Working BIOS for the HP ProBook 430 G4 using the Quanta X81 board DA0X81MB6E0, revision E. The 4.94 MB RAR is meant for programming the SPI flash directly when the notebook will not POST, shows caps lock blinking codes from corrupt firmware or failed an update. Quanta prints the board number and revision on the PCB, so check them first. Read and store the original chip contents before erasing, because they hold the serial number and product data that HP firmware relies on.
