I have tried to install this card into a machine running Windows NT 4.0 server. After I install the drivers and restart the server. Windows reports it as a standard VGA adapter and wil only run in 640 x 480 x 16 colours. I have tried earlier revisions of drivers and have tried uninstalling the drivers via the add/remove programs option and then re-installing the drivers with no success. I have also tried following the instructions in MS Knowledgebase article Q157251 with no success. Any ideas would be greatly appreciated.
