BIOS firmware package for the Acer ZS8 R7 series laptop, built on motherboard DA0ZS8MB8E1 at revision E. The DA0...MB... numbering follows the Quanta pattern, so Quanta is the ODM that designed the board even though it ships under the Acer name. Packed as a RAR archive of 3.66 MB, it is meant for reflashing the SPI BIOS chip with a hardware programmer such as a CH341A. Confirm the board number and revision on the PCB match, and read and save the original chip contents before writing anything.
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.
