BIOS firmware for the HP TPN-Q174, a regulatory model code, built on the Quanta board DAG38DMBCC0, revision C. The RAR archive should contain an SPI flash image to restore boards with corrupted firmware that power on without display or fail to boot. Program it with an external flasher after reading and saving the original chip, since system identifiers may be stored there. Confirm the board number and revision on the PCB first and check that the image matches the capacity of the installed flash chip.
