X470D4U2-2T no POST after BIOS update

   I have a problem with my X470D4U2-2T Server motherboard.

 I was trying to install a Windows Server 2022 but it kept restarting when windows server setup was initializing.

I thought a new bios update would fix it, as google AI was telling me, so I installed the latest BIOS, version 4.10 . Completed successfully, it asked for a restart but after that server never started again. Dr. debugger screen doesn't even light up to show an error code.
I thought connecting to IPMI would be an option, even though i never used it before so I also tried connecting all the network ports to my router, but no new network device shows up in the list.

BMC version is F/W P1.70.00 (never updated) , original BIOS was P3.30 (now should be 4.10).

What can I do to fix this?

The AI is suggesting me to buy a CH341A USB Programmer, remove the bios chip and flash it. Is this the only option?

	Try following the instructions here. That should flush any corrupt values from your BIOS. Once you power the system back on again, leave it powered on for at least 10mins to rule out any pre-POST initialization that may be taking a while on first boot on the updated BIOS. If all that fails then open a support ticket with ASRock Rack: https://event.asrockrack.com/tsd.asp

	There is also a handy BMC (IPMI) user guide on your product page. It should have all you need to log in and troubleshoot. Page 61 (64 in the PDF) is probably what will be most useful to you if the steps I listed didn't resolve the issue. Good luck.
