*update*
the problem seems to be linked with the power splitter board. there was solder linking two bridges which was causing the auto boot once power was supplied, thats now fixed and the power buttons work.
although now we can't get the chip into the flashbios app. we have banks 1 and 2 on, with 3 and 4 off, and flash protection off. pressing both power and eject makes it boot, shutdown, boot, shudown, then boot with red flashing LED.
Also, the DVD drive won't open with the eject button is pressed on its own.
