- DOS doesn't have a 640K barrier. DOS will use as much CONTINOUS memory it
- can find. Since the upper 384K of the 1st meg. is reserved for hardware,
- (and bios) DOS can only "see" 640K. One thing that may be possible is
- to use to 386 memory mapping to fool DOS into thinking that more memory
- is availiable, and then having a device driver handle the mem. swaps.
