Locate the 8-pin BIOS chip on the board (usually near the IO chip or Southbridge).
In many cases, the BIOS chip on this board contains data that must match the main board. Replacing just the board might result in a "no-boot" scenario.
💡 Always back up your current BIOS using a tool like CH341A Programmer or Universal BIOS Backup ToolKit before attempting to flash a file found online.
