BIOS image for the ASUS Z87-K desktop motherboard, packed in a RAR archive and described by its name as fully working. Z87 is the Intel chipset for LGA1150 processors. A dump like this is used to recover a board with a corrupted SPI flash by writing it with a programmer such as a CH341A. Read and save the original chip contents first, confirm the image size matches the flash capacity, and expect the serial number and MAC address to need restoring after the flash.
