Description

The CS4614 is a high-performance pin-compatible upgrade to the 100-pin CS4610/11 PCI audio accelerator. With the added legacy compatibility modes, the CS4614 enables real mode DOS compatible PCI-only audio subsystems. This device, combined with application and driver software, provides a complete system solution for hardware acceleration of Windows 95 DirectSound, DirectSound3D, DirectInput, and Wavetable Synthesis. WDM drivers provide support for both Windows 98 and Windows NT 5.0.
