BIOS dump for the Acer Aspire ES1-731 laptop on the Quanta DAZYLBMB6E0 main board, revision E, in a 3.55 MB RAR file. Quanta marks its boards with a DA0 or DA prefix followed by a project code and an MB revision suffix. Use the image to recover a laptop with corrupted firmware by writing it to the SPI flash with a programmer. Save the existing chip contents first, since they may hold system-specific data, and confirm the image size and the board revision before writing.
