Hi mazhar.ali,
Which versions of Measurement and Automation Explorer (MAX) and FieldPoint do you have installed? You can find out by opening MAX, expanding the Software category under My System, and clicking on Measurement and Automation Explorer and FieldPoint, respectively. If you have a MAX version 3.1.x or greater, you can follow the instructions
here. When you get to the LabVIEW Real-Time Software Wizard, click the "Update BIOS..." button to update the firmware. Hope this helps!
