BIOS for a Huawei laptop built on the Quanta board DAH98NMB8C0, revision C, in an 11.1 MB RAR. The DA...MB pattern is Quanta's board numbering, with H98 as the project code and the trailing letters reflecting the revision. The name lists no model or version, so identify the laptop from the board itself. Write the image to the SPI flash with a programmer after reading and saving the original contents, and verify the image size matches the chip before flashing.
