BIOS dump for the HP ProBook 4540, misspelled in the name, as an 8 MB raw binary. The name marks it as 100 percent OK, indicating the uploader tested it working, though no board number or version is included. Such images are written to the SPI flash with a hardware programmer to recover a laptop with damaged firmware. Before writing, back up the original chip, which on HP boards also holds machine-specific data, confirm it is 8 MB, and verify the board matches the 4540.
