HP ProBook 430 G8 firmware for Quanta board DAX8PBMB8D0 with project code X8PB, containing a 32MB BIOS image and the EC firmware. HP outsources this platform to Quanta, whose numbers start with DA and use the project code in the middle. Reflashing both the BIOS and EC can revive a board with no power, no display or a corrupted keyboard controller. Back up the existing chips first, keep the original serial data, confirm the board number on the PCB and check that the flash chip is 32MB.
