BIOS for the HP Z240 SFF workstation, a 16MB image compressed into a 7.44 MB RAR. The capacity indicates a 128 Mbit SPI flash chip, and the image should only be written to a chip of the same size. Technicians use such dumps with an external programmer to repair boards that do not boot after a failed update. Read and keep the original contents, which contain the serial number and other unit data, and verify the board is the SFF variant.
