BIOS archive for an HP 14 laptop on Quanta board DA0P9CMB6C0, revision C, compressed into an 8.47 MB RAR. In the Quanta scheme, DA0 is followed by the project code P9C, MB denotes the mainboard and the final characters give the revision. The contents are meant for writing the SPI flash with a programmer when the notebook shows no display, boot loops or corrupted firmware. Confirm the PCB revision letter is C, save a dump of the original chip and check that the image size matches the flash capacity.
