BIN image labelled for the E5-571G-57D9 on the Compal LA-B991P board; the AVER prefix is likely a misspelling of Acer, though the name does not confirm the brand. The ZIP is 4.05 MB, slightly larger than a bare dump, so check what it contains after extraction. Typical use is reprogramming the BIOS chip with a hardware programmer on a board that will not POST. Make sure the extracted image matches the chip size, and save the original read before flashing.
