ultra 20 m2 and nforce chipset

What nforce chip does the ultra 20 m2 use? Its the 03-M2 config . I cannot find anywhere what particular chipset is being used. I want to download the latest drivers from nvidia.com for the correct version...

Well the motherboard is a "Tyan Tomcat K8E S2865".There are variants of it but after some Google research I think it hasthe chipset: nForce4 core-logic SMSC DME1737By the way: tyan.com is extremely slow
