Drivers for PCI device

Good day. I recently upgraded to windows 7 64bit from xp and attempted to reinstall the drivers. The ATI display is of the 7000 legacy series and I found a driver that works(Installs fine and shows up under Display in Device Manager and I get to change the screen resolution etc, however no DX components were available. I saw a PCI device listed under unknown devices with Ven 13F6 and DEV FFFF but I was unable to locate the drivers for it. Any help would be appreciated greatly. Thank you
