DVMT ensures the most efficient use of available system memory for maximum 2-D/3-D graphics performance. Up to 224 MB of system memory can be allocated to DVMT on systems that have 512 MB or more of total system memory installed. Up to 128 MB can be allocated to DVMT on systems that have 256 MB but less than 512 MB of total installed system memory. Up to 64 MB can be allocated to DVMT when less than 256 MB of system memory is 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 and graphics drivers allocate additional system memory to the graphics buffer as needed for performing graphics functions. NOTE The use of DVMT requires operating system driver support. 22
