Acer Aspire E1-431 BIOS dump in a RAR archive, for board DAZQSAMB6F1. The DA0/DAZ...MB6x pattern is Quanta's, so Quanta designed this mainboard, with ZQSA as the project code. The name does not state the flash chip type or whether the ME region is cleaned, so inspect the image after extracting. Use it to reflash the SPI BIOS chip with an external programmer when the laptop has no display or is stuck in a boot loop. Read and back up the original chip first, and make sure the image size equals the chip capacity.
