Combined BIOS and EC firmware for the Acer Aspire E1-471G, board DAZQSAMB6E0 revision E, in a ZIP archive. The DA0/DAxxxxMB pattern is Quanta numbering, so Quanta is the ODM for this board.

Confirm the revision letter on the PCB, read both chips before overwriting them, and check that each file size matches the corresponding flash chip.
