The Layer.WMS constructor takes 4 arguments: name, url, params and
options. visibility:false and isBaseLayer:false have to go in the
options (4rd) argument:

var wms = new OpenLayers.Layer.WMS.Untiled(
    "Plan 1924",
    "http://localhost/cgi-bin/mapserv.exe?map=C:/ms4w/Apache/htdocs/osnamap/includes/wms.map",
    {transparent: true, layers: 'plan1924'},
    {isBaseLayer: false, visibility: false}
);


Regards,
Andreas.
