Hi,
It is hard to say what could be happening from this.  Can you paste the output of the session including the install script and any other commands run.  Make sure that you are root while running the install.  Also do you see any information in /proc/pci, /proc/ioports, /proc/interrupts that show the board?
Hope that helps out.  
Best Regards,
