Huawei laptop BIOS for Quanta board DAH9ABMBAC0, revision C, stated as a working 32 MB image. The 32 MB size corresponds to a 256 Mbit SPI flash chip, so confirm your board carries that capacity before writing. Quanta encodes its project code and revision in this DA-prefixed number. The image is used to recover boards with corrupted firmware via an external programmer. Read and store the original chip contents, which can include serial and licence data, before programming the dump.
