emm386

DEVICE=C:\DOS\EMM386.exe	emm386 creates expanded memory without having an expansion card. emm386 emmulates the expansion card by using extended memory on Intel 80386 CPUs. Extended memory should not be confused with expanded memory (an earlier method for expanding the IBM PC's memory capacity beyond 640 kb using an expansion card with bank switched memory modules). Extended memory is a way for DOS to access memory on the motherboard through an application programming interface called the eXtended Memory Specification (XMS). HIMEM.SYS takes care of memory management and copying memory between conventional and extended memory. emm386 uses the API to simulate an expansion card. Because of the available support for expanded memory in popular applications, device drivers, such as emm386, were developed that emulated expanded memory using extended memory API.
