maybe more to do with your ATI...
You're right with this one.
After resetting the BIOS, removing additional cards (audio, network...), using an USB keyboard/mouse and swapping the memory, i tried changing the ATI card.
And yep, the installation ran without any hassle.
Why is it always the last thing you try that works?
Server is running now version 1004-20120701130826149 on a SSD.
The day after tomorrow i can start configuring it. Looking forward to the new things in LinuxMCE...
Very nice install iso !!!
