BIOS dump for the HP ProBook 450 G5 built on Quanta board DA0X8CMB6E0, revision E, marked as a working image. It comes packed in an 11.9 MB RAR archive, so extract it first and check the size of the binary inside against the SPI flash chip on the board. The DA0 prefix follows Quanta's numbering, and the last characters mark the revision. Confirm the number and revision silkscreened on the PCB, read and save the original chip contents with your programmer, then write this image to recover a dead or corrupted board.
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 @schematiclaptopramkushwaha. Enginerys does not host this file.
