Integrated Graphics Subsystem
6.2 Functional Description
The integrated HD Graphics controller (hereafter referred to as an internal graphics controller) featured in select Intel processors supported by these systems operates off the internal PCIe x16 bus of the processor and, through the Flexible Display Interface (FDI) and the Q57 PCH component, can drive an external analog

■DirectX DX10 support
■OpenGL 2.1 support
■Dynamic video memory allocation, where the amount of memory required by the application is acquired (or released) by the controller
■Intelligent memory management allowing tiled memory addressing, deep display buffering, and dynamic data management
■Core engine operating up to 900 MHz
■2560 x 1600 maximum resolution
The integrated graphics controller uses a portion of system memory for instructions, textures, and frame (display) buffering. At boot time, 32 megabytes of system memory is
