Working BIOS dump for Quanta board DAN73AMB6D0, revision D, tagged with 8CC9240HQ6, which appears to be a serial number of the source unit. Since such an image may carry that machine's identity data, the serial and related details might need correcting afterwards. The DA-prefixed board number is Quanta's pattern. Write it with an SPI programmer after taking a backup of the original chip, and check that the image size matches the flash chip and that the PCB revision is D.
