A. When NT detects a video card it insists that you click the "Test" button. If the NT installation procedure incorrectly detects the hardware then it can cause the NT installation to hang and the only way to continue is to press the Reset button (e.g. the Number 9FX Reality card). To solve this problem when it detects the card just click the CANCEL button and it will leave the default VGA driver.
After the installation has finished manually install the new driver supplied with the graphics card, or download it from the makers web site.
