HP Integrated OpenGL Interface Board
HP Integrated OpenGL Interface Board
OpenGL is a graphics language for describing three-dimensional objects.
The HP Integrated OpenGL Interface board has a processor that executes
OpenGL 3D graphics instructions autonomously of the main processor.
• The graphics controllers cannot be upgraded or reconfigured by the user,
or by HP personnel.
• Changes to the configuration are not supported. Make sure that the
jumpers and daughter board are configured as set by the manufacturer.
