Code 12 recourse lack with PhysX card, Geforce 6800 GT and Abit

Code 12 resource lack with PhysX card, Geforce 6800 GT and Abit

I know this is an old thread, but I am experiencing a similar code 12 recourse problem as Karma did back I 2004.
I had an Abit IC7-G motherboard and a Geforce 6800 GT video card and Everything worked fine. I recently bought an Ageia PhysX card from BFG Tech and when I plugged it in there were no recourses left for my Geforce 6800 GT card (result: lowest resolution and 4 bit colour in Windows XP Pro, conflict between CPU to AGP controller and VGA Save). As soon as I remove the PhysX card everything works fine.
I have tested the PhysX card in 3 others computers and the card works fine. One of these computers even contained a Geforce 6800 GT card but an Asus KV8 SE motherboard. When I replace my Geforce 6800 GT card with an ATI 9800 Pro the problem I gone.
I have tried everything and unfortunately I “burned” my motherboard in the process… my bad
I found a used Abit IC7 Max 3 motherboard in the local shop and started all over with a complete format and re-install. But when I plugged in the PhysX card… same resource problem. So it seems like it is the combination of an Abit motherboard (IC7 G or Max3) + Geforce 6800GT + PhysX card.
As Karma I have not been able to make any changes to the recourse configuration no matter what I do (BIOS or Windows). Everything is greyed out.

Can anybody give me a clue before I burn another motherboard

 

Problem solved

Installed PhysX card and cleared CMOS (Re-programed BIOS), Reduced AGP Aperture from 128 MB to 64MB. Booted and problem was solved. Went back to BIOS and increased AGP aperture to 256MB and everything still worked fine.
