BIOS firmware package for the HP ProBook 450 G6 laptop, built on the DA0X8JM8E0 motherboard at revision E, packed as a 6.86 MB RAR archive. The DA0 prefix follows the Quanta board-numbering pattern, so check the silkscreen on your PCB for the same code and revision before flashing. Technicians use such a dump to recover a board that will not post or shows a corrupted firmware, writing it to the SPI chip with a programmer. Always read and save the original chip contents first, and confirm the image size matches the flash capacity.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
