Firmware for the Acer Aspire E5-731, configuration 45SB, labelled BIOS version 1.07. Supplied as a 2.15 MB ZIP archive to be unpacked before use. Technicians use such an image to recover a board that stopped posting after a failed update, writing it to the SPI flash with a CH341A or similar programmer. No board number is given in the name, so check the motherboard and chip first. Make a full backup of the existing firmware, and confirm the image matches the chip capacity before erasing it.
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.
