BIOS for the Acer Aspire A315-57G, which the name identifies only by model code, with the Intel Management Engine region cleaned. A clean ME image lets a reflashed board start without the ME errors or delayed power-on caused by a corrupted region. The archive is 5.75 MB in compressed form. Read and save the original SPI flash first so that serial and MAC data can be carried over, then check that the image size matches the chip before writing it with a programmer.
