A method and apparatus which puts a cartridge memory, such as a cartridge ROM, into the EMS memory space. A register value is set to indicate that the cartridge memory is present. This value is provided to enable a logic circuit which does the address transformation needed for EMS and generates a chip select signal for the cartridge memory. The chip select signal is produced upon the detection of an address directed to the cartridge memory. A register stores the address of the cartridge memory. Since the memory address of the cartridge memory can be varied, the location of the cartridge can be placed where it is most convenient for the particular memory structure of a system.
