ZIP archive of about 3.71 MB containing BIOS firmware for the Acer Aspire E5-474 notebook; the name does not say whether it holds a single dump or several files. Extract it and check the size of each binary against the SPI flash chip on your board, since an image that does not match the chip capacity will not fit. The motherboard number is not stated, so compare the PCB markings before use. Back up the original chip, then write with an external programmer to recover a laptop that will not post or display.
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 @abgm_manutencao_bios. Enginerys does not host this file.
