BIOS dump for the HP ProBook 440 G3 main board DAX61CMB6C0, revision C, stored in a 4.69 MB RAR archive. The DA-prefixed board number follows Quanta's numbering, so Quanta is the ODM behind this HP design. Technicians write such images to the SPI flash with a programmer such as a CH341A to revive a board with corrupted firmware. Read and save the original chip contents first, and check that the image size equals the flash capacity before writing, or it will not fit.
