Memory Hole

Some (unusual) expansion cards require access to particular memory addresses in order to function properly. This parameter lets you set aside the appropriate area of memory for these cards. The typical memory areas that can be set aside are "512-640KB" (the upper 128K of conventional memory) and "15-16MB".

This setting should be disabled unless you have a card that you know requires this setting. The default is normally "Disabled".
