Instruction for compatility with models other than s3e500

I am testing JOP on my old s3e1200 and had mapping issues. Xilinx didn't raise very informative error but I resolved the issue by this way so I want to share it with others. I do not know about more fashionable way to auto detect and use correct pin (seems this is possible with single UCF) but I think this can be helpful for someone like me.
