Firmware dump called sgn.bin, 2 MB, with no brand, model or board number given. The abbreviated name gives little to go on, so the file should be treated as unidentified until its contents are examined with a hex viewer or a BIOS editor. Its size matches a 16 Mbit SPI flash chip of the type used for system BIOS on many notebooks. Technicians write such images with a hardware programmer to revive a board with corrupted firmware. Read and save the existing chip, and confirm the board number before writing.
