ROM image for the ASUS K550JK laptop, 8.00 MB, carrying 17.4 in the name, which may denote a BIOS version or board revision; the name does not say which. The size suits a 64 Mbit SPI flash chip. Such a file may be a full chip dump or a vendor capsule, so inspect it with a UEFI tool before programming it raw. Save a copy of the original chip contents first, and check the board marking and flash capacity on the motherboard.
