Working BIOS dump for an HP 15-CS laptop on Quanta board DA0G7EMBAE0, revision E, platform code G7E, taken from a unit fitted with an Intel Core i7-8665U. The name reports the image as fully working. DA0xxxMBxx0 is the Quanta numbering style used on many HP consumer boards. Write it to the SPI flash with a programmer such as a CH341A after saving a copy of the original chip, and confirm the image size equals the chip capacity. Matching the CPU variant and board revision lowers the risk of a no-boot after flashing.
