    LOAD_SYS_IMAGES controls the loading of system images described
    in the system image data file, VMS$SYSTEM_IMAGES. This parameter
    is a bit mask.

    On Alpha and Integrity servers, the following bits are defined:

    Bit                         Description

    0 (SGN$V_LOAD_SYS_IMAGES)   Enables loading alternate execlets
                                specified in VMS$SYSTEM_IMAGES.DATA.

    1 (SGN$V_EXEC_SLICING)      Enables executive slicing.

    2 (SGN$V_RELEASE_PFNS)      Enables releasing unused portions of
                                the Alpha and Integrity servers huge
                                pages.

    These bits are on by default. Using conversational bootstrap exec
    slicing can be disabled.

    On Alpha and Integrity servers, LOAD_SYS_IMAGES is an AUTOGEN
    parameter.
