Working BIOS for a Quanta DA0ZHYMB6E0 board, revision E, based on the ZHY project. The name gives no laptop brand or model, so identify the unit by the board number on the PCB. Quanta uses the DA0 code, MB and revision-letter pattern for its boards. The 6.48 MB RAR holds an image for reflashing the SPI chip with an external programmer when the firmware is corrupted. Back up the original contents first and confirm that the image size matches the chip capacity.
