Memory
Graphics memory is shared with system memory. Graphics memory usage can
vary from 8-128 MB depending on the amount of system memory installed
and system load. 8 MB is pre-allocated for graphics use at system boot time.
Additional memory is allocated for graphics using Intel's Dynamic Video
Memory Technology (DVMT) to balance the optimum amount of memory
between graphics and other system use.
Memory < 256 MB: 8 MB pre-allocated (for DOS) + 24 MB DVMT : max frame
buffer of 32 MB
256 MB <= Memory < 512 MB:8 MB pre-all 56 MB DVMT: max frame
buffer of 64 MB
512 MB <= Memory: 8 MB pre-all 120 MB DVMT : max frame buffer of
128 MB
Controller Clock Speed
333 MHz
