Graphics memory is shared with system memory. Graphics memory usage varies
depending on the amount of system memory installed, BIOS settings, operating
system, and system load. 32 MB is pre-allocated for graphics use at system boot time.
Additional memory can be allocated at boot time by the BIOS for PAVP (Protected
Audio Video Playback) support for playback of protected video content. For Vista, use
of PAVP heavy mode preallocates an additional 96MB.
Additional memory is allocated for graphics as needed using Intel's Dynamic Video
Memory Technology (DVMT), to provide an optimal balance between graphics and
system memory use.
