Backup BIOS read from an Acer desktop built on the H61H2-M2 motherboard, stored in a 2.90 MB RAR archive. The name marks it as a backup taken from a working machine, so it should carry the Acer-branded firmware rather than generic ECS code. H61H2-M2 is an ECS board for Intel H61 systems. Such a backup is useful for reprogramming the SPI chip with a programmer after a failed update or chip corruption. Save the current chip contents first, compare the board marking, and confirm the image size fits the installed flash chip.
