Tuvshuu:
Although I have not used it in a very long time, there is a free software utility "Config Reg Calculator" offered by Boson, which "allows you to determine what a router will do given the configuration register value".
It is available at:
http://www.boson.com/FreeUtilities.html
Perhaps it might be of interest to you.
Best Regards,
Mike
