I have a 3 node cluster running 7.3.1 and while updating LCM complained that it cannot update NICs but I need to do manually listing KB-10634. I downloaded the x722 0x800042eb update file, executed and failed at the last minute and after the update both NICs are disappeared. I spoke with Supermicro and they are not willing to do anything because the motherboard serial is more than 5 years old and OOW. But one of the Tech advised me to program this chip (AT45DB041E-SSHN) with the 722M4B.bin file at my own risk and discretion, which I did, but nothing changed. nvmupdate64e just cannot see/find these two NICs.

So what I tried next was to copy the above chip content from the second good known server and programmed the corrupted chip, but still nothing changed. The good new is that I can still install and use the latest AOS with a PCIE add on X550 card and the server works fine.

But, I still would like to get those 2 x722 onboard NICs back and I really appreciate your help regarding this and thank you in advance.
