BIOS image for the Acer Aspire AS5749 built on the Quanta board DA0ZRLMB6D0, revision D, with firmware version 1.08 noted in the name. The DA0 prefix followed by a platform code and MB is the Quanta numbering style, and the printed number and revision on the PCB should match before you use the file. The 4 MB size suits a 32 Mbit SPI flash. Program it with an external programmer after reading and keeping the original chip contents, which helps restore a board that powers on with no image.
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 @bios_laptop. Enginerys does not host this file.
