This is an original driver from a restoration CD for the Crystal Audio CS4235 audio chip - built into the motherboard.
This was used on many different PC manufacturers. I have had personal experience seeing this on HP, Compaq, EMachines and Packard Bell.
This is for Windows 95 and Windows 98.
Unzip, and run SETUP in Windows.
For Windows 95 you MAY have to install this from Device Manager.
