Main BIOS dump for the Acer Aspire E5-471 configuration 30DG, an 8 MB binary from a Brazilian diagram collection. The name gives no board number or ME status, so check the mainboard label before using it. An 8 MB image matches a 64 Mbit SPI flash chip, and it is typically written with a programmer such as a CH341A to revive a board that will not post. Save the existing chip contents before erasing, since serial and system data stored there may need to be restored 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 @vinafix_bios. Enginerys does not host this file.
