It was a PCI video card, and worked fine. In theory, any PCI slotted dock should accept a video card, and treat it as a second output device. I had a 2000 profile set up that if I ever booted with the dock connected, it even set the Voodoo 3 as the primary monitor and disabled the onboard card. It did not run the video through the LCD though, that was always controlled by the onboard chip.
