    3 Make sure that no Xilinx software is running on the Windows PC, then switch the FPGA's master power switch to the ON state.
     3In this section, you will establish a USB connection between the WARP FPGA board and the PC on which you are running the Xilinx software tools.  The USB connection is the link through which the FPGA on the WARP board will later be configured.

    5 '''If this is the first time that a WARP FPGA board has been connected to the PC, Windows will "discover" new hardware.  PLEASE NOTE THAT YOU MAY EXPERIENCE SEVERAL ROUNDS OF HARDWARE DISCOVERY AS PART OF THE INSTALLATION PROCESS.'''  This is normal, since each round of hardware discovery and driver installation allows a subsequent "downstream" USB device to be seen by Windows.  Each round of hardware discovery and driver installation should be handled in exactly the same manner - simply allow Windows to install any required software automatically.  The following screen snapshots illustrate a typical sequence of steps encountered during a single round of hardware discovery.  Please keep in mind that you may encounter several similar rounds of hardware discovery as part of the installation process.  '''When Windows has completed the process of hardware discovery and software installation, you will receive a pop-up message to indicate that your hardware has been installed and is ready to be used.'''
