BIOS dump for the HP ProBook 6560b, a 4.00 MB binary whose name is marked OK several times, suggesting it was tested and working. The name also contains OPK, whose meaning is not certain. No board number or version is listed. A technician would program this image into the SPI flash to restore a laptop with corrupted firmware.
