I haven't heard anybody claim that before. Can you substantiate this claim? Which motherboards have you used? What UARTs do they use? Did the patch work with all of them? In any case, code which doesn't recognize all UARTS is not *too* sophisticated. > So, developers of SIO driver should re-write a bit SIO code to fit new > chips. And break the old ones? At the moment, we don't know that this affects more than a fraction of all motherboards. Yuri wasn't confident enough to commit this patch (which, so far, has always worked), because he was afraid it might break the majority for whom the current code works. > I found somewhwre in maillist this link to apropriate patches: > > >> Yes, and add in some patches.

My version includes a little explanation.
