Afaik the SuperIO chip used in the Cobalt implements those registers but due to missing external circuitry touching some of these registers is dangerous. Afaic that is the case for the PS/2 keyboard/mouse controller ports. So those should be marked as reserved. The remaining registers are implemented just not terribly useful, so I think what he have is probably right as it is. Ralf
