                           PerformBackfill=<Boolean>
Default:        Auto (Windows automatically checks to see if it needs to
                fill in memory  based on how DOS is occupying memory.)
Purpose:        Specifies whether or not to allocate a full 640K of memory
                to a computer that has less than 640K of base conventional
                memory. Enabling or disabling this setting overrides the
                automatic checking done by Windows.
To Change:      Use Notepad to edit the SYSTEM.INI file. (You should never
                need to change this setting, because Windows can
                automatically detect whether or not to perform a backfill). |
