I used this driver on a NEC GT 100 with onboard audio. (ESS Solo 1 chip on Motherboard) Works fine. Download to folder on C . Locate folder and expand file (Use same folder.) Right click on My Computer, select Hardware tab, choose ? audio,
Select Change driver, direct to the folder you used to unzip the file. Once you accept the file, if windows comes back looking for a disk, redirect to the same folder.
