You<br>must install the NT 4.0 drivers off the CD, then reboot, it will NOT be<br>detected as a modem but under the system manager it shows Zoom 56k v.90<br>LTWinmodem (however its disabled). You must select it and open its<br>properties, then you have to update the drivers to a Zoom 56k LT<br>Winmodem. After that hardache it runs PERFECT!
