BIOS image for the Quanta board DAD91AMB6E0, revision E, in a 4.25 MB RAR archive; the name does not state the laptop model or brand. The DA...MB6 pattern is Quanta's board numbering, and this code also appears on HP Pavilion x2 10-p boards. A dump like this is written to the SPI flash with a programmer such as a CH341A to revive a board with corrupted firmware. Read and keep the original chip contents first, and confirm that the image size fits the flash chip before writing.
