BIOS for the HP ProBook 640 G1 motherboard 6050A2566302, version MB A04, packed in a 6.86 MB ZIP. The 6050A prefix is the board numbering used by Inventec for HP business notebooks, and the A04 suffix marks the PCB revision. Such a dump is written to the SPI flash with a programmer to recover a board that fails to start after corruption. Back up the original chip first, since HP stores serial number and product data in the flash, confirm the image size matches the chip, and check the full number printed on the PCB.
