Firmware dump for the Acer Aspire E5-521 notebook in the 46QC configuration, provided as a 2.75 MB ZIP. The name gives no board number, version or Management Engine status, so check the contents before flashing. This laptop line uses a soldered SPI BIOS chip that can be programmed in circuit with a clip or removed and written in a programmer to recover from a corrupted BIOS. Make sure the image size matches the chip capacity, and keep a backup of the original firmware before writing anything.
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.
