Global Allegro.cfg file

Hello,

I found an article that claims you can create a global allegro.cfg file and store it on a read only area of a server.  Then all that is necessary is to place the file path in the capture.ini file.  Does anyone know if this is true and if so what part of the ini file would this path go?

Thank you
