5.1 Introduction
The AIMB-740-B has VGA onboard, you need to install the VGA driver
to enable the function.
The Intel® 845GV Graphics Memory Controller Hub (the 845GV
GMCH) is Intel’s first memory controller hub with integrated graphics
for the Intel Pentium® 4 processor. The 845GV GMCH, with its new
architecture graphics engine, delivers not only high 2D/3D graphics per-
formance, but also provides efficient, high bandwidth communication
channels connecting the processor, the memory, the I/O subsystem, and
other components together to deliver a stable mainstream desktop plat-
form solution. The features include:
• Built-in 2D/3D VGA controller.
• Use Intel® Extreme Graphics Architecture
• 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.
