6.2.3 MEMORY MANAGEMENT
The 815E-based graphics controller uses a specific amount of system memory allocated as
follows:
Video BIOS – 512 or 1024 kilobytes. An OS report of available system memory will be the total
amount installed LESS this amount.
Graphics Memory – Prior to the PV 4.x driver being loaded, the graphics memory will be one
megabyte for supporting standard VGA modes. After driver load, memory allocation will be set
by the Dynamic Video Memory Technology (DVMT) for rendering, Z-buffering, and displaying
according to need and total system memory availablility. Assuming the presence of 4 megabytes
of display cache (standard on these systems) the following amounts will be allocated:
♦ w/Windows 98 and 32 megabytes of system memory – 9 megabytes
♦ w/Windows 98, NT 4.0, or 2000 and 64/128 megabytes of system memory – 12 megabytes
