How to Remove Expanded Memory Manager From DOSBox

Some games that were originally released for Microsoft DOS required use of expanded memory. MS-DOS had strict limitations on how much RAM could be used for running programs. The expanded memory manager allowed programs to access RAM beyond the first 1,024 kilobytes. DOSBox allows you to enable or disable expanded memory through a command line. It can also save the settings into a CONF file so you don't have to enter it manually every time you run the game.

Instructions

  Type "config -set "dos ems=off"" into the command line. Remember to remove the exterior quotation marks. Leave the quotation marks around dos ems=off.
