Depending on the hardware, there will be a memory "hole" between 640k and 1M of 384k. If your hardware has this "hole", then you can, on some hardware, "back fill" the hole by taking memory from the top of memory and remapping its location into the hole. You should not do this for BSD or for Win95. You should not do this for DOS, either, if you are running an extended memory mamanger of any kind. This is typically required only by very old DOS programs that use expanded memory but can't use extended memory.
