BIOS dump for a laptop board numbered DAG35NMB8B0, described in the name as a fully working image, packed in a 6.97 MB RAR. The DAxxxxMBxxx pattern belongs to Quanta, an ODM that builds boards for several laptop brands; the brand is not stated here. Use it to recover a board with a corrupted BIOS by writing the SPI chip with a programmer. Save the original contents first, confirm the image size matches the chip capacity and check the board number printed on the PCB.
