Intel® 815 Chipset: Graphics Controller PRM, Rev 1.0

R

3.After the conclusion of the graphics driver startup code the internal graphics functions will be ready for run-time activity and commands can be written into the ring buffer.

2.3.1.4.Switching Device modes

Under normal conditions, the GMCH Device Mode will be switched at most once: from AGP to Internal Graphics mode (via APCONT[0]) when no external AGP graphics device is present. This is handled automatically by the system BIOS during system initialization. There is no case where the GMCH will be switched from Internal Graphics mode to AGP mode.
