BIOS archive for the Acer Aspire E5-475G, Quanta board DAZ8VMB18D0, revision D, marked as working. The G suffix of that model usually denotes a version with dedicated graphics, so match the board configuration before flashing. The 5.83 MB RAR should contain an image for programming the SPI flash directly with a CH341A or similar tool. Quanta encodes the project and revision in the DA board number. Save a full read of the original chip first and verify the written image afterwards.
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 @schematiclaptopramkushwaha. Enginerys does not host this file.
