Refer to the wiring production of HIPC boot card and have tested it.
Other boot cards that use the 4th, 8th, 10th wires or the 4th and 10th wires on the high side of the PCIe component can also be used.
Line 4 gnd
The 8th line has 3.3 output after booting (used for high-end boot cards to detect whether the computer is powered on)
The 10th line has a 3.3v output when plugged into the power supply (used as the main power supply for the boot card)
The three-pin socket is PH2.0mm. Don’t buy something weird that the software automatically matches.
Pay attention to the line sequence when arranging the cables. Both boards have GND on the side.
