If any other program writes to this memory area, a system error may result. ► Video BIOS Cacheable Select "Enabled" to allow caching of the on board video BIOS which may improve performance. If any other program writes to this memory area, a system error may result. ** VGA Setting ** ► PEG/Onchip VGA Control This option is used to enable or disable PCI Express graphics card or onboard VGA. ► On-Chip Frame Buffer Size This pre-allocated memory selection is supplied for legacy VGA and SVGA graphics support and compatibility. Upon boot, the system BIOS will pre-allocate the amount selected (8MB) from the top of the main system memory, which will be dedicated for VGA/SVGA graphics. The VGA graphics memory is needed for applications run from a Microsoft MS-DOS or legacy operating system, where there is no Intel Graphics Driver loaded. ► DVMT Mode Dynamic Video Memory Technology (DVMT) dynamically allocates system memory for use as video memory to ensure the most efficient use of available resources for maximum 2D/3D graphics performance. The amount of video memory allocated depends upon the amount requested by the operating system. When the memory is no longer required, it is returned to the operating system for use by other applications or system functions. DVMT allocates memory based on system needs. This BIOS option allows you to adjust the amount of memory available for DVMT. Fixed is a memory allocation method addition to the Unified Memory Architecture (UMA) concept, wherein a static amount of page-locked graphics memory is allocated during driver initialization. This fixed amount of memory will provide the user with a guaranteed graphics memory at all times, and will no longer be available to the OS. DVMT is an enhancement of the UMA concept, where in the graphics driver allocates memory 33
