I am not sure older vfx board are supported on the newer OS lines from windows. They may have been EOL'ed (end of life) prior to release of win 7 itself and newer releases like 2008 or 2012. As that model would have been replaced by newer HW at the time (likes of D/4pciuf for example). So it may not have been tested at all, not sure though. What is the specific model number of the board and serial number (two letters followed by 4 digits (and I can try and check).
