Integrated Graphics Subsystem

The total memory allocation is determined by the amount of system memory installed in a system, along with the BIOS settings, operating system, and system load. Table 6-1 shows the pre-allocation memory amounts.

System memory that has been pre-allocated is not seen by the operating system, which will report the total amount of memory installed less the amount of pre-allocated memory.

Systems running Windows Vista or Windows 7 use Protected Audio Video Path (PAVP) to ensure smooth playback of high-definition video by off-loading video decoding from the processor to the integrated graphics controller. BIOS can allocate addtional memory for PAVP, which can be set through RBSU to run in Lite mode (default) or in Heavy mode. Table 6-2 shows the PAVP memory usage for Windows Vista and Windows 7.
