Firmware dump for the Acer Aspire ES1-411 on Quanta board DA0Z8AMB4E0, revision E, stored as a 2.72 MB rar archive. Quanta numbers follow the DA0 plus project code plus MB pattern, with the last characters giving the revision. The image is used to reprogram the SPI BIOS chip with an external programmer when the notebook fails to start or after a corrupted update. Confirm the board number and revision letter on your PCB, back up the original chip and verify the extracted file matches the flash capacity.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
