BIOS archive for the HP ProBook 650 G1, with the board number 6050A2566301 run together with the model name, revision MB-A04. The 6050A format is an Inventec PCB part number. At 5.97 MB the archive likely contains an image for the SPI flash and possibly ME data. It is used to recover boards with corrupt firmware by writing the chip with a programmer. Verify the board number and A04 revision on the PCB, and back up the original chip first.
