BIOS image for the Intel DZ77SL-50K desktop motherboard, an 8MB dump inside a RAR archive. The Z77 chipset puts the board on Intel's Ivy Bridge and Sandy Bridge desktop platform. An 8MB image matches a 64 Mbit SPI flash and is written with a programmer when the board no longer posts after a failed update. Read and keep the existing contents first, since they hold the MAC address and board data, and confirm the chip capacity on the board so the image fits correctly.
