BIOS for the Acer Aspire E1-431 built on the Quanta DAZQSAMB6F1 motherboard, in a 2.88 MB RAR. Quanta numbers its boards with a DA prefix, a project code such as ZQS and a revision suffix, and they appear in several brands. Use the dump to reflash the SPI chip with a programmer when the laptop shows no image or will not start. Compare the full board marking on the PCB, dump the existing chip as a backup, and check that the file size matches the flash capacity.
