Working BIOS image for an Honor MagicBook on Quanta board DAH97AMBAD0, with an 8 MB flash size stated in the name. The 8 MB capacity corresponds to a 64 Mbit SPI chip, so confirm the chip marking matches before programming. Quanta places the DA board code on the PCB silkscreen, which is the best way to verify compatibility. Use a programmer such as CH341A or RT809H to restore firmware on a dead or bricked board, and always read and keep the existing contents before erasing the chip.
