BIOS archive for the HP EliteBook 850 G5 tied to board number 605A2945601-MB-A01, revision A1, with a COMPUTRO tag in the name. The title mentions 16MB and 32MB, indicating images for both flash sizes used on this design, and the 16.7 MB RAR suits that content. Technicians use such dumps to reprogram the SPI BIOS chip with an external programmer when the notebook fails to post or is locked. Identify which chip size is fitted on your board, back up the original contents and confirm the A1 revision before flashing.
