Intel's i865G reserves chunk of system memory either 1, 4, 8 16 or 32 MB in size as its video memory. If necessary, the driver can also allocate up to 32 MB more memory via DirectAGP, the same way an application would. When the additional memory is no longer required, it is released again and made available to the operating system. This puts the chip's maximum available memory at 64 MB. Intel calls this technique "Dynamic Video Memory Technology 2.0."
