BIOS dump for an HP 15 laptop built on Quanta board DA0G7HMB8H0, revision H, sized for a 16MB SPI flash chip. The DA prefix and MB suffix follow Quanta motherboard numbering, where the middle code names the project. Technicians write such images with a programmer like a CH341A when a board is bricked or the original firmware is corrupt. Read and keep a backup of the existing chip first, confirm the board revision, and make sure the extracted image size equals the 16MB chip capacity.
