your changes will be discarded.
The new numbering takes effect when you restart the system.
Notes

Board settings, especially video custom properties such as Crop, Logo, and Captions settings,
are linked to board PCI addresses rather than to board numbers.

After you renumber boards, you may have to re-set your volume levels. On Microsoft
Windows XP platforms, you may also have to re-select your audio inputs.

When you add a new board, especially a board with complex PCIe topology such as an
Osprey 450e, the PCI addresses of boards already in the system may be altered. This change
may cause the driver to renumber boards that were already in the system. Use the Board
Numbering dialog to set numbers the way you want them. You may have to manually adjust
board settings such as video custom properties when boards are added or removed.
