Have you installed the VMWare Tools? They should provide all drivers needed for the emulated hardware inside the VM. Not sure if version 6 of the VMWare Tools still support Windows 95, but you can also use older ones. If all fails, use Oracle VirtualBox instead, which is able to emulate a SB16.
The device manager should show the device driver in windows 95, if not then add it to the options before launching the virtual system. What host system are you using? Windows, Linux? is the host system compatible with that version of VMmware ? on your host, do you see the VMWARE VMCI host adaptor in system devices? (Win 7,8....) should work like a charm if its all there with no splats
