- You can still increase the total amount of physical and virtual memory
- with this trick: you can turn 4 MB of phys. memory into 2 MB of available
- phys. memory plus 4 MB of additional virtual memory (provided the stacking
- factor is as good as 2). So you'd have 6 MB for your programs.
-
- Despite the drawback in speed and the obvious degree of absurdity which
- gave rise to dissuading comments this may still help in certain situations
- when otherwise memory-consuming programs would not be able to run. It may
- still be more advisable in those cases to keep the 4 MB of real memory and
- set up your swap file on disk.
