Stuck in BIOS at booting
Just a thought but maybe disconnecting the PCI bus items. The Image Processor and the Cine Bridge. Leave the Display Adapter installed. Toggle the silver switch on the Display Adapter PCB and then boot. It should show the boot on the monitor. Also maybe one of the PCI devices are hanging you up?
If you have an email send it to me and I will send you a picture.
I have exactly the same issue. Did you ever find a solution?
Sorry for my late reply, yes it turned out to a defective CINE board.
