BIOS for the HP ProBook 645 G1, mainboard 6050A2567101-MB-A03, packed as a 2.62 MB RAR. The 6050A prefix is the Inventec numbering used on many HP notebook boards, and the A03 suffix marks the board revision. Technicians flash such images with an SPI programmer to recover boards with corrupted firmware. Read the original chip first, as HP stores serial and product data there, and confirm the board number and revision on the PCB match.
