BIOS dump for a laptop mainboard numbered DAR23GMB6A1, revision A, paired with an AMD A4-3300M processor, in a 1.41 MB RAR archive. The DA prefix with MB in the code follows Quanta numbering, so the board comes from that ODM regardless of the brand on the lid. Use the image to reprogram a corrupted SPI flash with an external programmer after reading and keeping the existing contents. Check that the board code and revision printed on the PCB match, and that the image size equals the capacity of the flash chip.
