BIOS dump packed in a RAR archive for the Acer Aspire A315-55G, built on Quanta board DA0ZAWMB8E0 revision E, intended for the 10th generation Core i5 variant. The DA0 prefix with an MB suffix is Quanta's motherboard numbering, so confirm the code and revision silkscreened on the PCB before writing. Extract the image, read and save the original SPI chip contents with a programmer such as a CH341A, and check that the file size matches the flash capacity before flashing, since a mismatched image will not fit.
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.
