                             PREMIUM EXEC AND EMM386.EXE

    MS-DOS version 5.0 includes an expanded memory emulator, EMM386.EXE.  Memory
    addressing conflicts may occur when running this program on the Premium Exec.

    The problem is a result of  EMM386.EXE and the Premium Exec System BIOS
    attempting to load at the same memory address.

    To prevent EMM386.EXE from using memory that is already used by the Premium
    Exec System BIOS, add the following parameter to the device statement in the
    system's CONFIG.SYS file:

        DEVICE=EMM386.EXE   x=C000-CFFF
