Since the BIOS chip has no socket, I have a SOIC8 clip adapter and a TL866 EEPROM programmer to repair the motherboard, but The problem starts here.
When I try to flash the BIOS chip, it complains about over-voltage protection and can’t even read from the chip. I have a working board and tried the same: read the EEPROM chip, the same The problem occurs.
The question is: Has anyone managed to refresh the Supermicro BIOS chip? Block custom programmers can write circuit locks on the chip without removing the chip from the board?
Thanks in advance,
On Sun workstations, we install a known good chip, start the machine, and then pull down the chip when the power is turned on, and turn on the bad chip. Reprogramming in the plug-in to deal with this kind of problem. Obviously this is a super scary program. There are many risks, you may end up blowing up the chip, the motherboard or both. I have never tried it on a PC, so I can’t Recommend it with a clear conscience. I will say that I made about six Sparcstation SLCs, but they all survived.
I have a Supermicro server that is out of warranty , And it committed suicide last month. Yes, that’s it. During the AMIB IOS update process, the B IOS watchdog has tripped and the motherboard reset during flashing. We finally got a non-functional motherboard.

You are not talking about what kind of Supermicro motherboard it is, or how big it is. Some motherboards have the final failure Protect the BIOS update method; usually it involves connecting a floppy disk drive, inserting the disk with the new BIOS, and then setting jumpers or pressing a key combination when powering up. If it is available, this may be your best choice.
