BIOS dump for a Sony laptop built on the Quanta DA0HK9MB6D0 motherboard, revision D, UMA version meaning integrated graphics only, marked as working. Packed in a 3.21 MB RAR archive. This image is meant for writing straight to the SPI flash with a programmer when the machine fails to boot or the firmware is corrupt. Quanta boards carry their number on the PCB silkscreen, so confirm both the number and revision D, and verify you have the UMA board rather than a discrete graphics one. Save the original chip content first.
