All About EMM386 Windows command
EMM386 is a Windows command that allows access to the computer’s extended memory, providing more memory for applications and optimizing system performance. It is commonly used in older versions of Windows to enable access to memory above the 1 MB limit. By loading EMM386, users can take advantage of Expanded Memory Specification (EMS) and Extended Memory Specification (XMS) to enhance the efficiency of their systems. EMM386 can be configured with various options to customize its behavior and allocation of memory resources, making it a useful tool for managing system memory on compatible Windows operating systems.
