I was fallowing the xilinx quick start guide to get a constraint file there there apears to be 2 & I got the 500 instead of the 250 board what one should I chooze?

You have a 2.04 board I believe so you are going to want to select the 2.03+ ucf file.

The ucf file is the same for the 250K and the 500K part, the only difference is when you are starting a new project, you want to choose the SC3S500E part instead of the SC3S250E part.

If you already have a project started you can just right click on the project and choose properties to change the part from a 250K part to a 500K part.
