3gb switch breaks map-image-insert for georeferenced raster images

1.  Take a computer with 4GB RAM.
2.  Start the OS with the /3GB switch enabled *
3.  Start Civil 3D 2008
4.  Map-Image-Insert
5.  Select a tiff with a world file attached, or a SID file
6.  Let the error messages begin…

Note – this behavior also takes place when using x64 Windows (which doesn’t require the /3GB switch) as noted on “Civil 3D for Beginners”

Workaround:
Either don’t use /3gb switch with the OS or use Raster Design to insert georeferenced raster files.  Alternately, you can try to use the Add Raster Image or Surface Connection from the Map Task Pane.
