Firmware dump for the Acer Aspire ES1-411 laptop, built on mainboard DA0Z8AMB4E0 revision E, archived as RAR at 2.76 MB. The DA0 prefix with MB in the code follows the Quanta numbering pattern, so Quanta is the board maker behind this Acer model. Such an image is written to the SPI BIOS chip with an external programmer to recover a board that does not post or has a corrupted BIOS. Verify the board number and revision on the PCB, back up the existing chip, and make sure the image size fits the flash chip.
