What Happened To XGI Graphics?
 

XGI Technology is still in business, but what has happened to
them? We once saw hope in them for providing discrete graphics

discontinued their Volari 8 series. While they're no longer producing
these desktop chips, they remain an active player in the server and
embedded graphics industry -- accompanied by their open-source driver.
