Applicable to: Canada, United States


These are the latest drivers for Mwave-equipped 2134/2144/2168/2176 Aptiva systems which were preloaded with Windows 95 as the operating system. These drivers provide 33.6Kbps data capability and Direct Sound 3 compatibility. Users of 2144 and 2168 Aptiva systems MUST upgrade the AudioStation and Aptiva Communications Center software after completing the Mwave upgrade. Failure to do this will cause problems with this software. These drivers are NOT applicable to the 2159 systems or the 2176-C6Z/9R1 or 2176-C6V/9R2. These drivers were designed for Microsoft Windows 95, and as such are not compatible with Microsoft Windows 3.1, Windows NT, Windows 98, or IBM OS/2. (US/Canadian English)
