since PCI devices can implement DMA read/write on their own.

Moved to 1.4 OS Release.
Modification needs rework of whole ISA DMA with additional management functions for this memory region.
