Firmware archive for the Acer Aspire E1-472 with board code EA40 HW and motherboard number 12243-2. A five-digit number with a dash suffix like this is the pattern Wistron uses for its boards. The RAR is 2.99 MB and is intended for reprogramming the BIOS SPI chip on a board that will not post or shows no image. Check the number silkscreened on the PCB matches, read and back up the existing chip first, and verify that the extracted file size equals the chip capacity before writing.
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 @biosarchive. Enginerys does not host this file.
