BIOS image for the Acer E5-572 on Compal board LA-B702P revision 1.0, with a date of 2015-7-17 in the name, likely the firmware build date. Stored as a 3.65 MB RAR, it helps recover a laptop from a corrupted BIOS by writing the SPI flash with a CH341A or similar programmer. Compal uses LA- numbers for its boards. Save the current chip contents first and verify that the image size suits the installed flash chip.
