Thinkvantage button as OS selector on boot - possible?

[icantux]

Anyone come across any info on the possibility of making the blue Thinkvantage button to act as a OS boot selector on machine startup?

Say if a user has 2, 3 OS-es is there a way to configure that blue button to choose which one to boot into?

Googled this subject but can't find any definitive answer.
