An original firmware dump for a 450 G3, probably an HP ProBook 450 G3, noted in the name as coming from an i7 configuration. Because it is an original read, it should hold the stock BIOS and ME data as the board shipped. At 16 MB it fits a 128 Mbit SPI flash. Technicians flash it with a hardware programmer to revive boards with a corrupted BIOS. The CPU variant may matter, so compare it with your board, and keep a copy of your own chip before writing.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
