       /IMAGE_PATH=directory-spec

    Specifies the search path for the debugger to find the files that
    contains the debugger symbol tables (DSTs). The files must be of
    type .DSF or .EXE, with the same name as the image names in the
    dumpfile. For example, if image name foo.exe is in the dump file,
    then the debugger searches for foo.dsf or foo.exe.
