M1 ATX not working

I just bought Voom-2 Bundle (VoomPC-2, Jetway 1.5Ghz Mainboard, M1-ATX) connected everything by the book but nothing happens. It seemes that the M1 doesnt give a signal to the m/b. When I disconnect the J6 and manually push button down only the CPU fans starts but den computer doesnt boot. Tried with several powersources as well as a 12V lead battery. Same same. The computer seemes to work perfect with a normal ATX powersource. So what can be wrong. I see that the brain in the M1 is a PiC processor and I gather that the J6 is connected to one of the PICs ports and it doesnt give the right signal to the M/
B hence the PIC is gone. Is there anyway to test the M1:s function?

Thanks in advance

After some thinking, research and testing i found out that my M1 works. I tested the output of the M1 and found that all the suply rails was working alright after setting PS_ON low. Despite ok supply rails 3.3, 5 and 12 volt the M1 PSU didnt give the motherboard a PWR_OK signal. Hence the motherboard dont start.
