Windows 2000 has set up 2 PCI Standard PCI-PCI Bridges on my machine. One is associated with my AGP video card. The other is associated with my Ethernet card installed in a PCI slot. This causes a conflict that is only resolved by disabling the bridge for the NIC. This is the only way the Video card works! Is there a cure?
I've tried installing XP with the same results.
 
Move the PCI Ethernet card to another slot. It sounds as though you are using the PCI slot next to the AGP slot ... anyway, try another.

Been There Done That

I Did this. twice. That didn't work. As I've explained: Windows has allowed two PCI Standard PCI to PCI Bridges to exist in device manager. It is my understanding that sometimes AGP problems exist with athlon processors but I don't know if this has any specific relation to the Bridges.
 
Sorry, but now you need to give me more info on the PC ...

The only thing this doesn't show is the PCI Standard PCI-to-PCI Bridge duplication and it's associated connected devices.


Thanks,
