Chapter 5 AGP VGA Setup
5.1 Introduction
As quoted from "Intel® 845G chipset Graphics Chipset Controller Hub (GMCH) Rev. 1.0 May 2002.”:
The Intel® 845G Graphics Memory Controller Hub (the 845G GMCH) is Intel’s first memory controller hub with integrated graphics for the Intel Pentium® 4 processor. The 845G GMCH, with its new architecture graphics engine, delivers not only high 2D/3D graphics performance, but also provides efficient, high bandwidth communication channels connect- ing the processor, the memory, the I/O subsystem, and other components together to deliver a stable mainstream desktop platform solution. The features include:
•
•Integrated 350MHz RAMDAC that can directly drive a progressive scan analog monitor up to a resolution of 2048x1536 at 60MHz
•Up to 1600 x 1200 x 32 resolution at 85 Hz refresh.
•H/W motion compensation assistance for s/w MPEG 2 decoding.
•Software DVD at 30 fps Full Screen.
