BIOS plus EC firmware for HP machines using the Quanta DA0AX1MB6H0 mainboard, revision H, marked fully working. This 3.89 MB RAR package is for the H0 board code, which differs from the H1 variant in its final characters, so check the sticker or silkscreen carefully before choosing it. Technicians flash such images with an external SPI programmer to recover dead or looping boards and to restore the keyboard controller code. Always save the original dumps before writing.
