Cyrix Media GXM CPU up to 300MHz.
For me, it is a National Geode gx1 200MHZ and cs5530 but it should be nearly the same ;) National build that stuff :D
There are other revisions with Cyrix Processors, Cyrix Southbridge and a older cyberpro grafik (2010 I think) called stb1030
the SuperIO is the same
NSC CS5530 or Cyrix CX5530 Southbridge NSC SuperIO PC97137 Cyberpro 500x Video Chipset
