After looking for a few forums, it appears your onboard card might have pixel shader 2.0, but it missing something called vertex shader, or something like that. It would figure that 2142 would implement all the newer graphics technologies, so you might be stuck.
You could try updating to the newest drivers for Intel onboard video "card."

Most people seem to find a need to upgrade from their onboard video in the forum posts that I read. Onboard video is usually meant just to provide the ability to play videos, pictures and text, but not really meant to power most of the more recent games. If it was, graphics card companies like ATI and Nvidia wouldn't be coming out with new cards every 6 months or so.
