How about: (in psuedo-code)

#ifdef DOS
    fopen ("/CONFIG.SYS", "r");

    fscanf (..., "FILES=", ...);

    fscanf (...,  value, ...);

    fclose (...);
#else
    other method appropriate for architecture
#end

Since all DOS machines have to have CONFIG.SYS in the root directory, it
would work for any DOS box.  If the fopen fails, then assume the default.
