Emm386 Ü ßßßßßßß The expanded memory manager (EMM) for 386 systems (or better). Syntax: EMM386 [on|off|auto] [w=on|w=off] on | off Turn expanded memory support on or off. Default=on. auto Only support expanded memory when a program asks for it. w=on | w=off Enables or disables support for the Wietek coprocessor. Default=off. Installing the EMM386.EXE device driver You must use the device command to install the EMM386.EXE device driver before you can use the emm386 command. If you try to use the emm386 command on a computer that does not have an 80386 or higher processor, FreeDOS displays an error message. Reactivating EMM386 expanded-memory support If EMM386.EXE was loaded when FreeDOS started but is not currently in use, the on parameter reactivaes expanded-memory options. Suspending EMM386 expanded-memory support If EMM386 expanded-memory support is currently active, handle 0 is the only handle allocated, and EMM386.EXE is not providing access to the upper memory area, then the off parameter suspends EMM386 expanded- memory support. When EMM386 expanded-memory support is off, the Lotus/Intel/Microsoft Expanded Memory Specification (LIM EMS) header is changed so that programs cannot use expanded memory. Enabling and disabling Weitek coprocessor support If the w=on parameter is specified and the off parameter (different from the w=off parameter) is not, EMM386 enables Weitek coprocessor support. The high memory area (HMA) must be available to enable Weitek coprocessor support. If you specify w=on or w=off and no Weitek coprocessor is installed, FreeDOS displays the following error message: Weitek Coprocessor not installed
