Firmware dump for the HP ProBook 6450b built on motherboard 6050A2326601, supplied as a 1.91 MB RAR archive. Board numbers beginning with 6050A follow the Inventec numbering pattern, and Inventec manufactured many HP business notebooks of this era. The image is meant for direct programming of the BIOS flash chip when the laptop will not start or a failed update has left it dead. Check that the number silkscreened on the PCB matches exactly, read and store the original chip first, and verify the image size against the chip capacity.
