Q: Sandra detects my AGP Video adapter as PCI!
A: If the adapter does not report any AGP capabilities (not even a header block) then it is really a PCI design adapted to work with AGP - probably an early one. AGP adapters support advanced data transfer modes and texturing which yours lacks. Technically it is not an AGP adapter. Just because it uses the AGP connector does not mean much. It has to be designed specifically for AGP if any improvements are to be realised.

Another possibility is the AGP runs off the PCI controller, so while the card is AGP, it still detects through the PCI bus.
And a 3rd possibility is your chipset drivers may be installed incorrectly.
