It is a compressed archive of roughly 1.94 MB, most likely containing an SPI flash image used to revive a unit with corrupted firmware, no POST or a looping boot. Open it, check the image size against the flash chip on the board, and read the original contents with a programmer before writing, so serial data and settings can be restored if needed.
