BIOS firmware for a Microsoft Surface identified by the name as model 1724, with the board part code X911788-009, in a 5.63 MB RAR. The name gives no version, chip type or tested status, so treat it as an unverified dump. Such an image is written to the SPI flash chip with a programmer when the device fails to boot because of corrupted firmware. Surface boards are tightly integrated, so read and keep a backup of the original chip, compare the board code on your PCB and confirm the image size matches the chip.
