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 ?
