You can check the documentation that came along with the board for pin-out details to the various components & connectors. Then in ISE, you invoke the Constraint editor and create a new UCF file.

You have to follow a syntax when creating the UCF file. Refer Xilinx manuals for that. You can specify pin-constraints, delays, and other types of constraints in the UCF file. After you create the UCF file, save it and add it to the project (if it does not get added automatically). Then compile your design. View the chip -pin view to check the pin assignments.
