Dynamic Video Memory Technology (DVMT)
DVMT enables enhanced graphics and memory performance through highly efficient
memory utilization.
DVMT ensures the most efficient use of available system memory
for maximum 2-D/3-D graphics performance.
Up to 256 MB of system memory can be
allocated to DVMT on systems that have 512 MB or more of total system memory
installed.
DVMT returns system memory back to the operating system when the
additional system memory is no longer required by the graphics subsystem.
DVMT will always use a minimal fixed portion of system physical memory (as set in the
BIOS Setup program) for compatibility with legacy applications.
An example of this
would be when using VGA graphics under DOS.
Once loaded, the operating system
