So it can be ignored as well as the ASPM. I will check the cables, when I can get hands on the machine - just out of curiosity. > I wish I had some good ideas for you, but I don't know anything about > the SATA side.  I googled for "1068 ssd sata 1.5 gb/s" and found a few > hints about system firmware, LSI firmware, etc, but nothing concrete. > Yeah, if it were so easy, I wouldn't be bothering you. > I think some controllers have a BIOS setup user interface; have you > poked around in there? I have not seen the bios of the machine for many years. I was looking forward to plug it to a console, so that I can reboot remotely, but for some reason it was not possible. It was may be 5y ago. I will definitely double check this, allthough there will be nothing regarding SATA3.3 there as these were build many years before SATA3.3 saw daylight. As mentioned in the other posting I will attach those SSDs directly to the mobo. There are 6 SATA ports there. I think this is the best approach. But you know curiosity is a force you can not resist, so I still want to know why?! :) Thank you anyway BR -- FCD6 3719 0FFB F1BF 38EA 4727 5348 5F1F DCFE BCB0
