Applies to all graphics cards of the XHR series, such as XHR, XXHR, Orion, Alpha, Spectra, Omega, Gemini:

These graphics cards are subsystem cards that are unusable for new 32-bit operating systems. None of the older graphics cards have their own BIOS and therefore cannot be recognized when booting. An additional VGA card is required for booting. These cards were only addressed by the driver integrated in the CAD application. There are no drivers for Windows 95 or 98 or Windows NT 3.5x, 4.0 and 2000.

As the chipsets of these cards accelerate the processing of vectors, they are not suitable for setting up the Windows desktop. For these graphics chips, the desktop would consist of an infinite number of pixels, the number of which - e.g. at a resolution of 1280 x 1024 - exceeds the million mark. This would slow down the processing speed infinitely.
