BIOS image for the HP ProBook 450 G4 on Quanta board DA0X83MB6H0 at revision H, labelled as fixed, meaning a repaired or corrected dump. The DA0 prefix is the Quanta notation for main boards. Flash it to the SPI chip with a programmer to restore a board that will not post or has corrupted firmware. Keep a backup of the original chip, since it holds unit-specific data, confirm the revision on the PCB, and check that the image size matches the flash.
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.
