Original BIOS dump for the HP ProBook 450 G3 with the tag N78_0149, likely the HP family code N78 and version 01.49, in a 4.70 MB rar. The Orig prefix suggests an unmodified read from a working unit. It can be written to the SPI chip with an external programmer to restore a failed board. No board number is listed, so verify the motherboard code on the PCB, back up the existing chip contents, and confirm the image size equals the flash capacity.
