Tip T2524 - The AGP aperture size may not be set properly. Generally the AGP aperture size should be at most equal to system memory and generally lower. While the GART driver will allocate memory to be used for AGP dynamically it is good to set an upper bound in order to maximise memory utilisation. In any case, it should not be disabled.
Fix: Go into BIOS Setup and change it to match system memory size or set it lower, e.g. 64MB. Note that some adapters may work better if you set it to the maximum value 256MB, or at least 64MB. Consult the video board manual for more details.
