How can I get my T510 to boot when docked using an external display attached to the docking station??

When I navigate to the BIOS area mentioned above I get these three options:

ThinkPad LCD

Analog (VGA)

Digital on ThinkPad

But they do not make the BIOS boot on an external display on the dock, only displays attached directly to the notebook. The help displayed on the right indicates that I should select one of these options:

Digital 1 on Dock

Digital 2 on Dock

However, neither one of these options is available in the list of options I can choose, only the 3 I mentioned above.
