IIRC there where WinNT drivers also. The 4D50T is a bit odd. It is a pure GFX accelerator. It has a mezzanine PCI card stacked on top with a simple VGA chip. The VGA does all video (e.g. console text mode) until the Xserver with the right drivers is started. Then the VGA is switched off and the signal from the 4D50T is looped through to the monitor. It needs two PCI slots because of the VGA mezzanine PCI card and the large heat sinks on the GFX chips. There are DIMM slots for texture RAM... I found some GFX benchmarks that showed that the 4D50T is in par with the SGI SolidIMPACT. -- tsch??, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz/
