I setup the BIOS....Go in to Power Managment and switch the Video off Option to Always On and then is OK...
Let me know when its working.
Sorry for my Englisch....I work on this (Is not a BIOS Problem) :-)
Please have a Look on my German CAR-PC Forum

I have found a perfect CAR-AMP with Digital 5.1 and DTS (see the PIC)
