So you end up with a circle of finger pointing where the user points to the OS manufacturer. The OS manufacturer points to the hardware. The hardware will point to the user for using the hardware outside of its specific 'recommendations' which you thought was a EULA. After a long set of time.. no one is happy and a lot of money/time was lost on something which can't be fixed. So the hardware gets dropped from the OS vendor's supported line to stop the circle. It doesn't make the customer any happier.. but they weren't going to be anyway. > This Board is 4 year old and now??? > > I mean it is in many server boards. > > -- > mit freundlichen Grüssen / best regards, > > Günther J.
