help onstalling opengl

HI, i am using win 2000 on a olivetti extrema 4000 with opengl 1.0....how can i upgrade to opengl 1.2 ? the home of sis 630 chip (the card i use) does not have support..
how can i set the lib manually ? (sorry for my english) thanks

win2k installs the openGL1.1 libs. To get 1.2, you'll have to get a geforce card or radeon. 1.2 is Not supported in software.

The problem is that my win2k has opengl 1.0..... i'll love to have the 1.1....
thanks
