1)The POST 92 means BIOS stuck while waiting for the PCIE end device OptROM to respond, but it doesn’t, so BIOS is stuck at POST 92 forever.
Here are steps that you can try: Clear CMOS (shutdown the system and pull power cords, remove the onboard 3.5V battery. Touch either the battery +/- terminal with a screw driver or touch the JBT1 pad >< After performed the task, put the battery back and try again.
If problem persists, it could be other PCIe devices like NVME drives that causing the stuck. Temporarily pull all four Kioxia CD6 NVME and try again.
