No agp bus , video card is on pci bus ?

[barginhunter]

I have three simular systems , 2 - Epox 8rda+ and 1- 8rda , in two of the three under system devices there is a nforce agp bus listed , in one system there is not ( 8rda ) . In the system without the agp bus the gpu listed location is pci bus 2 , device 0 , function 0 . I cannot choose 8Xagp in the video card options tab.
Can anyone explain this ? I have tried different video cards ( known good ) , restored winXP back to original install date , tried the nvidia chipset drivers 3.13 , this one board appears not to be capable of having an agp bus ?

tried latest bios maybe?

[barginhunter]

All three systems have the latest bios updates .

Anything stated in the manual about it? What are the differences in the two types of motherboards?

[barginhunter]

Far as I know the only difference between the 8rda+ and plain 8rda is firewire support , better sound and built-in lan .

Fixed it , I read on the net you could reinstall winXP , I didn't want to do that , too much trouble .
In device manager / system devices , I was able to manually reinstall the nvidia agp bus .
Now my agp card is running @ 8X and benchmark video scores are much higher .
