Asus Vintage PE-1 is not a Graphics/Video Adapter, it's a barebone pc system. And Asus does not list any Graphics/Video adapter for it.
Is this video adapter integrated on the motherboard or a pci/agp add-on card? We need some details on the hardware device you need a driver for before we can offer help.
Open Device Manager, double-click the video device, click the Details tab and give me the 1st line of text (eg: the hardware id string).
