Integrated Graphics Subsystem The integrated graphics controller will use, in standard VGA/SVGA modes, pre-allocated memory as a true dedicated frame buffer. If the system boots with the OS loading the Extreme Graphics drivers, the pre-allocated memory will then be re-claimed by the drivers and may or may not be used in the "extended" graphic modes. However, it is important to note that pre-allocated memory is available only to the integrated graphics controller, not to the OS. The DVMT function is an enhancement over the Unified Memory Architecture (UMA) of earlier systems. The DVMT of the Q57 selects, during the boot process, the maximum graphics memory allocation possible according on the amount of system memory installed: The actual amount of system memory used in the "extended" or "extreme" modes will increase and decrease dynamically according to the needs of the application. The amount of memory used solely for graphics (video) may be reported in a message on the screen, depending on the operating system and/or applications running on the machine. For viewing the maximum amount of available frame buffer memory MS Windows go to the Control Panel and select the Display icon, then > Settings > Advanced > Adapter. The Microsoft Direct Diagnostic tool included in most versions of Windows may be used to check the amount of video memory being used. The Display tab of the utility the "Approx. Total Memory" label will indicate the amount of video memory. The value will vary according to OS. ✎ Some applications, particularly games that require advanced 3D hardware acceleration, may not install or run correctly on systems using the integrated graphics controller.

Integrated Graphics Subsystem
The integrated graphics controller will use, in standard VGA/SVGA modes, pre-allocated
memory as a true dedicated frame buffer. If the system boots with the OS loading the Extreme
Graphics drivers, the pre-allocated memory will then be re-claimed by the drivers and may or
may not be used in the “extended” graphic modes. However, it is important to note that
pre-allocated memory is available only to the integrated graphics controller, not to the OS.
The DVMT function is an enhancement over the Unified Memory Architecture (UMA) of earlier
systems. The DVMT of the Q57 selects, during the boot process, the maximum graphics memory
allocation possible according on the amount of system memory installed:
The actual amount of system memory used in the “extended” or “extreme” modes will increase
and decrease dynamically according to the needs of the application. The amount of memory used
solely for graphics (video) may be reported in a message on the screen, depending on the
operating system and/or applications running on the machine.
For viewing the maximum amount of available frame buffer memory MS Windows go to the

The Microsoft Direct Diagnostic tool included in most versions of Windows may be used to
check the amount of video memory being used. The Display tab of the utility the “Approx. Total
