openGL and counter-strike 1.6

I played counter-strike 1.6 and openGL while I had windows 98. After I upgaded to windows xp openGL no longer worked. How do I get it to work again? Is it possible?
I have to run in software mode, which is ugly.
When I try and switch to openGL I get this error
Video mode change failure - The specified video mode is not supported. The game will now run in software mode.

I have Intel® 82815 graphics controller.
Please help me out if you can. Thank you.
