BIOS firmware for the Acer Swift 3 SF314-55 on the MI4FA board, version 1.07 according to the name. The 5.58 MB RAR may contain an update package or a raw flash image, so check its contents before using it. A raw image is written to the SPI chip with a programmer to recover a laptop that does not post after a failed update. Always save a dump of the original chip first and confirm the image size matches the flash capacity before writing.
