Working BIOS for the HP model with regulatory code TPN-Q214, Quanta board DA0G7DMB8D0 at revision D, taken from a unit with an 8th-generation Core i5 and marked as 100% working. The 24.0 MB RAR holds a dump for direct SPI chip programming. Quanta DA0 board numbers end with a revision letter, so confirm that the PCB reads DA0G7DMB8D0 before use. Back up the original flash contents first, as HP stores serial and product data in the chip that may need restoring.
