Chapter 5 VGA Setup

5.1 Introduction

The PCA-6187 has VGA onboard, you need to install the VGA driver to enable the function.

The Intel® 865G Graphics Memory Controller Hub (the 865G GMCH) provides an integrated graphics accelerator delivering cost competitive 3D, 2D, and video capabilities. The GMCH contains an extensive set of instructions for 3D operations, BLT and Stretch BLT operations, motion compensation, overlay, and display control. The 865G GMCH’s video engines support video conferencing and other video applications. The GMCH does not support a dedicated local graphics memory interface; it may only be used in a UMA configuration. 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 75Hz

•Maximum 3D resolution supported : 1600 x 1200 x 32 @ 85Hz.

•H/W motion compensation assistance for s/w MPEG 2 decoding.

•Software DVD at 30 fps Full Screen.

5.2Dynamic Video Memory Technology

The following is quoted from "Intel® 865G Chipset Dynamic Video Memory Technology", document number : 253144-001 :

The method of memory allocation where the Operating System, Applica- tion and Graphics Memory come from a unified System Memory pool known as Unified Memory Architecture (UMA).

Dynamic Video Memory Technology (DVMT) is an enhancement of the UMA concept, wherein the optimum amount of memory is allocated for balanced graphics and system performance, through Direct AGP (known as Non-Local Video Memory, or NLVM), and a highly efficient memory utilization scheme. DVMT ensures the most efficient use of available memory – regardless of frame buffer or main memory sizing – for maxi- mum 2D/3D graphics performance.
