BIOS dump for the HP Chromebook 11 G5 on a Quanta DAH9BBMBCA0 motherboard. Chromebook firmware is typically a coreboot-based image on a small SPI chip, and the name does not state the chip type or version, so inspect the extracted binary and compare its size with the chip. Write-protection settings and the stored hardware ID can affect booting. Read the original contents and save them before programming, and confirm that the Quanta code on the PCB matches exactly.
