from the chart, this motherboard using the is the SPI BIOS directly with EC connected in standby BIOS and EC work conditions intact the circumstances should have data transmission, so there will be waveform existence
test BIOS, Pin 5 follows waveform – V | – of W7 t3 _; Z (v

next trigger power-on trigger after the SPI BIOS normal, then the waveform should be changed quickly than ever before, but as the waveform on the oscilloscope and the standby, so continue up measuring LPC bus EC Model KB926 chip number U33, U33 of 4,5,7,8,10 connected to the Southbridge, which a few feet waveform, then, the machine did not go to the code. Test U33 4 feet LFRAME # waveform. I am sure the board is not run code ; {8 Y-`# [9 m! _ * U5, T 5 j6 I0 is J / G + o) i
