Don't do this.


Read this:

http://trac.openlayers.org/wiki/FrequentlyAskedQuestions#Projections

then do this:

new OpenLayers.Map("map", {maxExtent: new
OpenLayers.Bounds(2574985.815002, 5646323.449916, 2587295.900005,
5655021.169988),
maxResolution: 'auto', units: 'meters', projection: "EPSG:41001"});

combined with something like:

> var bounds = new OpenLayers.Bounds(2574985.815002, 5646323.449916,
> 2587295.900005, 5655021.169988);
> map.zoomToExtent(bounds);
