    PCIx-16 and Legacy PCI video

    I posted this in another forum, but maybe it is a more appropriate question to post here.


    Is it impossible to use a PCIx-16 video card, and a Legacy PCI video card togther.

    I know one uses Serial, the other (PCI LEgacy) uses P.

    From what I understand, it is ok to use PCIx16 and PCIx1, but not Legacy PCI.

    When i tried to install my Nvidia GEforce 8600GT and and ATI PCI 9250, my PC locked up shortly after Post.

    When the Bios saw the PCI card first, it i did not recognize the x16 at all. When I did the x16 first, it would just lock up mid way through booting into XP.


    Is there anywhere on the net that confirms 100% that you can not use PCI-16 and Legacy PCI together for video cards?

    Could also be that I am mixing Nvidia and AT?

    Thanks for listening to me rant....

    ATI drivers are historically bad at playing well with others.

    Personally i would stick to one vendor if i was doing this.

    As i said in the other thread, any problems are likely to be driver related rather than host bus related.

    Re: PCIx-16 and Legacy PCI video

    You CAN mix busses for cards.

    Asrock used to advertise one of their motherboards as capable of taking AGP, PCIe and PCI graphics cards all at the same time, giving 6 head video. I have also seen a walk through somewhere of someone running ATI and Nvidia cards at the same time on that board, but it didn't look like my idea of fun.

    Another vote here for driver conflicts.
