BIOS for the HP 540 and 550 laptops on mainboard 6050A2216301-MB-A02, packed as a 555 KB RAR. The 6050A board number follows the Inventec numbering pattern, so Inventec is the ODM, and A02 marks the board revision. Technicians write this image to the SPI flash with a programmer to recover a laptop with corrupted firmware or a no-display fault. Before writing, compare the board number and revision printed on the PCB with this one, check that the image size matches the flash chip, and keep a backup of the original.
