Hello, I have a Tyan Thunder K8S S2880GNR and a Tyan Tomcat K8S S2850G2NR and they do not have any sound hardware on it, so the "?" can be replaced by a "-". Both do have a double ethernet interface by broadcom, so maybe in the network column should contain "2 x tg3" (this belongs to all Tyan motherboards with broadcom network interfaces). Flynn
