BIOS image for the HP Compaq Presario CQ42-116tu and 227tu, Core 2 Duo models with DDR2 memory, on Quanta board DA0AX3MB6C0 revision C, in a 1.67 MB ZIP. The DA0 prefix with AX3 project code follows Quanta numbering used across many HP boards. Write the dump to the SPI chip with a programmer to recover from no POST or failed updates. Make sure the board code and revision letter on the PCB match, keep a backup of the original chip, and check the image fits the flash size.
