4 MB BIOS image for the Acer Aspire E1-571 on an Intel Ivy Bridge board, labelled SL8JC, BIG and OK. It is the larger of a two-chip set; a 1 MB SMALL companion file exists for the second flash device. Technicians program it to the main SPI chip with a CH341A or similar tool when the notebook has no POST or a failed update. Read and store the original contents of both chips first, and check that the chip in your board is 32 Mbit so the image fits.
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 @biosbigarchives. Enginerys does not host this file.
