BIOS for the Huawei MagicBook 14 with motherboard DAH98RMBAD0 revision D, archived in rar at 3.81 MB. The DA-prefixed number with MB suffix follows the Quanta scheme, showing Quanta as the board maker. Technicians program the image to the SPI flash with an external programmer to fix boot failures or corrupted firmware. Check what the archive contains, compare the image size to the chip capacity, and read the original chip first so unique system data can be restored. Make sure revision D matches the PCB.
