Anyone know what PCI mode is and how to turn it off.

This is most likely through the BIOS as only the old cards of the 3dfx Voodoo Banshee ilk used a PCI design for an AGP card which resulted in the loss of almost all AGP functions even though the card was in AGP format.
Things to look for in the BIOS (note any changes you make in the BIOS settings, if they don't help, change them back) include, 'AGP Aperture Size', a setting of 128MB is rec (but try 64MB or 32MB too), 'AGP 4x mode' should usually be enabled (you may have to change it from auto to manual), disable mobo and gfx caches (NOT CPU caches!) and shadows, Setting AGP1x (ie disabling AGP4x in BIOS) will hit perf, but not as badly as it sounds and may remedy the problem, disabe 'PCI Master Read Cache', and finally ensure your AGP has an IRQ assigned in the BIOS. Other than that I would suggest downloading the latest non-beta drivers (manu & chipset websites) for all your hw but particularly your mobo and gfx card. Although do bear in mind it can be older drivers which fix your problem (esp 21.83, 23.11, 27.xx, 29.xx). After each driver change you would be best to reinstall DX8.1 and possibly even use Detonator Destroyer inbetween installing new drivers.
Reinstalling the latest version of DX8.1 is rec, esp after an install of gfx drivers. You could try to run DXDIAG, Diplay Tab, DISABLE Direct3D Accel & CLOSE the app. RERUN DXDIAG & ENABLE Direct3D Accel. It should also tell you here if AGP functions are enabled ('DirectX Features' under the Display Tab). Leave the PCI slot next to the AGP alone, maybe try swapping your PCI devices through different slots, it's a good idea to have the PCI blanking plates at the back removed for ventilation anyway. It could be conflicts or resource problems, you could try disabling 'PnP OS' from the BIOS if you're using WinXP, apparently WinXP likes to do things itself. If you use any OS then perhaps setting PnP manually (reserving some resources) or resetting the PnP may also help. Try downloading NVMax. It has the infinite loop fix and other things for nvidia cards. http://www.nvmax.com/ http://www.charnleys.co.uk/NVmax4.exe
Is this a new quirk, have you upgraded the OS or added any new sw or hardware recently? What's the perf hit like in games?
