Firmware dump for the ES1-111M on Quanta board DA0ZHKMB6C0, revision C, marked OK, in a 2.73 MB RAR archive. Quanta boards carry DA0-prefixed numbers on the PCB, with the trailing characters indicating board family and version. The image is written to the BIOS SPI chip with an external programmer to recover a unit with corrupted firmware. Check that the PCB number and revision C match, save the original chip contents first and confirm the size matches the flash.
