Working BIOS binary for the HP Compaq Presario CQ62 on Quanta board DA0AX2MB6E0, revision E. Quanta uses DA0-prefixed mainboard numbers, and the letters before MB identify the project. A known-good dump like this is written to the SPI chip with a programmer to recover a laptop stuck with no display after a bad flash. Back up the current chip contents first, check that the file size matches the chip, and confirm the revision on the PCB.
