Isn't memory optimization supposed to mean loading commonly used drivers into upper memory, so that as much conventional memory as possible can be freed up? I don't know how to load commonly used drivers into memory. Please explain, and be a bit more detailed. (I also have some memory management tools, but I don't know how to use them.) Also, why is UMBPCI introduced in "Using DOS" as a system file? How exactly do you use it?? I can't understand it!!
