ProBook firmware for board revision MB-A02, with the number written as 605A2566301. That appears to be a truncated form of 6050A2566301 used by the ProBook 650 G1 board, though the name does not state the model. The archive is 5.97 MB, the same size as the A04 dump. Typical use is restoring the SPI BIOS with a hardware programmer. Confirm the actual PCB number and revision, ensure the image fits the chip, and keep a backup of the existing contents.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @afsbiosfree. Enginerys does not host this file.
