as Non-Local Video Memory (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 maximum
2D/3D Graphics performance. DVMT dynamically responds to system
requirements, and applications demands, by allocating the proper amount
of display, texturing and buffer memory after the operating system has
booted. For example, a 3D application when launched may require more
vertex buffer memory to enhance the complexity of objects, or more tex-
ture memory to enhance the richness of the 3D environment. The operat-
ing system views the integrated graphics driver as an application, which
uses Direct AGP to request allocation of additional memory for 3D appli-
cations, and returns the memory to the operating system when no longer
required.
The Intel Extreme Graphics Driver determines the size of the pre-allo-
cated memory needed and will make additional Non-Local Video Mem-
ory requests to achieve the amount needed for the display and application
requirement. The video memory size in the Intel® 845GV chipset varies
and is determined using several factors. The key factors are system
resources and system activity. The maximum video memory is up to
64MB SDRAM

1. Insert the driver CD into your system's CD-ROM drive. In a few
seconds, the software installation main menu appears, as shown in the
following figure. Under the "VGA DRIVERS" heading, click on one of
the buttons (labeled "W2K XP", "WIN9X ME", and "WIN NT" respec-
tively) according to the operating system you are using. The following
Note: Before installing this driver, make sure the CSI
utility has been installed in your system. See
