This file contains the drivers for both the Rockwell HCF 56K Data Fax PCI Modem and Riptide PCI Audio Device. If you need only the Modem drivers, unzip the file retaining the internal directory structure. You will find the Modem drivers in the Bits\HCF.W95 directory. Run the file (or Install.exe contained in the file) only if you need the Modem AND Sound driver upgrade. I don't know if this is a single product.
